Instructional rounds are a disciplined way for educators to work together to improve a school's instructional core. The practice combines three common elements of improvement: classroom observation, an improvement strategy, and a network. Instructional rounds differ from supervision and evaluation in that people doing rounds learn something themselves. It's not about "fixing" individual teachers. Rather, rounds are about understanding what's happening in classrooms, how we as a system produce those effects, and how we can move closer to producing the learning we want to see. The process of doing rounds involves gathering a group of colleagues who will meet together over time, defining a problem of practice, visiting classrooms in small groups, debriefing after the observation, identifying next levels of work, and building the group's knowledge and skills about that work.
