The research presented in this paper investigates a pre-service teacher's reflection on professional learning using the medium of video. To promote a reflective activity, we invited the pre-service teacher--now a titular teacher--to comment on their activity while remarking on a recording of one of their lessons conducted one year earlier. The lesson was performed in a professional high school, followed by a meeting with the teacher and a university tutor. Quali-quantitative analysis was used to analyse the data--where the teacher's reflections emerged during their viewing of the lesson--to trace the typology of the comments of the pre-service teacher, and the topics of the reflection. The analysis highlights the dimensions of reflective activity, which can be a reflection of the professional learning of the pre-service teacher in one year. This study provides useful information in describing the process of professional learning and, at the same time, supports the integration of video into pre-service teacher training as a tool of reflection.
