In a self-study, five Dutch teacher educators carried out their individual studies, while supported by the group of colleagues and by the three facilitators. These facilitators also conducted a self-study of the whole project, particularly focusing on helping and hindering aspects of the facilitation process. In this article, the authors report two of the teacher educators' self-studies, one in the context of foreign language teaching and the other in the context of deepening student teacher reflection. In addition, the authors describe the design and outcomes of the self-study carried out by the facilitators.
