VorleXung: Combining lecture and exercise in physics through experiment-related video analysis tasks

One of the reasons for the large number of dropouts in the field of physics is seen in the fact that challenging, highly theoretical lectures are not closely linked to the accompanying homework problems and recitation sessions. To establish a substantial connection between lectures and homeworks, VorleXung replaces some of the traditional homeworks problems with experiment-related video analysis tasks. This means that students first see the demonstration of an experiment during the lecture and then examine a video of the same experiment using the video-analysis software “Tracker” in their homework. In this way, physical contents introduced in the lecture, which were passively accepted by the students, should be used actively and with greater depth of processing to solve physical problems. Within the project VorleXung we study the learning outcomes comparing two groups, with and without the use of video-based tasks.
