This session addresses the infrastructure that leaders must cultivate to sustain system-wide instructional improvement. With an evergreen aim to reduce variation in the quality of instruction students experience–both within and across classrooms–we will share our approach to shifting how building and district leaders think and act within their systems. Core principles include creating a shared definition of equitable and adaptive instruction, leveling power structures, reversing the flow of feedback, lowering the stakes for engaging in real-time improvement work, providing practical support for collaborative learning through teacher teams, and changing beliefs about teachers, about students, about data, and about improvement.
