The use of video is steadily highlighted as a powerful tool for teachers’ professional learning. The research literature points to a range of different advantages and purposes for using video, and this chapter summarizes research specifically indicating that the use of videos can contribute to developing in-service and pre-service teachers’ professional vision. The chapter shows how the use of video can enable a variety of perspectives on teaching, for instance by focused attention on the students’ perspective. The chapter also outlines research indicating how the use of video can enhance teacher noticing and reflective skills, and finally discusses how video can contribute to an inquiry stance necessary to develop teaching. Throughout the chapter, empirical data is shared to illustrate how teachers pre- and in-service teachers themselves experience using video as a professional tool-and how that has impacted their own professional learning. © 2024 selection and editorial matter, Marte Blikstad-Balas and Inga Staal Jenset; individual chapters, the contributors.
