The aim of this article is to contribute to the understanding of folk high school teachers’ professional development. Forty-three students, during the last part of their folk high school teacher education, video-recorded and viewed their own teaching sessions. Two years later, eight of them were chosen to do the same again, now as working teachers. The collected data from first occasion was in the form of written reflection documents; the second time it was interview transcripts. Ideas from pragmatism and symbolic interactionism were used when analysing the data. The findings showed that the video tool contributed to the teachers’ professional development, by offering them an image of themselves acting in the classroom. This supported a reflective habit, and gave them more confidence. It helped them to develop on their own terms, in relation to the local context, and to ideas associated with Nordic popular education.
