A conceptual and practical guide to Teacher Rounds - a powerful form of job-embedded professional development with proven potential to support collaborative learning centered on student learning. It provides detailed examples of teacher rounds in action including a full chapter on a high-performing urban school (University Park Campus School) in which all teachers practice Teacher Rounds in order to foster shared knowledge about teaching and learning, and to develop the kind of learning community for themselves that the teacers value for their students as well.
