The aim of this article is to analyze the features of the role of the facilitator in leading post-lesson discussions in lesson study in the contextual conditions of Portugal, identifying points of contact and differences regarding the role of koshi in Japan.
This is a self-study on an experience of the researcher leading a post-lesson discussion. The discussion was video-recorded, transcribed and analyzed based on a model for leading post-lesson discussions.
There are several aspects of the role of facilitator close to that of a koshi, and the leading of a post-lesson discussion is a complex activity that may be carried out in interaction with the participant teachers.
The model for leading post-lesson discussions is a useful tool for facilitators to carry out this activity and to be attentive to the factors and conditions that may influence its success.
This study is original as it addresses the contrast between the roles of the facilitator and the koshi in the post-lesson discussion, an issue that requires clarification for research and practice.
