ABSTRACT
Researchers have explored the benefits and applications of virtual reality (VR) in different
scenarios. VR possesses much potential and its application in education has seen much research
interest lately. However, little systematic work currently exists on how researchers have applied
immersive VR for higher education purposes that considers the usage of both high-end and
budget head-mounted displays (HMDs). Hence, we propose using systematic mapping to identify
design elements of existing research dedicated to the application of VR in higher education.
The reviewed articles were acquired by extracting key information from documents indexed
in four scientific digital libraries, which were filtered systematically using exclusion, inclusion,
semi-automatic, and manual methods. Our review emphasizes three key points: the current
domain structure in terms of the learning contents, the VR design elements, and the learning
theories, as a foundation for successful VR-based learning. The mapping was conducted between
application domains and learning contents and between design elements and learning contents.
Our analysis has uncovered several gaps in the application of VR in the higher education
sphere—for instance, learning theories were not often considered in VR application development
to assist and guide toward learning outcomes. Furthermore, the evaluation of educational VR
applications has primarily focused on usability of the VR apps instead of learning outcomes and
immersive VR has mostly been a part of experimental and development work rather than being
applied regularly in actual teaching. Nevertheless, VR seems to be a promising sphere as this
study identifies 18 application domains, indicating a better reception of this technology in many
disciplines. The identified gaps point toward unexplored regions of VR design for education,
which could motivate future work in the field.
1. Introduction
Digital devices are being increasingly adopted for learning and education purposes (Zawacki-Richter & Latchem,2018). This can
particularly be observed in the 1997–2006 period, when networked computers for collaborative learning were intensively used, and
in the 2007–2016 period, when so-called online digital learning became widespread. During these two periods, people examined the

exploitation potential of emerging technologies, such as virtual learning environments (Boulton, Kent, & Williams,2018;Muñoz-
Cristóbal, Gallego-Lema, Arribas-Cubero, Martínez-Monés, & Asensio-Pérez,2017), mobile devices (Wang, Wiesemes, & Gibbons,
2012), and computer-mediated communication (Mason & Bacsich,1998). Recently, virtual reality (VR) technologies are actively being
incorporated into education, teaching, and training in various application domains.
Although VR is not new, the recent developments in immersive technologies – in terms of visualization and interactions – have
made VR increasingly attractive to scholars. The latest VR head-mounted displays (HMDs), such as HTC Vive or Oculus Rift, allow
users to experience a high degree of immersion. Immersion describes the involvement of a user in a virtual environment during
which his or her awareness of time and the real world often becomes disconnected, thus providing a sense of ‘‘being’’ in the task
environment instead. Freina and Ott (2015) define this term as ‘‘a perception of being physically present in a non-physical world by
surrounding the user of the VR system created with images, sound, or other stimuli’’ so that a participant feels he or she is actually
‘‘there’’.
Likewise, low-budget HMDs for mobile devices, such as Samsung Gear VR and Google Cardboard, enable everyone to experience
immersive virtual environments. In addition, the current devices also offer interaction capabilities. While high-end VR equipment
comes with dedicated controllers that support game play (e.g., Oculus Touch), low-budget HMDs, such as Google Cardboard, support
gaze control or enable the user to interact with the virtual environment by providing a magnetic switch.
The HMD market is expected to be valued at USD 25 billion by 2022, growing at a Compound Annual Growth Rate of 39.52%
between 2019 and 2025 (Global Augmented Reality,2019). Therefore, the time is ripe to study immersive VR, primarily due to the
increased capability of VR technology and reduced costs. For example, the recently released Oculus Quest comes in the form of a
cordless HMD. While the design enables the user to move more freely, the cost is set at approximately 400 USD—pretty much the
same price as the previous generation Rift with cables.
Moreover, VR has been described as the learning aid of the 21st century (Rogers,2019). A study suggests that students retain
more information and can better apply what they had learned after participating in VR exercises (Krokos, Plaisant, & Varshney,
2019). Considering the potential learning enhancement through VR use, it is understandable why researchers, organizations, and
educators nowadays scrutinize this technology intensively, looking to add an extra dimension to the classroom with respect to both
teaching and learning.
Due to the increasing scholarly attention paid to VR technologies, there are already a few comprehensive overviews and
systematic mappings of VR applications for education (Jensen & Konradsen,2018;Merchant, Goetz, Cifuentes, Keeney-Kennicutt, &
Davis,2014). For example, Merchant et al. (2014) focus on desktop VR in education while Jensen and Konradsen (2018) emphasize
the application of HMD technologies. Although Jensen and Konradsen (2018) have a similar focus to this review, which is in terms
of learning experience and learning outcome, they are not specific about their target audience (such as K12, higher education,
vocational training, or job training). Besides, these two studies do not examine underlying learning theories governing the VR
application development and the design elements of the VR applications.
Hence, in this paper, we focus on the use of immersive VR in higher education and answer the following questions:
How are immersive VR technologies embedded into higher education?
What design elements, learning contents, and immersive technologies have been laid out to support VR-based learning?
What learning theories have been applied to guide VR application design and development for higher education?
What evaluation methods have been employed to evaluate the learning outcomes?
What higher education domains have applied VR to teaching and learning?
In this article, we carry out a systematic mapping of the existing VR literature and highlight the immersive aspect of VR to
answer these questions, which are presented in detail in Table 2. Our aim is to contribute to the extant body of knowledge on the
application of digital devices for educational purposes.
This work is organized as follows: In Section 2, related works on systematic reviews of VR in an educational context are presented.
The section concludes with a gap analysis and an explanation of how our work addresses the noted gaps. Then, our research design
is described in Section 4, including our literature identification search procedure, our semi-automatic filtering process, and analysis
methods. In Section 5, four analysis frameworks (1. research design,2. research method and data analysis,3. learning, and 4. design
element) and their sub-frameworks are formulated as an overarching category foundation for the consolidation and analysis of
the results. Drawing on this classification, we identify patterns of VR design element use for specific learning contents in higher
education. The results are discussed in Section 6to highlight the implications, opportunities for future research, recommendations
for lecturers, and limitations of our work. Finally, we draw a conclusion in Section 7. Three appendices (from p. 32) provide more
detailed information about certain aspects of our research design as well as a list of articles included in our literature study.
2. Theoretical background
In this section, we draw the background of the two main topics combined in this paper: immersive VR and learning theories.
Bringing these topics together allows us to analyze the usage of VR in the higher education context.
2.1. VR and immersion
VR can be defined as ‘‘the sum of the hardware and software systems that seek to perfect an all-inclusive, sensory illusion of
being present in another environment’’ (Biocca & Delaney,1995). Immersion, presence, and interactivity are regarded as the core
Computers & Education 147 (2020) 103778

J. Radianti et al.
characteristics of VR technologies (Ryan,2015;Walsh & Pawlowski,2002). The term interactivity can be described as the degree
to which a user can modify the VR environment in real-time (Steuer,1995). Presence is considered as ‘‘the subjective experience of
being in one place or environment, even when one is physically situated in another’’ (Witmer & Singer,1998). While researchers
largely agree on the definitions of interactivity and presence, differing views exist on the concept of immersion. One branch of
researchers suggests that immersion should be viewed as a technological attribute that can be assessed objectively (Slater & Wilbur,
1997), whereas others describe immersion as a subjective, individual belief, i.e., a psychological phenomenon (Witmer & Singer,
1998).
Jensen and Konradsen (2018) suggest an additional perspective concerning the positive effects of immersion and presence on
learning outcomes. The results of the reviewed studies in their work show that learners who used an immersive HMD were more
engaged, spent more time on the learning tasks, and acquired better cognitive, psychomotor, and affective skills. However, this
study also identifies many factors that can be reinforcers or barriers to immersion and presence. Both graphical quality of VR and
the awareness when using VR, for instance, can reduce the sense of presence. Individual personality traits may also be associated
with a limited acquisition of skills from using VR technologies.
According to the technological view, the term immersion means the ‘‘extent to which the computer displays are capable of
delivering an inclusive, extensive, surrounding, and vivid illusion of reality’’ (Slater & Wilbur,1997). More precisely, this includes
the degree to which the physical reality is excluded, the range of sensory modalities, the width of the surrounding environment as
well as the resolution and accuracy of the display (Slater & Wilbur,1997). The technological attributes of a VR technology – such
as the frame rate or the display resolution – consequently determine the degree of immersion that a user experiences (Bowman &
McMahan,2007). In contrast, the psychological point of view considers immersion to be a psychological state in which the user
perceives an isolation of the senses from the real world (Witmer & Singer,1998). According to this view, the perceived degree of
immersion differs from person to person and the technological attributes barely influence it (Mütterlein,2018).
With our systematic mapping study, we aim to identify the current applications of immersive VR in higher education. For this
reason, we set specific inclusion and exclusion criteria to distinguish papers that describe immersive VR applications from papers that
describe non-immersive VR applications. As the subjective experience of immersion could hardly be used as a selection criterion, we
defined certain types of VR technologies as either immersive or non-immersive based on their technological attributes. These specific
technology types were then used as either the inclusion or exclusion criteria. For this paper, we considered mobile VR (e.g., Google
Cardboard, Samsung Gear), high-end HMDs (e.g., Oculus Rift, HTC Vive), and enhanced VR (e.g., a combination of HMDs with data
gloves or bodysuits) as immersive.1These VR technologies allowed the user to fully immerse into the virtual environment (Khalifa &
Shen,2004;Martín-Gutiérrez, Mora, Añorbe Díaz, & González-Marrero,2017). Desktop VR and Cave Automatic Virtual Environment
(CAVE) systems, however, were considered as non-immersive because the user can still recognize the screen or a conventional
graphics workstation (Biocca & Delaney,1995;Robertson, Czerwinski, & Van Dantzich,1997).
2.2. Learning paradigms
An understanding of the existing learning paradigms is essential for performing an analysis of the current state of VR applications
in higher education. Thus, we introduce the main ideas behind the existing learning paradigms. Literature distinguishes between
behaviorism, cognitivism, and constructivism (Schunk,2012). Other scholars also include experiential learning (Kolb & Kolb,2012)
to this list and, recently, connectivism has been introduced as a new learning paradigm (Kathleen Dunaway,2011;Siemens,2014).
Each learning paradigm has developed various theories about educational goals and outcomes (Schunk,2012). Each of these theories
also offers a different perspective on the learning goals, motivational process, learning performance, transfer of knowledge process,
the role of emotions, and implications for the teaching methods.
Behaviorism assumes that knowledge is a repertoire of behavioral responses to environmental stimuli (Shuell,1986;Skinner,
1989). Thus, learning is considered to be a passive absorption of a predefined body of knowledge by the learner. According to
this paradigm, learning requires repetition and learning motivation is extrinsic, involving positive and negative reinforcement. The
teacher serves as a role model who transfers the correct behavioral response.
Cognitivism understands the acquisition of knowledge systems as actively constructed by learners based on pre-existing prior
knowledge structures. Hence, the proponents of cognitivism view learning as an active, constructive, and goal-oriented process,
which involves active assimilation and accommodation of new information to an existing body of knowledge. The learning
motivation is intrinsic and learners should be capable of defining their own goals and motivating themselves to learn. Learning
is supported by providing an environment that encourages discovery and assimilation or accommodation of knowledge (Shuell,
1986),RN23. Cognitivism views learning as more complex cognitive processes such as thinking, problem-solving, verbal information,
concept formation, and information processing. It addresses the issues of how information is received, organized, stored, and
retrieved by the mind. Knowledge acquisition is a mental activity consisting of internal coding and structuring by the learner.
Digital media, including VR-based learning can strengthen cognitivist learning design (Dede,2008). Cognitive strategies such as
schematic organization, analogical reasoning, and algorithmic problem solving will fit learning tasks requiring an increased level
of processing, e.g. classifications, rule or procedural executions (Ertmer & Newby,1993) and be supported by digital media (Dede,
2008).
1It should be noted that immersion apparently has a sociocultural aspect the notion of which changes over time. When the first 3D games were introduced
in the early 1990s, players would consider these to be immersive despite seeing software-rendered graphics in a resolution of 320X160 pixels with 2D sprites,
often displayed on a small CRT monitor.

