As he traveled, though, Dintersmith met innovative teachers all across the country -- teachers doing extraordinary things in ordinary settings, creating innovative classrooms where children learn deeply and joyously. Each day, these students are engaged and inspired by their teachers, who in turn help children develop purpose, agency, essential skill sets and mind-sets, and deep knowledge. The insights of these teachers offer a vision of what school could be, and a model for how to help schools achieve it.
