This study investigates the effects of online video analysis, enhanced by online expert feedback, on preservice teachers’ professional vision of classroom management (PVCM). Preservice teachers composed analyses on videos of other teachers concerning classroom management facets (monitoring/managing momentum/rules and routines). While the control group only analyzed the videos online, the intervention group additionally received online expert feedback on their analyses. The results show that preservice teachers in the intervention group improved their PVCM, while members of the control group showed no significant increases. This study emphasizes the importance of expert feedback during video analysis to foster preservice teachers’ PVCM.