J. Radianti et al.
Constructivism posits that learning is an active, constructive process. Learners serve as information constructors who actively
construct their subjective representations and comprehensions of reality. New information is linked to the prior knowledge of each
learner and, thus, mental representations are subjective (Fosnot,2013;Fosnot & Perry,1996). Therefore, constructivists argue that
the instructional learning design has to provide macro and micro support to assist the learners in constructing their knowledge
and engaging them for meaningful learning. The macro support tools include related cases, information resources, cognitive tools,
conversation, and collaboration tools, and social or contextual support. A micro strategy makes use of multimedia and principles
such as the spatial contiguity principle, coherence principle, modality principle, and redundancy principle to strengthen the learning
process. VR-based learning fits the constructivist learning design (Lee & Wong,2008;Sharma, Agada, & Ruffin,2013). Constructivist
strategies such as situated learning, cognitive apprenticeships, and social negotiation are appropriate for learning tasks demanding
high levels of processing, for instance, heuristic problem solving, personal selection, and monitoring of cognitive strategies (Ertmer
& Newby,1993).
Experientialism describes learning as following a cycle of experiential stages, from concrete experience, observation and reflection,
and abstract conceptualization to testing concepts in new situations. Experientialism adopts the constructivist’s point of view to some
extent—e.g., that learning should be drawn from a learner’s personal experience. The teacher takes on the role of a facilitator to
motivate learners to address the various stages of the learning cycle (Kolb & Kolb,2012).
Connectivism takes into account the digital-age by assuming that people process information by forming connections. This newly
introduced paradigm suggests that people do not stop learning after completing their formal education. They continue to search for
and gain knowledge outside of traditional education channels, such as job skills, networking, experience, and access to information,
by making use of new technology tools (Siemens,2014).
Of course, there are many varieties of learning theories in addition to the main paradigms listed here, such as those developed
based on the information processing theory or the social cognitive theory. Regardless of which learning theories under each paradigm
are used by VR researchers, it is crucial that the development of VR applications for higher education is firmly grounded on existing
learning theories because learning theories offer guidelines on the motivations, learning process and learning outcomes for the
learners.
3. Related work
In the following section, we first present an overview of literature reviews before discussing the gaps found in existing works.
3.1. Literature reviews
In our search for existing systematic reviews and mapping studies on VR in an educational context, the Scopus digital library
returned 59 peer-reviewed articles published between 2009–2018, which included search terms ‘‘virtual reality’’ and ‘‘systematic
review’’ in their titles and were linked to education,training,teaching, or learning. The most popular application domains covered in
these systematic reviews were medicine (78%), social science (15%), neuroscience (11%), and psychology (11%). We filtered the
search results further by checking the abstracts of these studies for whether the immersion aspect was also included in them.
We found 18 potentially relevant articles, of which four were very relevant for our work and reported the results of a systematic
mapping study. In addition, we found two other thematically relevant articles, one of which described a review and one a meta
analysis. Hence, we examine six review articles in total and introduce them shortly to illustrate the research gap we address with
our systematic mapping study.
Feng, González, Amor, Lovreglio, and Cabrera-Guerrero (2018) conducted a systematic review of immersive VR serious games
for evacuation training and research. The application area was quite specific, i.e., building evacuation and indoor emergencies. The
authors proposed the use of serious games, as these have increasingly been adopted for pedagogic purposes. Feng et al. (2018)
focused on examining immersion through a virtual environment, where the participants could feel that they are physically inside
the artificially simulated environment. The authors identified the pedagogical and behavioral impacts, the participants’ experience
as well as the hardware and software systems that were used to combine serious games and immersive VR-based training. They
reported several pedagogical and behavioral outcomes, which included knowledge of evacuation best practices, self-protection skills,
and spatial knowledge. The typical methods used for measuring the learning outcomes in this study were questionnaires, open-
ended question interviews, paper-based tests, and logged game data (e.g., evacuation time, damage received). Regarding behavioral
impacts, the following points were specified:
Evacuation facility validation (tested and validated different evacuation facility designs and installations),
Behavioral compliance (investigated whether participants followed the evacuation instructions),
Hazard awareness (investigated whether participants could notice hazards in the environment),
Behavioral validation (validated the hypothetical behavior model),
Social influence (examined the social influence on evacuation behavior),
Behavior recognition (identified different behaviors under different evacuation conditions), and
Way-finding behavior (studied evacuation way-finding behavior).
Participants were observed as to whether they showed fear, engagement, stress, and high mental workload during the
training. To track these experiences, the researchers employed an electrodermal activity sensor to evaluate fear and anxiety, a
photoplethysmography sensor to obtain blood volume pulse amplitude, and a multichannel physiological recorder to measure the

J. Radianti et al.
emotional responses of participants. Feng et al. (2018) also mentioned the characteristics of the game environments identified during
the study, i.e., the teaching methods through direct or post-training feedback, navigation, static and dynamic hazard simulation,
narratives – such as action, performance or instruction-driven, interactivity/non-interactivity with non-playable characters – as well
as audio-visual and motion sense stimulation.
Wang, Wu, Wang, Chi, and Wang (2018) specifically surveyed the use of VR technologies for education and training in the
construction engineering field. The authors focused on VR technologies, applications, and future research directions. The study
found five major technology categories used in the construction engineering context—desktop VR, immersive VR, 3D game-based
VR, building information modeling VR, and augmented reality. The authors noted that desktop VR was used to improve the students’
motivation and comprehension. Under immersive VR, the authors subsumed HMDs combined with sensor gloves and suits, the so-
called virtual structural analysis program and CAVE systems, where the immersive virtual environment is formed around the user’s
location by using a 3D immersive VR power wall. Wang et al. (2018) concluded that immersive VR was important for improving
concentration and giving trainees a measure of control over the environment. Building information modeling VR has been applied in
construction engineering to visualize schedule information and construction work on site, enabling students to interact with building
elements in a VR environment, and a system that includes a question-and-answer game to enhance the learning experience. The
authors found that VR applications are mostly used in architectural visualization and design education, construction safety training,
equipment and operational task training, and structural analysis education. In addition, Wang et al. (2018) revealed five future
directions for VR-related education in construction engineering:
Integrations with emerging education paradigms,
Improvement of VR-related educational kits,
VR-enhanced online education,
Hybrid visualization approaches for ubiquitous learning activities, and
Rapid as-built scene generation for virtual training.
Chavez and Bayona (2018) looked at VR in the learning context and examined the characteristics that determine successful
implementation of this technology as well as its positive effects on learning outcomes. The authors defined 24 characteristics of
VR—e.g., interactive capability, immersion interfaces, animation routines, movement, and simulated virtual environment. They
discovered that, in certain subjects such as medicine, the ‘‘movement’’ feature is vital for learning about the reaction of a person’s
body, whereas, in general education, the ‘‘immersion interfaces’’ are often used as a way to learn through ‘‘live experience’’ that is
closer to reality. The authors further specified 17 positive effects of VR, including improving learning outcomes, living experiences
that are closer to reality, intrinsic motivation, increasing level of interest in learning, and improved skills, although in some fields,
such as psychology, no meaningful learning effects were observed.
To some extent, there are similarities between this work and our work; however, clear differences can be identified. First, we
specifically focus on immersive HMDs as recent technology developments, while Chavez and Bayona (2018) did not distinguish
between immersive and non-immersive VR. Second, we use a systematic mapping method to reveal what VR design elements have
been used for teaching different types of learning content, such as declarative knowledge or procedural and practical knowledge.
In contrast, Chavez and Bayona (2018) analyzed the characteristics of VR applications on a more abstract level and mapped these
using broad application domains such as medicine or psychology.
Suh and Prophet (2018) discussed the state of immersive VR research in their systematic study and, in particular, named current
research trends, major theoretical foundations, and research methods used in previous immersive technology research. Regarding
research trends, Suh and Prophet (2018) found four popular domains that use immersive technologies: education, entertainment,
healthcare, and marketing. They also identified two main research streams. First, studies that examine the user experience and the
effects of unique system features of immersive technology. Second, research that scrutinizes how the use of immersive technologies
enhances user performance through, for instance, learning and teaching effectiveness, task performance, and pain management.
With respect to the theoretical foundations employed in existing immersive technology studies, these authors further identified
the flow theory, conceptual blending theory, cognitive load theory, constructive learning theory, experiential theory, motivation
theory, presence theory, situated cognitive theory, media richness theory, stimulus–organism–response model, and the technology
acceptance model. In terms of the research method, experiments, surveys, and multi-method approaches were frequently used. Suh
and Prophet (2018) provided the following classification framework for immersive technology use:
Stimuli aspect (i.e., sensory, perceptual, and content),
Organism aspect (i.e., cognitive and affective reactions),
Response aspect (i.e., positive and negative outcomes), and
Individual differences in VR use (i.e., gender, age, sensation-seeking tendency, and personal innovativeness).
Jensen and Konradsen (2018) reviewed the use of HMDs in education and training for skill acquisition. The authors examined
factors influencing immersion and presence for applying VR for education, the influence of immersion and presence on learning, and
situations where HMDs are useful for cognitive, psychomotor and affective skills acquisition. They also studied physical discomfort
due to HMD usage and learners’ attitudes toward HMDs. The authors stressed the importance of the content, e.g. simulations as
learning enablers rather than the HMD itself. Some barriers of using HMDs in education and training were identified, i.e. lack of
content and the designs of the HMDs which are more entertainment-oriented than education-oriented. To be relevant for teachers,
HMDs should possess user content editing capability.

