How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Introduction
I am a senior researcher at the Swiss Distance University of Applied Sciences (FFHS). My current research focuses on the potential and limits of technology-enhanced learning. More specifically, I am interested in the intersection of virtual reality and learning analytics, i.e. how to use multisensory data from VR headset to track student's (collaborative) learning behavior and progress.
I also teach statistics, research methods, and virtual reality in blended learning courses.

This research reports on science pre-service teachers' (PSTs) perceptions and attitudes towards a virtual reality classroom, with the rationale being to elaborate on the pedagogical affordances of technology in the micro-teaching practices of PSTs. A purposeful sample of eighty-three pre-service science teachers from a major South African universit...
Objective
The training of dietitians emphasizes the development of strong communication skills. Immersive virtual reality (IVR) has been successfully employed for various healthcare scenarios; however, it is yet understudied in dietetics education. Therefore, we conducted a feasibility study to investigate the usefulness of IVR for the purpose of c...
Although immersive virtual reality (IVR) technology is becoming increasingly accessible, head-mounted displays with eye tracking capability are more costly and therefore rarely used in educational settings outside of research. This is unfortunate, since combining IVR with eye tracking can reveal crucial information about the learners' behavior and...
This study investigated how pre-service teachers perceive and plan to use a virtual reality classroom for science teaching during microteaching practices. The UTAUT 2 model was adopted as the conceptual framework for this study. Data were collected through an online survey from eighty-three pre-service science teachers from a large metropolitan uni...

Procrastination, the irrational delay of tasks, is a common occurrence in online learning. Potential negative consequences include a higher risk of drop-outs, increased stress, and reduced mood. Due to the rise of learning management systems and learning analytics, indicators of such behavior can be detected, enabling predictions of future procrast...
Recent research has produced mixed results regarding the effectiveness of learning in VR. It has been suggested that the rich multisensory input in VR may induce cognitive overload that impedes the learning process. Cognitive load is typically measured by administering questionnaires. Although questionnaires are easily used, they imply the need to...

Head-mounted displays enable social interactions in immersive virtual environments. However, it is yet unclear whether the technology is also suitable for collaborative work between remote group members. Previous research comparing group performance in nonimmersive computer-mediated communication and face-to-face (FtF) interaction yielded inconsist...
Nutritional diseases severely impair the everyday life of affected patients and represent a growing proportion of global disease burden. The diagnosis and treatment of these diseases is mainly provided by trained dietitians. Their profession requires highly developed conversational skills. Immersive virtual reality offers learning environments, whi...
Measuring emotions non-intrusively via affective computing provides a promising source of information for adaptive learning and intelligent tutoring systems. Using 5 non-intrusive, simultaneous measures of emotions, such systems could steadily adapt to students emotional states. One drawback, however, is the lack of evidence on how such modern meas...
This article demonstrates how an adaptive instructional design for a physics module can be realized in a standard learning management system. We implemented a didactic design with physics-specific online exercises that were accompanied by either detailed or non-detailed instructions, depending on the results of the previous task (or a prior knowled...
This study investigated the measurement of students’ emotional
states during a common learning activity, digital reading of
factual texts. The objective was to compare emotional selfreports
with automated facial emotion recognition. The latter
promises non-intrusive measurements of emotions, which could
inform adaptive learning systems. We used an...
The ongoing digitalisation facilitates measuring emotional characteristics of texts (e.g. lexical emotional valence), and emotional face expressions (e.g. facial emotional valence). In this context, a text was lexically analysed with the revised Berlin Af-fective Word List (BAWL-R), and videos of 91 subjects reading this text were analysed with a f...
Broad cognitive difficulties have been reported in patients with peripheral vestibular deficit, especially in the domain of spatial cognition. Processing and manipulating numbers relies on the ability to use the inherent spatial features of numbers. It is thus conceivable that patients with acute peripheral vestibular deficit show impaired numerica...
The goal of this work is to experimentally investigate the influence of screen size on emotions while reading texts with different emotional content. We had 102 college students read three texts with different emotional content (neutral, negative, positive) on three randomly assigned screen sizes (laptop, tablet, smartphone). After each text, the p...
Unilateral peripheral vestibular deficit leads to broad cognitive difficulties and biases in spatial orientation. More specifically, vestibular patients typically show a spatial bias toward their affected ear in the subjective visual vertical, head and trunk orientation, fall tendency, and walking trajectory. By means of a random number generation...
Despite the close interrelation between vestibular and visual processing (e.g., vestibulo-ocular reflex), surprisingly little is known about vestibular function in visually impaired people. In this study, we investigated thresholds of passive whole-body motion discrimination (leftward vs. rightward) in nine visually impaired participants and nine a...
In this study, we compared direction detection thresholds of passive self-motion in the dark between artistic gymnasts and controls. Twenty-four professional female artistic gymnasts (ranging from 7 to 20 years) and age-matched controls were seated on a motion platform and asked to discriminate the direction of angular (yaw, pitch, roll) and linear...
Questions
Question (1)
We are planning an adaptation of the hidden profile paradigm using virtual reality. Among other variables, we would like to assess social presence (i.e., the awareness of relations among the member s in a mediated communication environment). Does anyone know a validated german questionnaire? Preferably of the social presence scale from Kim (2011)... or any other?
Kim, J. (2011). Developing an instrument to measure social presence in distance higher education. British Journal of Educational Technology, 42(5), 763–777. http://doi.org/10.1111/j.1467-8535.2010.01107.x
Any help is much apprechiated. Thank you!
