Abstract
During the co-evaluation of student teacher of trainees’ learning with the associate teacher, several supervisors experience a discomfort with their role, their actions and their posture. For some, this discomfort is due to a lack of continuous training preventing their professional development. By creating a community of practice, we supported the reflection and analysis of student teaching supervision that take place within triads, made up of the trainees’, the associate teacher and the supervisors. Our objective was to study the contributions of this community to their practices. In this article, we first present the problematic. We then present the conceptual framework consisting of experiential learning, professional development and the community of practice. The methodological approach is then explained, followed by data collected by means of semi-directed individual interviews with the supervisors of the community of practice. The results of the reported practice highlight the contributions of the community of practice to the professional development of its members.