Despite the focus on immersive VR technologies, the study of Jensen and Konradsen (2018) is still different from ours in several
points: First, the work does not analyze immersive VR applications in terms of learning content, design elements, underlying learning
theories, and the VR application domains. Second, the findings are limited to declarative knowledge, gesture skills, and emotional
control while our study considers other types of learning outcomes as well.
Merchant et al. (2014) conducted a meta-analysis to address the impact of instructional design principles for VR-based
instructions. They pointed out improved learning outcomes through games compared to simulations and virtual worlds, but there
was an inverse relationship between the number of treatment sessions and learning outcome gains. On the contrary, virtual worlds
deteriorate students’ learning outcome gains. In simulation studies, the elaborated explanation feedback type is more suitable for
declarative tasks whereas knowledge of the correct response is more appropriate for procedural tasks.
We identified distinct contributions compared to our study. First, the review looks at both K-12 and higher education settings.
Second, it examines desktop VR technologies that are excluded in our study. Third, the authors examined the suitability of particular
VR instruction designs for certain learning outcomes. In other words, our study will be complimentary with the findings of the work
of Merchant et al. (2014).
The aspects covered in systematic reviews are summarized in Table 1.
3.2. Gaps in the systematic review of VR for education literature
In order to make a contribution to theory, our study aims to fill gaps in existing literature.
Immersion:Suh and Prophet (2018) focused on immersive VR in their systematic review. However, they also examined several
different application areas besides education, such as health care and marketing. Thus, in this article, immersive VR applications
in the education field were not discussed in-depth. Likewise, the review by Merchant et al. (2014) stresses the learning outcomes.
The review of Feng et al. (2018) only considered serious games as a specific type of immersive VR applications. In contrast, Chavez
and Bayona (2018) did not look at immersive VR in particular but rather examined the characteristics of VR in general. Wang et al.
(2018) discussed immersive VR among other related technologies, such as non-immersive VR (i.e., desktop VR) and augmented
reality. Jensen and Konradsen (2018) do not analyze immersive VR from the perspective of learning content, design elements,
underlying learning theories, and the VR application domains.

RQ9 What is the relationship between learning contents and design elements of immersive VR applications for higher education?
Application areas of VR-based education: While some existing systematic reviews focused on a very specific application area such
as construction engineering (Wang et al.,2018) or evacuation training (Feng et al.,2018), others considered education only as
one application area among many (Suh & Prophet,2018). The work of Chavez and Bayona (2018) provided an overview of VR
application areas in education but can be distinguished from our work through other aspects (i.e., the focus on immersive VR).
Merchant et al. (2014) analyze the literature that is based on the desktop VR technologies.
Overview of teaching content: In addition to the gaps described earlier, all six reviews considered only broad VR application
domains in education (i.e., medicine or psychology) but did not shed light on specific types of learning content that can be taught
using VR applications (e.g., declarative knowledge or procedural and practical knowledge).
Design elements: While Chavez and Bayona (2018) analyzed the characteristics of VR in an educational context on a more abstract
level, the other five reviews did not focus on the design elements underlying the content of HMD-based teaching and education.
Furthermore, a mapping of VR design elements that are used for teaching specific types of learning content is missing thus far.
Merchant et al. (2014) address a single design principle, i.e. instruction design.
Methods and theories:Suh and Prophet (2018) provided an overview of research methods and theories applied in immersive
technologies research but did not particularly focus on education. The other existing reviews focused on entirely different aspects
such as application domains. Thus, an overview of the learning theories that are used as a theoretical foundation for studies on
VR-based learning is still missing.
Evaluation: Little knowledge has been accumulated on how to evaluate learning outcomes when using VR in teaching activities.
While Feng et al. (2018) collected methods for measuring the learning outcomes in the specific application area of evacuation
training, the other existing reviews did not consider learning outcome evaluation methods. Even though the technology being
reviewed was desktop VR, Merchant et al. (2014) discusses the number of treatment sessions and feedback mechanism as factors
affecting the learning outcome. However, the applicability of these treatments for immersive VR needs further examination.
4. Research design
In the following section, we describe our research design, which consists of the method, review process, and classification
framework.
4.1. Research method and research questions
Consensus about the design space of VR-based teaching would significantly aid future developments. To this end, we apply
a systematic mapping approach to the literature by extracting key information from documents indexed in four scientific digital
libraries. Our research aims to obtain an overview of the relationship between application domains and learning contents and
also between design elements and learning contents. Based on our results, we propose an agenda for future research and first
recommendations for the future development of VR applications for higher education.
Systematic literature reviews, as proposed by Kitchenham et al. (2009) or Webster and Watson (2002), have been widely used as
an approach to obtain comprehensive insights into a specific research domain. Furthermore, to answer questions about the structure
of a broad field, relevant topics within this field, as well as research trends, Kitchenham et al. (2009) recommend using a mapping
study, which is a specific form of a systematic literature review. In contrast to a standard systematic literature review, which is
driven by a particular research question, Kitchenham et al. (2009) point out that a mapping study reviews a broader topic and
classifies the primary research papers within the specific domain under study. The research questions suggested in such a study
have a high level of abstraction and include issues such as: what sub-topics have been discussed, what empirical methods have been
used, and what sub-topics have adequate empirical studies to support a more detailed systematic review. An example of applying
the mapping study approach to a literature review is the work of Wendler (2012).
To accomplish the objective of this study, we propose several research questions that focus on systematizing and structuring the
research on VR applications for higher education. They are listed in Table 2.

4.2. Review process and literature search method
Our review process included procedures, considerations, and decisions that lead to a consolidated list of articles to be reviewed
in-depth. We conducted a systematic mapping study, as suggested by Wendler (2012), to obtain an overview of the field. The overall
review process, from defining the review scope to identifying a final selection of articles for analysis, is illustrated in Fig. 1. In total,
the article review process consisted of seven steps.
4.2.1. Definition of the review scope, keywords, and research questions (step 1)
While the research questions have been described in Table 2, defining the scope and keywords was quite challenging because,
in fact, VR research is extensive and the number of publications in this area is abundant. We followed the procedures, as suggested
by Webster and Watson (2002), starting by selecting keyword search strategies in relevant digital libraries. These relevant libraries
for our search were the IEEE Xplore Digital Library, ProQuest, Scopus, and Web of Science. IEEE Xplore is a rich repository that
covers the domains of computer science, information technology, engineering, multimedia, and other software-related publications.
ProQuest comprises articles in the areas of medicine, surgery, and nursing sciences. Scopus provides a wide range of publication
domains, covering the fields of technology, natural sciences, information technologies, social sciences, and medicine. The Web of
Science indexes social science, arts, and humanities spheres. We were aware of other databases, such as the ACM digital library,
Science Direct, JSTOR, EBSCO, and Taylor & Francis, but we expected most of the articles they contain to already be a part of the
databases we selected. This expectation was confirmed by exemplary cross-checks.
4.2.2. Initial paper search in four digital libraries (step 2)
For our database search, we defined the following search string2:
2Appendix A (p. 32) gives the search strings used for each database.
Computers & Education 147 (2020) 103778

J. Radianti et al.
"virtual reality" OR VR
AND educat* OR learn* OR train* OR teach*
AND "higher education" OR university OR college
AND NOT "machine learning" OR "deep learning" OR "artificial intelligence" OR "neural network"
AND NOT rehabilitation OR therapy
Specifying ‘‘higher education’’ OR university OR college was crucial in order to minimize irrelevant application
areas, such as VR for primary, secondary, or vocational education. By adding these keywords, we reduced the results of one
database from more than 3 000 articles to approximately 800 articles. The term NOT (‘‘machine learning’’ OR ‘‘deep
learning’’ OR ‘‘artificial intelligence’’ OR ‘‘neural network’’) was added to avoid articles that reported
on artificial intelligence without the (human) learning context. In addition, the keywords rehabilitation and therapy were
often associated with physical training, which was also out of scope. The exclusion keywords were obtained after conducting several
search tests, followed by a thorough examination of the results.
The search results covered peer-reviewed scientific journal articles and conference papers written in English and published
between 2016 and 2018. A Google Trends search revealed an increasing interest in the topic of VR since 2016, when the immersive
HTC Vive headset was released. Thus, starting the search from 2016 increased the likelihood of obtaining immersive VR-based
learning articles. Due to the novelty of immersive HMDs, the inclusion of conference papers was necessary, as the majority of
innovative research and development using HMDs was being documented in conference papers instead of journal articles. The
aggregated results of the initial search were 3 219 articles. Since we dealt with a considerable number of results, we implemented
a two-stage filtering process: (1) semi-automatic filters for the exclusion and inclusion criteria and (2) manual filters to identify
potential papers.
4.3. Semi-automatic process
Steps 3 and 4 in Fig. 1 were semi-automatic processes created to exclude and include articles by checking and extracting a list
of the most critical words and word clusters from the abstracts. We made use of the list to manually select representative exclusion
and inclusion keywords to narrow down the list of articles to review. The goal of this process was to ensure that the articles about
immersive VR technologies were appropriately captured.
4.3.1. Exclusion and inclusion method (step 3)
First, we performed a content analysis of all databases using KH Coder 3 that can be used for quantitative content analysis, text
mining, and computational linguistic purposes (Coder,2017). To conduct this analysis, pre-processing was performed by removing
punctuation marks, such as periods, commas, and question marks. Stop words (e.g., and, or, of), which provide no additional meaning
to a sentence, were also removed. The words with conjugated or inflected forms, such as verbs or adjectives, were reduced to
their word stems. For instance, buy,bought, and buying, in a given text, would all be extracted as buy. We conducted further pre-
processing by only including nouns, proper-nouns, and verbs in the analysis, while ignoring prepositions, adjectives, and adverbs,
before conducting word clustering.
KH Coder 3 usage was intended for extracting the collections of articles’ abstracts into word clusters and not in order to conduct
complete computational linguistics-based content analysis. The tool provides TermExtract, which is a feature that automatically
extracts clusters of words that often occur together—e.g., ‘‘virtual spatial navigation’’. It could happen that the same word is clustered
into two clusters, such as ‘‘virtual spatial’’ and ‘‘navigation’’, or that unintended cluster of words emerge. However, each word cluster
was scored and, therefore, the highly scored clusters were deemed to be reliable (see Higuchi (2016) for technicalities of KH Coder 3).
Thus, this process is entirely different from simply extracting a frequency word list, where each extracted word is ranked based on
the frequency of its occurrence.
This process returned a list of word clusters with scores and we used the 1 000 most important words and clusters that resulted
from this process to manually select the good enough keywords for additional exclusions and inclusions. This process led to a reduced
selection of potentially relevant articles, which had to be marked as ‘‘relevant’’ and ‘‘not relevant’’ during the subsequent manual
process.
It should be noted that we could have applied more straightforward filtering criteria, such as the number of citations, e.g., to
only review papers that received at least twenty citations. However, this would not have been an ideal approach because we might
have overlooked or excluded interesting, relevant, recent papers due to a small number of citations. It should be recalled that most
collected papers were relatively newly published (between 2016 and 2018).
Second, we went through the list of extracted words and clusters to identify the terms that were useful as additional exclusion
and inclusion criteria. Exemplary exclusion words were ‘‘augmented reality’’ and ‘‘desktop virtual reality’’ because we only focused
on immersive VR and not on augmented or mixed reality. Certain terms, such as ‘‘primary education’’, ‘‘secondary education’’, and
‘‘vocational education’’, were also noticeable exclusion terms because we only focused on higher education. An exhaustive list of
exclusion words is documented in Appendix B (p. 32).
The following inclusion keywords were selected:
vr application, headset, glasses, goggles, immersive, immersion, immers, head-mounted display,
head mounted display, oculus, vive, samsung gear, google cardboard, playstation vr,
playstation virtual reality, pimax, google daydream, samsung odyssey.

