Book excerpt: In School-Based Instructional Rounds, Teitel offers detailed case studies of five different models of school-based rounds and investigates critical learning from each. Instructional rounds—one of the most innovative and powerful approaches to improving teaching and learning—has been taken up by districts across the country and around the world. Now Lee Teitel, an originator of this transformative practice, explores one of the most promising ways in which it is being adapted in the field: implementing instructional rounds networks within, rather than across, K–12 schools. In School-Based Instructional Rounds, Teitel offers detailed case studies of five different models of school-based rounds and investigates critical learning from each. Expanding rounds to include teachers, for instance, offers opportunities for a more direct connection to instructional improvement. Other areas of experimentation include increasing the frequency of visits, engaging participants across diverse roles, and modifying the structure or focus of rounds work. School-Based Instructional Rounds represents an invaluable resource for educators involved in instructional rounds. It marks a significant addition to the literature on this evolving practice."
