Introduction
Currently, I am the head of the junior research group "Audiovisual Instruction and Information" at the German Institute for Adult Education in Bonn. My research focuses on characteristics of efficient instructional videos and on preconditions for a critical use of informational videos on the internet.

Article
Two complementary studies, one in the laboratory and one in the field, compared the usage patterns and the effectiveness of interactive videos and illustrated textbooks when German secondary school students learned complex content. For this purpose, two videos affording different degrees of interactivity and a content-equivalent illustrated textboo...
Article
We tested whether pauses benefit learning in a longer lasting educational video about acoustic oscillations. Further, we tried to disentangle two explanations for the benefits of pauses. According to the transience explanation, pauses benefit learning because they allow learners to process less information concurrently. According to the structuring...
Article
Two experiments investigated the effects of an instructional video’s setting on learners’ retention and application of the video content. Experiment 1 explored competing hypotheses based on theoretical assumptions about whether an authentic setting would serve as a distraction or as a cue for the instructor’s expertise. Participants (N⫽ 59) watched...

With the recent surge in digitalization across all levels of education, online video platforms gained educational relevance. Therefore, optimizing such platforms in line with learners' actual needs should be considered a priority for scientists and educators alike. In this project, we triangulate logfiles of a large German online video platform for...
Article

Digital images on the internet are often designed to manipulate viewers' interpretations. Therefore, it is important to educate viewers regarding potential effects of such techniques. We investigated whether two interventions addressing potential effects of camera angle affect the technique's effect on participants' power-related judgments of depic...

This study reports a field experiment investigating how instructional videos with and without background music contribute to the learning of examination techniques within a formal curriculum of medical teaching. Following a classroom teaching unit on the techniques for examining the knee and the shoulder joint, our participants (N = 175) rehearsed...
Article

The COVID-19 pandemic poses a health threat that has dominated media coverage. However, not much is known about individual media use to acquire knowledge about COVID-19. To address this open research question, this study investigated how the perceived threat is linked to media use and how media use is associated with perceived and actual knowledge...
Article
Full-text available
In educational contexts, system-determined pauses are often used to interrupt the transient flow of information and thus avoid cognitive overload in dynamic learning materials. However, next to these didactically motivated interruptions, video-based learning materials may also be interrupted due to technical issues with regard to constrained bandwi...
Preprint
This study reports a field experiment investigating how instructional videos with and without background music contribute to the learning of examination techniques within a formal curriculum of medical teaching. Following a classroom teaching unit on the techniques for examining the knee and the shoulder joint, our participants (N = 175) rehearsed...

Lay description What is already known about this topic When learning with written text and static pictures (i.e., multimedia materials), learners map what they read in the text to what they see in the picture. Empirical evidence for the integration of written text and static pictures was generated in studies presenting contradictory text‐picture i...
Article
Job applicants’ self-presentation in their profiles on professional networking services (PNS), such as LinkedIn, may be crucial for the evaluation of their expertise for a job. Importantly, on PNS profiles, self-generated picture-based and text-based cues are shown together, and both may influence expertise evaluations. In three experiments, we sys...
Article
When processing information from multiple documents about a controversial topic, it is important to consider information about the respective documents’ sources. In two experiments, we investigated whether different ways of providing source information affects learners’ use of source information when trying to make sense of a controversy. Experimen...
Chapter
Der vorliegende Beitrag beschäftigt sich nach einer kritischen Würdigung der grundsätzlichen Eignung von Bewegtbildern für den Wissenserwerb mit deren sinnvollem Einsatz in Lernsituationen. Ausgehend von kognitionspsychologischen und pädagogisch-psychologischen Forschungsergebnissen werden Strategien vorgestellt, wie Videos und Animationen durch Pr...
Article
Full-text available
Visual narratives communicate event sequences by using different code systems such as pictures and texts. Thus, comprehenders must integrate information from different codalities. This study addressed such cross-codal integration processes by investigating how the codality of bridging-event information (i.e., pictures, text) affects the understandi...
Article
Recent research presented evidence that producing gestures influences learning and knowledge representations. In this study, we investigated whether this beneficial effect of gesturing is increased for procedural learning tasks in that the motor context (i.e. producing gestures) is congruent during the learning and the testing phase. In Experiment...
Article
We investigated whether the characteristics of pictures affect memory for verbal learning materials. In the learning phase, participants watched a slideshow about historical figures that were depicted as more or as less powerful. The slideshow included spoken information that was more prototypical for either powerful or powerless people and thus se...
Article
We investigated whether historical thinking skills as measured with a standardized test are related to performance in a multiple document task. After 111 German 9th graders completed a standardized test of historical thinking skills, they worked through a computer-based learning environment that included eight documents while answering two open-end...
Article
Mobile guides play an increasingly important role in informal learning settings such as museums and exhibitions, supplementing traditional museum tours offered by human interpreters. In order to identify visitors' strategies of assessing information provided by a digital guide, two studies were conducted in a large exhibition on modern German liter...
Article
Zusammenfassung. Durch die zunehmende Verbreitung dynamischer, audiovisueller Medien in digitalen Lernangeboten gewinnt die Erforschung lernförderlicher Einsatzbedingungen von Videos zunehmend an Gewicht. Ausgehend von potentiellen Schwächen des Mediums Video werden aufbauend auf kognitiven Modellen zum kompetenten Umgang mit Informationen verschie...
Article
This study was concerned with identifying prerequisites for the successful use of videos that offer different levels of interactivity. In a homework scenario, 64 ninth graders participated either in a search training demonstrating the efficient use of features facilitating the selection of relevant information or in a control training focusing on t...
Article
Computer-based video environments allow for the implementation of features such as stop, browsing, table of contents, and index that enable the recipients to engage in activities comparable to activities that were shown to be associated with superior performance with text-based learning materials. Whereas the availability of features such as stop a...