Web of Science 112 articles 97 articles 17 articles 12 articles 5 articles
Total 3 219 articles 1 864 articles 590 articles 573 articles 80 articles
These keywords were selected to ensure that our search would return papers that dealt with immersive VR technologies such as
HMDs. It should be noted here that, even though we applied a semi-automatic approach at this stage, we performed quality checks
by skimming the abstracts to check whether the excluded papers were truly irrelevant.
The word extraction and selection was conducted for each database separately because the results from each database varied
significantly. For example, the IEEE database often returned computer science-related articles, while the papers indexed in ProQuest
were mostly related to medicine, health, and nursing sciences. These keyword selections were performed by all authors in order to
agree on the choices of the inclusion and exclusion terms and to clarify if disagreements occurred.
4.3.2. Removing duplicate documents (step 4)
Duplication check was a rather straightforward process. ProQuest, for instance, consists of multiple databases and sometimes
returns two identical articles. By activating ProQuest’s automatic removal feature, redundant results were reduced. In this manner,
28 out of 905 articles were purged from ProQuest so that the number of identified articles was reduced to 877. The duplication
check of the articles across the databases was done using title-based sorting in an Excel spreadsheet. The aggregated results, after
the implementation of the semi-automatic process and duplication removal, were 590 articles, as summarized in Table 3.
4.4. Manual selection process
This process was comprised of three steps—reading the titles and abstracts, reading the contents, and further exclusion of
irrelevant articles.
4.4.1. Manual filter 1: Reading the titles and abstracts (step 5)
In step 5, all authors read through the 590 abstracts obtained from the semi-automatic process, marking the articles as either
relevant or not relevant. To increase the judgment reliability at this stage, each abstract was read by at least two authors. If there
were disagreements, the remaining two authors would also judge the abstracts. This process resulted in 83 articles ready for further
processing. The summary of the papers, from the semi-automatic process to the list of articles ready for thorough reading, can be
seen in the rightmost column of Table 3.
4.4.2. Manual filter 2: Reading the contents (step 6)
This second manual stage not only served as a filtering process but also as a pre-coding stage. As the coding process involved all
authors (four persons), there was a risk that we would code and judge the articles differently. To increase the intercoder reliability
of the coding process and to assure that all paper reviewers worked uniformly, all four authors took part in a coding test with
twenty selected papers. At this stage, we compared the results and discussed discrepancies in the way we coded the articles until
we reached consensus, instead of calculating the discrepancies quantitatively as suggested by Krippendorff (2004)orHolsti (1969).
To help the reviewers judge the category of the paper content in a similar way, we added definitions and explanations for each
concept that were likely to be a subject of multiple interpretations. At this cross-validation stage, the list of ‘‘ready-to-code’’ papers
was already reduced to 80 articles.
4.4.3. Manual filter 3: Further exclusion of irrelevant entries (step 7)
During this stage, we started the actual coding process and continuous reading through all papers allowed irrelevant articles to
be further discarded. We continued practicing the intercoder reliability process in which each paper was coded by two persons. Any
discrepancies were discussed until we had a set of articles with agreed coding categories ready. In the end, we included 38 relevant
articles into our systematic mapping study. They are listed in Appendix C (p. 32).
4.5. Classification framework for analysis
Before beginning the coding process, we developed a concept matrix, as suggested by Webster and Watson (2002), to allow us to
identify the learning contents, application domains, and VR design elements in relation to VR-based education. The analysis followed
five steps, as can be seen in Fig. 2. A slight overlap with the third stage of the manual filtering papers exists, as manual filtering
and coding were performed simultaneously. The concept matrix was a prerequisite to conducting a third manual filtering.

Table 4
Definition of the categories.
Categories Explanation
Empirical, qualitative research A study that adopts well-established qualitative methodology (Creswell & Creswell,2017), such as narrative
research, phenomenology, grounded theory, ethnography, and case studies.
Empirical, quantitative research A study that includes elements such as true experiments, with random assignment of subjects to treatment
conditions, and less rigorous experiments such as quasi-experimental and correlational approaches. This type
of study can also consist of a survey that includes cross-sectional and longitudinal studies using
questionnaires (Creswell & Creswell,2017).
Conceptual A study that is designed with a specific focus on theoretical advancements (Stolterman & Wiberg,2010).
Design-oriented A study that is intended to reveal new knowledge as its primary objective. This is particularly the case if this
knowledge is such that it would not have been attainable if the design – the bringing forth of an artifact
(e.g., a research prototype) – had not been a crucial element of the research process (Fallman,2003).
No method explained A study does not have a recognizable method at all.
4.5.1. Coding
The identified articles, depicted in Fig. 2, were all 80 papers obtained from the second manual filtering. We adapted the concept
matrix used by Webster and Watson (2002), who illustrates it as a logical approach that defines several concepts (e.g., variables,
theories, topics, or methods) that serve as a classification scheme for grouping all relevant articles. Based on existing literature, we
developed an initial concept matrix and added new concepts to it during the classification process.
Traditionally, the systematic literature review process is often done directly on a spreadsheet, including the list of identified
articles and theoretical concepts for analysis. While this method was also considered for this study, we wanted to avoid handling a
large matrix when conducting the coding with several authors at the same time, thus increasing the risk of making errors. Admittedly,
working directly on the spreadsheet has some advantages as well; for example, it would have been easier to make changes when
new concepts were introduced during the coding process.
However, at the same time, working with a spreadsheet can be overwhelming—in our case, 134 concepts were extracted from
the literature. Consequently, as an alternative, we used an online questionnaire that was designed in a way that was consistent with
the concept matrix we developed. Each page of the online questionnaire consisted of one analysis framework with corresponding
concepts. The questionnaire form also enabled us to include the definitions and explanations of each concept, which was helpful to
ensure a unified coding process. We further added an open text field for each framework. In this manner, the coders could propose
new concepts or add notes about their coding decisions. In summary, the method ensured more consistent coding results and made
it easier to work simultaneously during the coding process. Eventually, the results were stored in a single spreadsheet for analysis.
For consolidating the results, we used the classification frameworks as described in Section 4.5.2 to 4.5.5.
4.5.2. Research design framework
We used existing research design categories without proposing new ones. Different authors have different ways of categorizing
research designs, depending on the research perspective being used. Kumar (2019), for instance, divides research based on the study
results’ applications, the objective of the study, and the mode of enquiry used. According to Kumar (2019), research can either be
pure or applied from an application perspective and can be descriptive, exploratory, correlational, or explanatory from a research
objective perspective. From the mode of enquiry perspective, research can either be structured or unstructured. Creswell and Creswell
(2017) divides research designs into qualitative, quantitative, and mixed methods, while Spector and Spector (1981) distinguishes
between experimental and non-experimental research designs. In this study, we adapted the work of Wendler (2012), who classifies
research design into the following categories: empirical qualitative research, empirical quantitative research, conceptual research,
and design-oriented research. The definition of each category is given in Table 4.
4.5.3. Data collection methods and data analysis framework
We combined existing, established data collection methods both in qualitative and quantitative studies with our findings during
the review process. The categories are compiled in Table 5.
The data analysis framework emerged through the coding process, as we extracted only the methods that were explicitly
mentioned by authors. We further added the category of descriptive statistics, which was chosen when authors of the papers from our
search presented their results by reporting frequencies, percentages, means, and standard deviations. The following data analysis
methods were mentioned by the authors: descriptive statistics, t-test, correlation, analysis of variance (ANOVA), chi-square test,
Fisher’s exact test, Mann–Whitney U test, Mc Nemar’s Test, multilevel linear modeling, qualitative analysis technique, and analysis
of co-variance (ANCOVA). If the study did not have recognizable data analysis at all, then ‘‘No Method Applied’’ was chosen.

Table 6
Learning theory framework.
Categories Explanation
Behavioral learning When students receive either rewards or punishments for correct or incorrect answers and can thus learn the
consequences of certain behavior (Shuell,1986;Skinner,1989). This applies to VR applications that include a system
that allows the students to learn—e.g., responses resulting in satisfying (rewarding) consequences or responses
producing annoying (punishing) consequences or learning what the consequences are for following or not following
the rules. The students learn when their responses produce certain outcomes and allow them to adapt to their
environments.
Experiential learning When students learn through hands-on experience and using analytical skills to reflect on their experience (Kolb &
Kolb,2012). These reflections lead to changes in judgment, feelings, or skills of the student.
Generative learning When students engage in cognitive processing during learning, including selecting (i.e., paying attention to relevant
incoming information), organizing (i.e., mentally arranging the information into a coherent structure), and
integrating (i.e., connecting the verbal and pictorial representations with one another and with relevant prior
knowledge activated from long-term memory) (Parong & Mayer,2018).
Operational learning When students learn how to construct or assemble an object—as they do in Zhou, Ji, Xu, and Wang (2018)), where
the students can interact, select, grasp, move, point, and place objects to learn computer assembly.
Game-based learning When students learn through a gamification process, i.e., the use of game design elements and mechanics—such as
points, levels, and badges—and game dynamics—such as rewards, statuses, and competition—in the learning process.
An example of this is found in the work of Bryan, Campbell, and Mangina (2018), where the authors include
gamification in the VR application, allowing the students to travel to different countries around the world, explore
these locations, learn facts, and answer questions.
Contextual learning When students learn by emphasizing the context, i.e., the set of circumstances that are relevant for the learners to
build their knowledge. Hence, the learning content can assist in guiding students toward developing insights through
balanced, organic, and successful environments and strategies. An example of this is a setting in which students use
VR that encourages a more complex and higher level of thinking in order to improve their phonological,
morphological, grammar, and syntax knowledge, as applied by Chen (2016).
Jeffries simulation theory When students learn through a simulation process and experience in a trusted environment that is incorporated in
the VR design (Jeffries, Rodgers, & Adamson,2015).
Cone of learning theory When students learn through both active and passive learning that involves direct, purposeful learning experiences,
such as hands-on or field experience. According to this theory, students learn best when they go through a real
experience or that experience is simulated in a realistic way. This theory is also known as Dale’s Cone theory (Dale,
1969).
4.5.4. Learning framework: Learning theory and learning content
Similar to the data analysis framework, the learning theory framework emerged through the coding process and we only extracted
those learning theories that were explicitly mentioned by authors. Details are given in Table 6. In contrast, Table 7 was first populated
with initial concepts but, then, new categories were gradually established and incorporated into the framework during the coding
process. The first four types of learning content emerged from the literature (cf. with the works of Anderson (1982) and Crebert,
Bates, Bell, Patrick, and Cragnolini (2004)).

