标题：Interaktive Videovignetten aus naturwissenschaftlichem Unterricht – Förderung der Diagnosekompetenz von Lehramtsstudierenden hinsichtlich der Experimentierfähigkeit von Schülerinnen und Schülern
摘要：There is empirical evidence showing the acceptance and positive effects of video-based learning (Schrader et al. 2010). Yet the requirements for an integration of scientifically sound concepts of video casework into the phases of pre- and in-service teacher training are less well-examined (Digel und Hetfleisch 2013). In the present study, school children experimenting in groups during science classes are filmed. Out of the material, video vignettes are extracted, which then are employed in master courses at the university. These are made available for individual use in an online learning management system as well. The students watch, describe, and analyse the scenes using Event-Sampling, and develop possible solutions to the situations or approaches at alternatives, applying a category system which is based on the SDDS model (Klahr and Dunbar 1988; Klahr 2000). The students' analyses are compared with experts' ratings. The results show that diagnostic competencies with regard to the experimental problem-solving competency of students can already be initiated during pre-service teacher training at the university. The case-by-case, qualitative evaluation of the learning process analyses shows an increasing range of reflection, which, however, is not yet based on the SDDS model or category system (depth of reflection).
