Detecting Mistakes in CPR Training with Multimodal Data and Neural Networks

This study investigated to what extent multimodal data can be used to detect mistakes during Cardiopulmonary Resuscitation (CPR) training. We complemented the Laerdal QCPR ResusciAnne manikin with the Multimodal Tutor for CPR, a multi-sensor system consisting of a Microsoft Kinect for tracking body position and a Myo armband for collecting electromyogram information. We collected multimodal data from 11 medical students, each of them performing two sessions of two-minute chest compressions (CCs). We gathered in total 5254 CCs that were all labelled according to five performance indicators, corresponding to common CPR training mistakes. Three out of five indicators, CC rate, CC depth and CC release, were assessed automatically by the ReusciAnne manikin. The remaining two, related to arms and body position, were annotated manually by the research team. We trained five…

Profiling sympathetic arousal in a physics course: How active are students?

Publication

Pijeira-Díaz, H.J., Drachsler, H., Kirschner, P.A. & Järvelä, S. (2018). Profiling sympathetic arousal in a physics course: How active are students? Journal of Computer Assisted Learning Abstract Low arousal states (especially boredom) have been shown to be more deleterious to learning than high arousal states, though the latter have received much more attention (e.g., test anxiety, confusion, and frustration). Aiming at profiling arousal in the classroom (how active students are) and examining how activation levels relate to achievement, we studied sympathetic arousal during two runs of an elective advanced physics course in a real classroom setting, including the course exam. Participants were high school students (N = 24) who were randomly selected from the course population. Arousal was indexed from electrodermal activity, measured unobtrusively via the Empatica E4 wristband. Low arousal was the level…

Read Between the Lines: An Annotation Tool for Multimedia Data for Learning

Open access, Publication

DiMitri, D., Schneider, J., Klemke, R., Specht, M. & Drachsler, H. (2019). Read Between the Lines: An Annotation Tool for Multimodal Data for Learning. In: Proceedings of International Conference on Learning Analytics and Knowledge, Arizona, US, March 7–9, 2019 (LAK ’19). This paper introduces the Visual Inspection Tool (VIT) which supports researchers in the annotation of multimodal data as well as the processing and exploitation for learning purposes. While most of the existing Multimodal Learning Analytics (MMLA) solutions are tailor-made for specific learning tasks and sensors, the VIT addresses the data annotation for different types of learning tasks that can be captured with a customisable set of sensors in a flexible way. The VIT supports MMLA researchers in 1) triangulating multimodal data with video recordings; 2) segmenting the multimodal data into…

Von der LAK19 -> LAK20 in Frankfurt, Germany

Conference, Publication, Workshop

Hendrik Drachsler und sein Team sowie Marc Rittberger waren vom 4. bis 8 März mit mehreren Beiträgen auf der neunten International Learning Analytics and Knowledge Conference 2019 (LAK 19, siehe Bild) in Tempe, USA, vertreten. Dazu gehörte zum Beispiel ein umfangreiches, gemeinsam mit Forschenden von der Open University of the Netherlands verfasstes Paper mit dem Titel Read Between the Lines: An Annotation Tool for Multimodal Data for Learning. Die LAK 20 findet übrigens nächstes Jahr vom 23. bis 27. März an der Goethe-Universität statt – mit ausgerichtet von unseren Kolleginnen und Kollegen. The 10th International Learning Analytics and Knowledge Conference will be held at University of Frankfurt, in Germany on March 23–27, 2020.

Sympathetic arousal commonalities and arousal contagion during collaborative learning: How attuned are triad members?

Publication

This article explores the dynamics of collaborative learning in the classroom from the perspective of the commonalities and interdependence in the degree of physiological activation from the sympathetic nervous system (i.e., sympathetic arousal) of group members. Using Empatica E4 wristbands, electrodermal activity—to derive arousal—was measured in 24 high school students working in groups of three (i.e., triads) during two runs of an advanced physics course. The participants met three times a week over six weeks for lessons of 75 min each. Most of the time (≈60–95% of the lesson) the triad members were at different arousal levels, and, when they were on the same level, it was mainly the low arousal (or deactivated) level. Less than 4% of the time were the triad members simultaneously in high arousal. Possible within-triad arousal…