Table 7
Learning content framework.
Categories Explanation
Analytical and
problem-solving
Whether the use of VR can encourage students to improve their analytical skills, such as collecting
and analyzing data, writing computer programs, or making complex decisions.
Communication,
collaboration, soft skills
Whether the use of VR is intended to strengthen the students’ ability to work in a team or whether
students can improve their communication skills (e.g., presenting in front of an audience). This
category also includes soft skills, such as management and leadership competencies.
Procedural–practical
knowledge
Where the use of VR aims to assist students with internalizing procedures, such as knowing how to
perform a surgery or how to perform firefighting procedures.
Declarative knowledge Where the use of VR is intended to help students memorize factual knowledge (e.g., theoretical
concepts and scientific principles). This includes, for example, learning the names of planets in our
solar system.
Learning a language Where the use of VR aims to improve students’ foreign language capabilities, such as reading,
listening, writing, and speaking.
Behavioral impacts Where the use of VR aims to change the behavior of students by, for example, improving their
learning habits, awareness of mobbing, and compliance to rules.
Others Articles that could not be classified into the alternative concepts above.
Not specified Where there is no statement or implicit information about the expected learning outcome of VR usage.
4.5.5. Design element framework
As in the learning framework, the design elements of VR for education also emerged from articles during the review process.
Some of the categories had previously been proposed by Wohlgenannt, Fromm, Stieglitz, Radianti, and Majchrzak (2019) but our
work, as listed in Table 8, provides an extensive update.
5. Results and analysis
In the following section, the results of the systematic mapping study are described according to the research questions (see
Table 2, p. 9). Of the 38 articles included in our analysis, 68% originated from conferences, whereas 32% were published in
journals (cf. Fig. 3). Our search window was 2016–2018. However, we also included one paper that was issued in 2015 because
the acceptance for the online publication of this paper was 2015 but the actual journal publication date was in 2016. The number
of journal publications in 2018 was remarkable, indicating an increasing scholarly interest in VR for higher education.
5.1. VR technologies (RQ1: What types of immersive VR technologies are used in higher education?)
As illustrated in Fig. 4, our review shows that 76% of the studies used high-end HMDs, such as Oculus Rift or HTC Vive. Many of
these high-end VR systems use various supporting tools, such as controllers, touchpads, and haptic feedback. Out of 41 VR technology
counts, eight used low-budget mobile VR, for instance, Ye, Hu, Zhou, Lei, and Guan (2018) used a smartphone and Google Cardboard
for the VR environment. However, interactive manipulation was performed through a desktop monitor connected to the mobile app.
Only a few of the articles used enhanced VR, for instance, dela Cruz and Mendoza (2018), Veronez, Gonzaga, Bordin, Kupssinsku,
Kannenberg, Duarte, et al. (2018), and Pena and Ragan (2017). For example, Veronez et al. (2018) used an additional G27 Racing
Wheel to control the VR environment. 2% of the articles did not specifically mention the VR technology employed. It should also
be noted that, in some experiments, two technologies were used, as in Bujdosó, Novac, and Szimkovics (2017), Webster and Dues
(2017) and Buń, Trojanowska, Ivanov, and Pavlenko (2018), leading to a higher count than that of the number of papers. Overall,
high-end HMDs were the most commonly used immersive VR technology.

Table 8
Design element definition.
Categories Explanation
Realistic surroundings The virtual environment is of high graphic quality and has been designed to replicate a specific environment in the
real world. For example, this applies to medical students who develop their surgery skills in an authentic-looking
operation room.
Passive observation Students can look around the virtual environment. This design element also applies to applications in which users
can travel along a predefined path and look around while doing so. However, they are neither able to move around
on their own nor to interact with virtual objects or other users.
Moving around Students can explore the virtual environment on their own by teleporting or flying around.
Basic interaction with objects Students can select virtual objects and interact with them in different ways. This includes retrieving additional
information about an object in written or spoken form, taking and rotating it, zooming in on objects to see more
details, and changing an object’s color or shape.
Assembling objects Students can select virtual objects and put them together, including the creation of new objects by assembling
several individual objects.
Interaction with other users Students can interact with other students or teachers. The interaction can take place in form of an avatar and via
communication tools such as instant messaging or voice chat. This design element also includes the possibility of
students visiting each other’s virtual learning spaces.
Role management The VR application offers different functionalities for different roles. A distinction is made between the role of a
student and the role of a teacher. For a teacher, the VR application offers extended functionalities, such as assigning
and evaluating learning tasks or viewing the learning progress of students.
Screen sharing The VR application allows students and teachers to stream applications and files from their local desktop onto virtual
screens. This allows them to share and edit content from their local desktops with other users in the virtual
environment (e.g., PowerPoint, Google Drive, and Google Docs).
User-generated content Students can create new content, such as 3D models, and upload this new content to the virtual environment. This
design element also applies when the user-generated content can be shared with other users so that they can use it
in their virtual environment as well. This design element does not apply when students can only access virtual
objects that were created by developers and provided by a library in the virtual environment.
Instructions Students have access to a tutorial or to instructions on how to use the VR application and how to perform the
learning tasks. The instructions can be given by text, audio, or a virtual agent. This design element does not apply
when students have to discover how to use the virtual environment or how to perform learning tasks on their own.
Immediate feedback Students receive immediate textual, auditory, or haptic feedback. The feedback informs students about whether they
have solved the learning tasks correctly and whether interactions with virtual objects were successful. In some cases,
feedback may also be provided by simulating the results of an interaction with virtual objects, for example, when the
corresponding chemical reaction is simulated after chemicals have been mixed in a virtual laboratory.
Knowledge test Students can check their learning progress through knowledge tests, quizzes, or challenges.
Virtual rewards Students can receive virtual rewards for successfully completing learning tasks. Students can be rewarded virtually by
receiving achievements, badges, higher ranks on a leader board, and by unlocking exclusive content, such as hidden
rooms or additional learning content.
Making meaningful choices Students learn in the virtual environment through participating in a scenario (role-playing) that can end in different
ways. In this scenario, they have to make decisions that affect the outcome of the scenario. This design element does
not apply when the students’ decisions have no influence on the outcome of the scenario.
5.2. Research designs (RQ2: Which research designs, data collection methods, and data analysis methods are applied to examine the use of
immersive VR in higher education?)
Concerning the research method, development research was popular in 26 articles, as seen in the upper-left bar chart of Fig. 5,
followed by experimental design, usability, and user testing (18 articles) as well as survey (16 articles). The bar chart in the upper-
right of Fig. 5 shows the data analysis method. Both qualitative and quantitative data analysis methods were applied. The t-test
(16) was the most commonly applied quantitative data analysis method. Conversely, other methods were rarely used, in only one
to three articles on average, except for the correlation method (5 articles). However, it was a bit counterintuitive that most papers
had no explicit or recognizable data analysis method (18 articles). Only four papers used qualitative data analysis methods, which
included observations and focus group discussions.
We looked deeper into the relationship between the research design, research method, and data analysis method, as presented
in two bubble charts in the lower part of Fig. 5. It should be noted here that the number of articles in the bubble charts adds up
to a higher number than shown in the bar charts because one article may contain more than one category of research design. The
research design categories in the middle can be read in combination with the bubble charts on the left and the right sides. The
bubble charts depict the concentration of the studies. The combination of the data collection method and the research design is
shown in the bottom left bubble chart of Fig. 5.
It shows that design-oriented, empirical quantitative, and empirical qualitative research were the dominant research contents.
Most of the design-oriented works had combined their studies with development (24 articles), experimental design, usability, and
user testing (11 articles), or had used interviews and focus group discussions to collect data (11 articles). This pattern is similar
to other empirical qualitative and empirical quantitative studies. We discovered very few studies that were designed as conceptual

and these used a development approach (Chin et al.,2017), a literature review (Ekkelenkamp, Koch, de Man, & Kuipers,2016), or
did not mention any data collection method.
The bubble chart on the opposite side shows the combination of research design and data analysis method. Interestingly, most
studies that reported no data analysis methods were design-oriented (16 articles). The majority of studies that employed a design-
oriented research approach primarily reported only descriptive statistics (9 articles). Apart from this, empirical quantitative research
designs employed a wide range of identified data analysis methods, with less visible concentrations. In addition, several of the
empirical qualitative studies reported descriptive statistics as well (4 articles). Furthermore, we identified that this category had
also employed ANOVA, t-test, correlation, multilevel linear modeling, and other quantitative data analysis methods. Four articles
mentioned no explicit data analysis method. Likewise, of the conceptual research design articles, three had not applied any method.
5.3. Learning theories (RQ3: What learning theories are applied to examine the use of immersive VR in higher education?)
Fig. 6 indicates that the literature which claims to create VR content or design VR applications for higher education surprisingly
lacked reference to explicit learning theories. Thus, the ‘‘not mentioned’’ category consists of 68% of all articles. It should also be
noted that, during the coding, we avoided ‘‘reading between the lines’’ and only extracted the learning theories that were explicitly
mentioned by study authors as their theoretical foundation. Among the articles that had a theoretical foundation, experiential
learning accounts for 11% of all articles, while each of the remaining theories accounts for 3%. The other category consists of
an article that explicitly mentions different learning theories, such as the constructivism learning theory, flow theory, gamification
Computers & Education 147 (2020) 103778
16

Fig. 6. Applied learning theories (n=38).
Fig. 7. Evaluation methods.
learning, transfer of learning in the literature review section, but its authors did not really claim which learning theory they prefer
to use (e.g. Chen,2016). The cone of learning theory was kept as a separate category, given the fact that authors explicitly used
this theory in all development VR processes. Recent literature has grouped the cone of learning theory with that of experiential
learning, (e.g., (Garrett,1997)). However, many recent authors are still using this theory on its own (Davis & Summers,2015) and,
therefore, we placed it in a separate category.
5.4. Learning outcome evaluation (RQ4: Which research methods and techniques are applied to evaluate the learning outcomes of immersive
VR usage in higher education?)
Almost half of the reviewed articles did not specify a learning outcome evaluation method (see Fig. 7). A few articles used
questionnaires (22%) or user activities while logged into the VR application (12%). Exams, expert judgments, or focus group
discussions accounted for a mere 5%, respectively, while the remaining articles used observations or sensor data. This fact is
intriguing because many articles described evaluations of developed VR applications, however, the focus was mainly placed on
usability or user experience. Nevertheless, there were also several articles that actually measured or evaluated how much the
students’ knowledge or skills progressed after the use of immersive VR, for example, Farra, Smith, and Ulrich (2018) and Zhang,
Suo, Chen, Liu, and Gao (2017).
5.5. Application domain (RQ5: In what higher education application domains are immersive VR applications used?)
Engineering was the most popular application area identified in 24% of the articles (see Fig. 8). The next most popular application
domains were computer science (10%) and astronomy (7%). The total number adds up to more than 38 articles because we found
several articles that fell into more than one category. Furthermore, some articles were very generic and did not mention a specific
domain (12%). This applied to the works by Hu, Su, and He (2016), Webster and Dues (2017), Yang, Cheng, and Yang (2016), Zizza
et al. (2019), and Misbhauddin (2018).

