Embedded in teacher education, this course aims at fostering (prospective) teachers’ professionalism in dealing with teaching and learning videos: future teachers should be enabled to adequately analyze, select, produce and use videos in formal educational settings. Using the approach design thinking and the professional knowledge of educational media that the students have acquired throughout the seminar we encouraged the participants to develop lesson plans in which teaching and learning videos play a central role. By doing that we link theory and practice. Furthermore, we describe the goals and contents of the interdisciplinary seminar as well as its theoretical foundation. The discussion of the strengths and weaknesses of the seminar and an outlook on its further development conclude the paper. **Poster**: https://osf.io/r9t2g/ [1]: https://files.osf.io/v1/resources/tgdfu/providers/osfstorage/603c10c64415750240587388?mode=render
