In this book, leading experts on teaching and policy research provide concrete illustrations of what teaching for understanding entails. They show how, for example, to foster, sustain, and support the knowledge, capacity, and professional beliefs essential for teachers moving beyond a "teach and test" approach to analytic reflection on classroom life and their relationship with students' learning. And they describe the collegial relations and institutional arrangements that support or inhibit the process of teachers and students working together to develop knowledge.