Fig. 9. Learning content.
5.6. Learning content (RQ6: For which learning contents in higher education are immersive VR applications used?)
Fig. 9 shows that VR applications for higher education were most frequently used to teach: procedural–practical knowledge
(33%), such as filing a report (Pena & Ragan,2017) or extinguishing fires (Zhang et al.,2017); declarative knowledge (25%),
such as learning planet names (Papachristos, Vrellis, & Mikropoulos,2017) or theoretical concepts in pneumatics (dela Cruz &
Mendoza,2018); and analytical and problem-solving skills (12%), such as diagnosing patients (Harrington et al.,2018) or learning
how to code (Román-Ibáñez, Pujol-López, Mora-Mora, Pertegal-Felices, & Jimeno-Morenilla,2018). The rest of the learning content
categories found in the literature were communication, collaboration, and soft skills (10%), behavioral impact (6%), and learning
a language (2%). The categories others and not specified accounted for 6% and 4%.
5.7. Design elements (RQ7: What design elements are included in immersive VR applications for higher education?)
Basic interaction and realistic surroundings were the most frequently used design elements, accounting for 24% and 17% of
the articles, respectively (see Fig. 10). Immediate feedback and instructions share an equal percentage, i.e., 10%. The next popular
element is interaction with other users, which accounted for 9% of all category counts. Passive observation and assembly also
shared an equal percentage of representation at 8% each. The rest of the design elements were included in 1%–4% of all papers,
i.e., moving around (4%), user-generated content (3%), virtual rewards (2%), role management (2%), and knowledge test (2%).
Both screen sharing and making meaningful choices accounted for 1% of all papers.
5.8. Mapping 1 (RQ8: What is the relationship between application domains and learning contents of immersive VR applications for higher
education?)
The bubble chart in Fig. 11 links learning contents and application domains. The magnitude of the bubble corresponds to the
number of articles found for a given combination. The number of articles was too small to generate clusters and such clustering
would also be limited by the fact that application domains are not necessarily independent. Nevertheless, the mapping allowed for
observations, although we could not generalize the relationships between the learning content and the application domain because

18
J. Radianti et al.
Fig. 10. Identified design elements.
Fig. 11. Relationship between learning content and application domain.
too few relevant papers would be included. At the same time, learning contents were spread among application domains, indicating
a wide variety of learning contents across disciplines.
The matrix in Fig. 11 is relatively sparse. While this, undoubtedly, can partly be explained by our attempt at making clear
distinctions, it also hints at the experimental nature of the field. Moreover, we observed that no reasonable grouping of application
domains – for example, biology, chemistry, and physics as natural sciences – would yield additional insights.
From the mapping, we observed that astronomy used either declarative knowledge (Němec, Fasuga, Trubač, & Kratochvíl,2017;
Rosenfield et al.,2018;Veronez et al.,2018) or ‘‘others’’, which included learning content for visualization and motivation. Both
biology and chemistry paid attention to declarative knowledge and procedural or practical knowledge (e.g., the articles by AlAwadhi
et al. (2017), Parong and Mayer (2018)). Since engineering is an application domain frequently described in the literature, it allowed
for a diverse assessment. Engineering used the following learning contents: analytical and problem solving (Harrington et al.,2018;
Parong & Mayer,2018), communication and collaboration or soft skills (Hickman & Akdere,2018;Ye et al.,2018), procedural and
practical knowledge (AlAwadhi et al.,2017;Buń et al.,2018;dela Cruz & Mendoza,2018;Román-Ibáñez et al.,2018;Schroeder,
Bailey, Johnson, & Gonzalez-Holland,2017), and declarative knowledge (AlAwadhi et al.,2017;Němec et al.,2017;Ye et al.,2018).
The only manufacturing article we identified described behavioral impacts (Carruth,2017).
Nursing (Farra et al.,2018;Smith et al.,2018), physics (Pirker, Lesjak, & Guetl,2017), and surgical medicine (Ekkelenkamp
et al.,2016) mainly focused on procedural knowledge. The articles on geography proposed an application to improve declarative
knowledge (Bryan et al.,2018;Parong & Mayer,2018). Similarly, for safety (Zhang et al.,2017), surgical medicine (Harrington et al.,
2018), earth science (Chin et al.,2017;Gerloni et al.,2018), and architecture (Němec et al.,2017), articles describing declarative
knowledge as the learning content could be identified, among diverse other aims. Not surprisingly, the only article we identified in
the domain of language focused on teaching the skill of language learning (Chen,2016).
Diverse pictures can be drawn for computer science and art. Art papers (Cortiz & Silva,2017;Song & Li,2018) varied in terms of
learning content, as did the computer science articles. However, they emphased collaboration and communication (Bujdosó et al.,
2017;Hickman & Akdere,2018) as well as procedural and practical knowledge (Parmar, Isaac, Babu, D’Souza, Leonard, Jörg,
Gundersen, & Daily,2016;Zhou et al.,2018).

5.9. Mapping 2 (RQ9: What is the relationship between learning contents and design elements of immersive VR applications for higher
education?)
Fig. 12 illustrates the overall mapping results of design elements and learning contents. In this way, we analyzed whether there
were patterns of certain design elements that were used in VR applications intended to teach specific learning contents. From Fig. 12,
we can conclude that basic interaction and realistic surroundings were used for each type of learning content. These tendencies
can be observed in the distribution of the bubbles spreading across all learning content categories. However, this observation is
reasonable because most VR applications would need to have at least basic interaction elements and to be realistic enough to
increase the immersive experience of users.
From the design element perspective, the basic interaction element was mostly applied in the procedural or practical knowledge-
oriented VR applications (10 articles) (AlAwadhi et al.,2017;Buń et al.,2018;dela Cruz & Mendoza,2018;Farra et al.,2018;
Harrington et al.,2018;Ibanez, Kloos, Leony, Rueda, & Maroto,2011;Pena & Ragan,2017;Pirker et al.,2017;Smith et al.,2018;
Zhang et al.,2017) and in the declarative knowledge-oriented VR applications (8 articles) (AlAwadhi et al.,2017;Bryan et al.,2018;
Dolezal, Chmelik, & Liarokapis,2017;Hu et al.,2016;Im, An, Kwon, & Kim,2017;Němec et al.,2017;Rosenfield et al.,2018;
Zhang et al.,2017). Likewise, the realistic-surroundings element was adopted for teaching procedural or practical knowledge and
declarative knowledge contents. There were six articles in the former category (AlAwadhi et al.,2017;Buń et al.,2018;Ekkelenkamp
et al.,2016;Im et al.,2017;Smith et al.,2018;Zhang et al.,2017) and six articles the latter category (AlAwadhi et al.,2017;Chin
et al.,2017;Němec et al.,2017;Rosenfield et al.,2018;Ye et al.,2018;Zhang et al.,2017).
Furthermore, from the learning content perspective, seven or more design elements were applied by VR applications intending to
teach the following learning contents: communication, collaboration, and soft skills (11 elements), procedural or practical knowledge
(10 elements), declarative knowledge (9 elements), and analytical and problem solving skills (7 elements). The remaining categories
used four or fewer design elements. On average, an article addressed one to five design elements. Hence, the total number of
design elements per category could be higher than the number of articles. For instance, basic interaction and immediate feedback
elements were identified in the study of Román-Ibáñez et al. (2018). Six design elements were recognized in the article by Dolezal
et al. (2017)—basic interaction, interaction with users, immediate feedback, instructions, role management, and moving around.
Zhang et al. (2017) adopted five design elements—basic interaction, immediate feedback, virtual rewards, realistic surrounding,
and knowledge test. The majority of the articles in each category described more than two design elements.
Only a few articles used the following design elements: user-generated content, role management, moving around, knowledge
test, screen sharing, and making a meaningful choice; these are mostly found in articles that contain multiple design elements.
There is no single rule about what design elements are valid for specific learning contents. Basic interaction, in particular, was
found in all, regardless of the learning contents being addressed. AlAwadhi et al. (2017), Rosenfield et al. (2018), Zhang et al.
(2017), and Němec et al. (2017) are examples of articles that aimed for declarative knowledge. Rosenfield et al. (2018) proposed
the Worldwide Telescope 3D application for exploring the planetary surface, elevation maps, orbital path, ephemerides, and solar
systems in a realistic manner. Zhang et al. (2017) built a VR environment for learning related to fire safety – fire type, fire hazard,

