Because they propose a form of modeling, videos have been recognised to be useful to transfer knowledge about practices requiring teachers to adopt a different role. This paper describes the results of a satisfaction survey with 98 teachers, school administrators and professionals regarding their appreciation of training videos showing teacher-led psychosocial interventions. The association between teachers' appreciation of the video and their desire to implement the intervention are explored in terms of authenticity, vicarious learning and self-efficacy, in an attempt to further comprehend how the use of video supports different aspects of modeling (skills--know-how, attitudes--know-how to be). The authors suggest that training videos featuring teachers leading psychosocial interventions support knowledge transfer because learners can relate to successful peers and can think of themselves as competent to replicate the intervention and comfortable to adopt a different role in the classroom.
