This article describes the research landscape related to the use of video for promoting teacher learning, drawing on a variety of research studies to illustrate the breadth of approaches that have been employed. One particular research study is reported in some detail since, it is argued, this represents a new level of devolution of agency to teachers to play a self-scaffolding role in their own professional education. The study involved the investigation of an approach to the provision of feedback to teachers about their practice that involved stimulating teacher self-reflection and juxtaposed structure and agency. An observation framework grounded in classroom practice research was developed, and teachers selected elements of that framework to serve as the focus for examining their practice and seeking feedback about that practice. Teachers and researchers examined video-recorded lessons focusing on the teachers' selected observation elements, and then engaged in feedback conversations about their observations and analyses, and the implications of these for future practice. The approach identified the video record as an artefact of the teacher's own practice and one which demanded a professional response from the teacher. The balance between structure and agency realised in the study, in combination with the use of video for observation and analysis of practice, facilitated teacher self-reflection and functioned to both support and provoke teacher learning.