20
J. Radianti et al.
fire alarm – and for providing knowledge about various safety evacuation signs in a virtual campus. AlAwadhi et al. (2017) suggested
a VR design in order to conduct experiments, watch pre-recorded lectures, perform a campus tour, and recognize the components
of informative labs. Both papers also contained practical–procedural content, i.e., how to conduct experiments (AlAwadhi et al.,
2017) and how to prevent fire (Zhang et al.,2017). Němec et al. (2017) presented multiple realistic VR environment objects, such
as human skeletons, solar system planets, architecture, machinery rooms, and power plants.
The articles by Smith et al. (2018) and Buń et al. (2018) are examples of studies that aimed at practical–procedural knowledge,
containing both basic interaction and realistic surrounding design elements. Buń et al. (2018) used VR for improving the users’
procedural knowledge regarding assembly operation in a manufacturing activity. The basic interactions could be recognized in the
possibilities given to users to manipulate objects in a realistic manufacturing environment. Smith et al. (2018) applied VR to teach
decontamination skills—e.g., how to pick up a patient’s freshly cut off, contaminated clothing, and place them in a nearby biohazard
bin. It was tailored with a realistic emergency room environment (Smith et al.,2018).
There were several design elements found in the analytical- and problem solving-oriented literature. Román-Ibáñez et al.
(2018) described learning about robotic arm trajectories and collision detection with immediate feedback. Pena and Ragan (2017)
suggested improving the analytical skill of recognizing accidents in an industrial setting by allowing users to move around in a
virtual environment. Harrington et al. (2018) exploited gesture detection to increase the analytical skills used for decision-making
when working with critically injured patients. Gerloni et al. (2018) proposed the ARGO3D platform for learning about geological
information and geohazards, such as the crater of an active volcano, in a realistic environment. The platform allows students to
navigate inside the environment, fly around, and take pictures. Veronez et al. (2018) developed a VR system to teach the analytical
skills necessary for assessing road safety, while Pirker et al. (2017) provided an example of how VR could improve analytical skills
through experimentation in a virtual physics lab.
To improve communication, collaboration, and soft skills, several design elements were implemented in the literature. Bujdosó
et al. (2017) suggested MaxWhere as a VR collaborative arena (ViRCA) for encouraging interactions with other students. In this
example, it is possible to assign tasks to others, generate new content, and work in shared documents. Zizza et al. (2019) suggested
the VRLE platform, involving one instructor and a group of students, to improve social competencies and social interaction. The
users interact with the environment, as well as with instructors and peers, using virtual hands and voices. Ye et al. (2018) used
assembling elements as part of a soft skill to comprehend the control parameters in the automatic control system and to detect
abnormalities of the system.
Cortiz and Silva (2017) used passive observation to learn art history through VR in which students can add more content into the
learning material, such as artwork from a well-known artist. Hickman and Akdere (2018) reported a conceptual work that describes a
possible VR platform for improving intercultural leadership, which included design elements such as passive observation, immediate
feedback, and realistic surroundings.
There were 17 papers identified for improving procedural and practical knowledge. For example, Muller, Panzoli, Galaup,
Lagarrigue, and Jessel (2017) adopted assembling as the main design element to teach the procedure of setting up a tailstock,
palping, and operating machine. An information and instruction set appears in the VR menu as part of its design elements. Im et al.
(2017) used VR for technical training. Misbhauddin (2018) suggested VREdu for providing an immersive lecture, where the platform
incorporates role management elements that allow different access for students and instructors. It was streamed to users using the
chunking method, i.e., a segment of the video was saved, uploaded to the server, and broadcast.
There were 13 papers that sought to improve declarative knowledge. Dolezal et al. (2017) developed a collaborative virtual
environment for geovisualization, where a virtual world is shared by users with avatars through a computer network. This virtual
environment supports role management by providing different user rights to teachers and students. The tutorial was important in
this work, as part of the instruction design element. The immediate feedback element could be recognized in the possibility provided
to the teacher to press a button and reveal the correct and incorrect answers. Zhang et al. (2017) developed fire safety VR with
mostly basic interaction elements. Bryan et al. (2018) introduced Scenic Spheres, which allows students to travel around the world,
learn facts, and get a feeling about local culture.
Only a few articles focused on learning a language, pedagogical impacts, behavioral impacts, other areas (not falling into an
existing category), and areas not specified (having no recognizable learning content). Typically, such works had multiple design
elements. Only one paper proposed learning language content (Chen,2016) and used the realistic surroundings element that captures
a situation to be used to learn morphology, phonology, grammar, and syntax. It also used some basic interaction elements in VR
such as selecting an object.
The articles aiming to change perceptions, attitude, and actions toward certain issues were categorized as having behavioral
impacts learning content. Parmar et al. (2016) introduced Virtual Environment Interaction (VEnvI) for teaching programming,
logic, and computational thinking in combination with dancing. Users can select dance movements and generate pseudo-code as
visual programming. Additionally, they can select drag and drop options for different movements or steps, such as moving forward,
backward, squatting, and jumping, and can also simultaneously see a co-located virtual self-avatar that mimics their own movements,
look around in the virtual world, and experience a high degree of presence. The behavioral impact happened is found in terms of
changing perception toward computer science and computer scientists by highlighting that learning programming could be fun.
Hu et al. (2016) used VR for safety education and environmental protection. The users can collect and classify virtual objects as a
basic interaction element and can receive rewards when they perform correctly as a feedback mechanism. The behavioral impact here
is with respect to improving actions toward environmental protection. Carruth (2017) developed two VR showcases for industrial
applications, such as familiarizing oneself with industrial workspaces, tools, and safety, in a realistic VR environment. Users can
interact with this VR environment by picking up tools, manipulating them, and exploring a full range of physical interactions that
Computers & Education 147 (2020) 103778
21
J. Radianti et al.
represent the assembling element. The behavior changes in this work regard improved awareness of industrial safety and increased
knowledge on the usage of tools in an industrial setting.
The visualization-oriented content (Němec et al.,2017) and motivation content papers (Song & Li,2018) were merged into the
‘‘others’’ category. In addition, a few of the papers did not easily allow us to derive any design elements and learning content (Webster
& Dues,2017;Yang et al.,2016). Hence, these were classified as papers with ‘‘no specific elements’’.
In a final remark to RQ9, we can summarize the common design elements found in the literature, such as basic interaction
and immediate feedback. Typical basic interactions found in the literature were achieved through two levels: first, through user
interactions with the VR hardware (e.g., controllers) and, second, through the user interactions inside the VR environment.
Concerning the user interactions with the VR hardware, the following eight types of design were primarily found in the literature.
First, head movement detection through sensors embedded in the headset was a basic interaction used to obtain an approximation
of the head orientation (Román-Ibáñez et al.,2018) or the addition of a 360camera (AlAwadhi et al.,2017). Second, motion and
infrared sensors were used to transcribe head movements of pitch (up–down), yaw (side to side), and roll (rotational) in order to
allow for orientation within the virtual space (Harrington et al.,2018) and track the user’s position (Gerloni et al.,2018;Im et al.,
2017). Third, pressing-down a touchpad on the controller or clicking on a map to teleport to the desired location (Pena & Ragan,
2017) was used in order to interact with objects, instruments, or text within the VR platform (Harrington et al.,2018). Fourth,
handheld input with thumbsticks (Gerloni et al.,2018), hand-held controllers, and base-stations were used for accurate localization
and tracking of the controllers (Zizza et al.,2019). Fifth, attaching a racing wheel system was used to enable realistic driving, such as
changing gears manually (Veronez et al.,2018). Sixth, integrated realistic haptic of the VR controllers was sometimes accompanied
by a dual-stage trigger with 24 sensors (Pirker et al.,2017;Zhang et al.,2017)—this can be used to track the natural behavior of
users, such as moving forward and backward, squatting, grabbing, and releasing. Seventh, sensor technologies – such as galvanic
skin response, and facial emotion detection – were used to detect emotions (Hickman & Akdere,2018). Eighth, interacting through
one button only was also used (Muller et al.,2017).
With respect to the interaction inside the VR environment, nine capabilities were revealed in the literature. First, the ability
to manipulate objects in various ways—rotation, placement, or moving the objects using a natural virtual hand metaphor (Zizza
et al.,2019). Second, the ability to grab objects, such as stickers that can be put on a map (Dolezal et al.,2017). Third, basic
pause and repeat, customizable voice notes, and recall abilities (Im et al.,2017). Fourth, the ability to select menu, drag, drop, and
look around using a built-in head tracking functionality (Bryan et al.,2018;Song & Li,2018). Fifth, the ability to interact with
language modules. Sixth, the ability to observe objects, such as numerous art exhibitions or artistic design works (Song & Li,2018).
Seventh, the ability to perform experiments, watch pre-recorded lectures, move around the campus, and touch objects (AlAwadhi
et al.,2017). Eighth, the ability to collect and classify virtual objects (Hu et al.,2016), pick up tools, manipulate them, and explore
a full range of physical interactions (Carruth,2017). Ninth, the ability to look around in the environment (Bryan et al.,2018).
Typical immediate feedback often used in the literature was as follows: alert systems (Román-Ibáñez et al.,2018); sounds to
signal an incorrect gear change (Veronez et al.,2018) or the success and failure when conducting technical works (Im et al.,2017);
virtual hands and voices (Zizza et al.,2019); display of the data stream that updates the status of an object (Ye et al.,2018);
provision of immediate feedback to students through controller vibration when selecting an object in a VR environment (Muller
et al.,2017); revealing correct and incorrect answers by pressing a button (Dolezal et al.,2017); receiving scores after answering
a quiz that appears in the VR environment (AlAwadhi et al.,2017) or when a user performs a correct action (Hu et al.,2016); and
multisensory, visual feedback, such as highlights, signs, and haptic feedback, that allow users to ‘‘feel’’ the virtual objects (Carruth,
2017).
6. Discussion
In the following section, we discuss the results by describing implications, suggesting a research agenda, deriving recommenda-
tions, and identifying limitations.
6.1. Implications
The use of the term immersion in connection to VR technology usage has been understood differently. We had to exclude
many papers during our evaluation process due to their incompatible use of this term, which was often applied to non-immersive
technologies. We included a high number of inclusion terms related to immersive technologies, such as Oculus, Vive, Samsung
Gear, Google Cardboard, and Samsung Odyssey, and excluded as many non-immersive technologies as possible, such as 360-degree
videos, Desktop VR, CAVE, and panoramic videos. Unfortunately, there is still ambiguity and non-homogeneous understanding of
the equipment that can be considered as ‘‘immersive technology’’.
Regarding learning theories, three common types of articles were found in the literature. First, those articles that described VR
applications for higher education in detail often did not mention explicit learning theories as their theoretical foundation (68%).
In these articles, the development of the VR applications was described thoroughly but the evaluation focused mainly on usability.
Such described works, therefore, had an experimental character and were reproducible to some degree only, let alone generalizable.
Second, the articles that described VR development in-depth and also mentioned learning theories were often disconnected. For
instance, the authors only evaluated app features or usability but not the learning outcomes. Third, there were articles that
highlighted the underlying theories of educational VR design but did not report on the technical development in detail. As a result,
it was often hard to extract design elements from these papers.
Computers & Education 147 (2020) 103778

