The document describes the design of a teacher education program that uses rehearsals to help novice teachers learn ambitious pedagogies. The program pairs a university math methods course with placements in an elementary school, where teachers-in-training plan lessons, rehearse teaching activities, and receive feedback. Rehearsals last 12-15 minutes and allow novices to practice instructional techniques in a supportive environment. The program aims to bridge the gap between learning about teaching and actual classroom practice through structured learning cycles and a focus on core teaching practices.
