In response to the recent calls for a residency model for field internships in education, a possible model based on an adaptation of Japanese lesson study is described. Lesson study consists of collaboratively planning, implementing, and discussing lessons after the lesson is taught. Results of a study in which student teachers and cooperating teachers followed a lesson study format for several meetings is briefly shared, including an analysis of the discussion that took place during planning and follow-up meetings. Suggestions and rationale for a more widespread implementation of the model are discussed.