J. Radianti et al.
In the 38 reviewed articles, we could identify 18 application domains, indicating that there is an interest in the use of immersive
VR technologies in many different fields, especially in engineering and computer science. However, this impression must be treated
cautiously because most articles did not report experiences with or lessons learned from implementing VR in real university courses.
The majority reported on the development process or explored potential uses of VR-based learning.
In some areas, VR seemed to be mature enough to be used for teaching procedural, practical knowledge and declarative
knowledge. Examples included fire safety, surgery, nursing, and astronomy. In these cases, more professional VR applications were
used and were proven to be appropriate for learning in higher education. However, the majority of articles indicated that VR for
education is still in its experimental stages—prototyping and testing with students.
Few papers evaluated the learning outcomes after applying VR in a specific domain and most of the evaluations that were made
consisted of usability-oriented tests. This is also another indicator of the VR maturity level, which still remains a barrier for its
adoption in regular teaching activities.
As the only design element, basic interactions apparently appear in all types of VR learning content. However, upon a closer look,
authors highlight two different levels of user interactions: (1) interactions that occur inside the VR environment and (2) interactions
with the hardware, such as the exploitation of haptic and sensors in the headset or other physical objects that connect users with
the VR objects. Many papers claim to have created VR for specific purposes in a realistic environment and the element ‘‘realistic
surrounding’’ was found in almost all learning contents. The terminology of realism is still not uniform, however, as some papers
understood realistic surroundings to be a high-fidelity VR environment with complex, high-quality graphics, while for others it could
also mean ‘‘realistic enough’’, in that the user can recognize the environments or the objects, without the creation of objects with
real-world details.
6.2. Research agenda and recommendations
Our literature analysis indicated that the interest in applying immersive VR for educational purposes has increased. At the same
time, a very low maturity of the field needs to be ascertained. Based on the lessons learned, the following research agenda can be
proposed.
First, the theory on VR for educational applications is apparently not advanced enough to allow for a homogeneous usage of
related terms, such as immersion or realism. To mitigate the retarding effect of ambiguity and unclarity, more work is required
that seeks to contribute toward a common understanding. On the basis of articles such as ours, which summarize categorization
frameworks from theory and which seek to classify other works based on sound criteria, a common understanding can be built.
Ultimately, proposing a taxonomy of learning theories and other framing factors for educational VR applications is a future research
task.
Second, future VR development for higher education needs to built on existing experiments (rather than being exploratory
from scratch) and to provide results that allow for generalization. There is no general issue with design-oriented or even mostly
developmental works. However, to make thorough contributions, such works need to take a holistic standpoint. Our work clearly
indicates that a high contribution and impact can be expected from articles that have a sound theoretical foundation (e.g., learning
theories) and technological foundation (e.g., careful selection of design elements) but are also explicit in describing the design and
development process. Admittedly, such interdisciplinary work can be hard to develop. Thus, providing the necessary theoretical
background to build novel educational VR applications is a future research task. Several aspects of generalization will be supportive.
Technology generalization is driven by work that is outside of the educational context but can make the design of such applications
much easier. Generalization of learning methods and design elements would help to better the sharing of good practices and to design
new course content more rapidly even outside of the fields in which VR has already worked well. As part of this future research
task, researchers will also need a comprehensive market overview of existing VR applications that support education. Industrial
applications might lead the way to theory building by scientists as well as to the creation of new applications in the educational
context.
Third, such works will also allow for a better adoption of VR in higher education. There is currently little exchange of best
practices related to education-oriented VR—either within or across disciplines. For example, VR applications in the natural sciences
might be more similar to one another than, for example, VR applications in the arts. Thus, the research aim again needs to be
holistic and to include well-evaluated works that intend to extend the body of knowledge rather than to simply report anecdotal
findings. This will also help derive best practices from the few applications in which VR is already being used with very good
learning outcomes.
Fourth, to fulfill the aim of deriving best practices and of describing useful application cases, better evaluation procedures
are needed. It is typical that experimental works place the main focus on usability. However, future educational VR applications
should be more thoroughly evaluated by employing quantitative and qualitative research methods to assess the students’ increase of
knowledge and skills as well as the students’ learning experience. Evaluations of educational VR applications need to be conducted
both in terms of technical feasibility (i.e., from a software engineering standpoint) and of the learning outcomes (i.e., from a
pedagogical standpoint). We also suggest that future evaluations assess whether developed applications reflect the users’ needs, from
the perspective of both teachers and students. Thus, future research needs to include workshops, surveys, and focus group discussions
in order to extract the necessary learning content and the expected learning outcomes as well as the usability requirements for VR
applications from teachers and students.
Fifth, technological progress is needed to create environments that are perceived as realistic, thus providing real immersion. This
research aim is not bound to the realm of education. In fact, education can build on high-paced developments, e.g., with respect to
gaming, which leads to better development frameworks and fosters the understanding of how to create immersion.

Sixth, the eventual aim might be an inclusion of VR into higher education curricula. Such an inclusion could be twofold: (1) VR
could be utilized as a teaching tool in real university courses to improve learning outcomes and (2) VR could become the teaching
subject itself. The latter would cater to VR becoming more important for application in more and more professional domains. For
the inclusion of VR in curricula, much more work is needed on the role of the design elements and the design of learning contents
for VR.
6.3. Recommendations for lecturers
Our research shows that the ‘‘realistic surroundings’’ and ‘‘basic interaction’’ design elements occur in all types of VR applications
in our sample. Thus, these can be seen as the basic design requirements for educational VR applications. VR applications that aim
to improve declarative knowledge can be recommended for initiating VR in the courses. In our mapping of design elements and
learning outcomes, we can see that most applications for declarative knowledge use only these two basic design elements. Therefore,
these elements can be a soft start for VR development, easy to use by lecturers and students, and might not require any changes in
the curriculum. In many study programs, students are mainly taught declarative knowledge in lectures and are expected to memorize
what they have learned for exams. The use of VR applications to impart declarative knowledge could support this learning method
to make lectures more exciting.
From our own experience as lecturers, we recognize the students’ wishes on practice-oriented learning contents rather than
memorizing facts. If lecturers have already had good experiences with VR in their lectures, they could use advanced applications
to make teaching more practice-oriented. In our sample, most articles describe VR applications for teaching procedural knowledge.
At the same time, our mapping of design elements and learning outcomes shows that these applications have the largest number
of design elements. This means that the development of such applications is more complex and that teachers and students might
need more VR experience to apply them. Furthermore, it might require complex changes of the curriculum to shift the focus from
teaching declarative knowledge to more practice-oriented content. Nevertheless, we believe that the true potential of VR lies not in
better teaching of declarative knowledge, but in offering opportunities to ‘‘learn by doing’’ which is often very difficult to implement
in traditional lectures.
We have limited results concerning VR aims at improving communication, collaboration and soft skills, behavioral impacts and
analytical skills to be able to derive recommendations for the most useful design elements that will meet specific learning goals.
Revisiting our findings and the research agenda, we conclude that the state of the art does not allow for the provision of an
exhaustive set of recommendations or even a catalogue of best practices. Nonetheless, it is possible to propose an initial list of ideas
for teachers in higher education. It should help them decide when to use VR, for which purposes to use it, and which technological
steps to take.
Undoubtedly, VR is a hyped topic that does not only tend to make technological enthusiasts excited. This momentum can be
used by educators and chances are good for someone to be an early adopter and to make a contribution. Thus, our recommendation
to interested educators is not to be too shy about applying VR to their curricula. They should also be empowered to become
capable of deciding on buying apps, cooperating with the industry, and developing requirements—it does not seem realistic that
non-technologists will be able to develop arbitrary virtual worlds from scratch in the near future.
Since VR applications exist in some fields, it makes much sense to learn from existing good cases. Even without a body of best
practices, solid cases can be used as an indicator of what works. Solid in this sense could mean that a VR application in higher
education is built with sound technology, is explicit about learning aims and design elements, and has been evaluated thoroughly.
Thus, we recommend that such works are built on and that attempts are made to transfer positive experiences as far as possible to
their own application domain.
There are many technological hurdles. The price tag of VR can be very high—maybe too high to be convincing, as long as a
positive impact on learning is not proven. Thus, we recommend starting with a realistically small scope and tailoring the application
case to what seems feasible and achievable in a timespan of a few months. Setting out to virtualize a whole course with all its assets
is bound to fail even if plentiful resources (e.g., funding and VR-proficient personnel) are available. However, the integration of
low-budget mobile HMDs or the use of VR applications in a few selected lecture units over the entire semester could represent first
steps toward a broad adoption of VR in higher education.
6.4. Limitations
Due to the nature of the review, selection, and filtering process, our work has several limitations. First, we only looked at
immersive VR applications for education. There are various VR technologies, other than HMDs, that have been used for educational
purposes, such as 360-degree videos, desktop VR, and mixed reality. These technologies might already have achieved a higher level
of maturity and have been successfully applied for higher education purposes. It is worth acknowledging that as the focus of this
study has been on learning through HMDs VR engagement, the paper does not consider emerging applications and studies applying
collaborative and group engagement in VR through VR domes/other multiple person VR environments (Grogorick, Ueberheide,
Tauscher, Bittner, & Magnor,2019;Liu, Liu, & Jin,2019). Future work might need to seek drawing the whole picture.
Second, we also limited ourselves to publications appearing between 2016 and 2018, assuming this to be a timeline when
HMDs gained popularity and may have changed the way VR is used in the education context. If the types of VR technologies
used in education are not a limiting factor, there are some innovative VR-based teaching and learning approaches that have been

documented by researchers. In other words, the validity of our conclusions is within the scope of the aforementioned research
boundary—despite indications that we have chosen the timescale wisely.
Third, most papers included in this work originated from conference papers instead of journal papers, as part of our definition of
immersive VR was the use of HMDs, regardless of costs. Consequently, some of the papers have not yet reported thorough solutions
or lack supporting theories.
Fourth, this paper does not examine the barriers to the usage of VR for learning, as many papers have reported common issues for
users, such as nausea, dizziness, and some other physical symptoms. Some barriers are related to the technology itself. For example,
the display resolution and cables disturb the immersion in and control of the devices (e.g., grabbing vs. teleporting), making it
difficult to switch functions. In case of mobile VR, the visual system is deemed to be demanding. Sometimes, computational issues
occur during VR experiments that could cause barriers in terms of learning speed. However, technological limitations will gradually
be reduced, along with the emergence of new VR technologies. The 2019 Oculus Quest, for example, comes as a cordless HMD,
which will help to overcome the cable issues. Nonetheless, our work cannot answer the question whether a widespread use of VR
in education is reasonable. None of the named limitations impairs the value of our work; in fact, they provide the opportunity to
continue advancing the field.

literature on educational VR applications were examined. The review results show that the interest in immersive VR technologies
for educational purposes seems to be quite high, which is indicated by the variety of the research domains that have applied this
technology in teaching. The majority of authors treated VR as a promising learning tool for higher education, however, the maturity
of the use of VR in higher education is still questionable. Technologies described in most of the reviewed articles remained in
an experimental state and were mostly tested in terms of their performance and usability. This article also reveals that very few
design-oriented studies constructed their VR applications based on a specific learning theory, which serves as technical development
guidance. Moreover, few papers thoroughly describe how VR-based teaching can be adopted in the teaching curriculum.
These facts can hinder the rapid adoption of immersive VR technologies into teaching on a regular basis. We acknowledge that,
in some domains such as engineering and computer science, certain VR applications have been used on a regular basis to teach
certain skills, especially those that require declarative knowledge and procedural–practical knowledge. However, in most domains,
VR is still experimental and its usage is not systematic or based on best practices. This paper pinpoints key gaps that serve to provide
insights for future improvements, especially for VR application developers and teachers in higher education.
Our work will continue with a market analysis of VR technologies that could be employed in higher education as well with
a survey of educators. We aim to continue advancing the field now that we have understood its low-maturity but nevertheless
promising nature.
