This book advances the theoretical account that Barbara Rogoff presented in her highly acclaimed book, Apprenticeship in Thinking. Here, Rogoff collaborates with two master teachers from an innovative school in Salt Lake City, Utah, to examine how students, parents, and teachers learn by being engaged together in a community of learners. Building on observations by participants in this school, this book reveals how children and adults learn through participation in activities of mutual interest. The insights will speak to all those interested in how people learn collaboratively and how schools can improve.
