We examined the impact of an online- and video-based learning environment on pre-service teachers´ self-efficacy beliefs, their attitudes towards inclusion and their knowledge of inclusive education before and after a teaching practicum. While pre-service teachers in the control group (CG) received a conventional practicum supervision (n = 48), pre-service teachers in the intervention group (IG, n = 41) self-reflected online about challenging situations in teaching inclusive classrooms and received video-based peer feedback. All students had a significant increase of self-efficacy with regard to handling classroom disruptions and improved their knowledge of inclusive education after the teaching practicum. However, there were no differences between students in the CG and the IG. Implications of these finding are discussed.
