This book focuses on the terms "collaborative learning," "cooperative learning," and "learning community" in which they have been bandied about in American higher education with great frequency and enthusiasm. One primary purpose of this monograph is to provide a more precise delineation of postsecondary practices that are subsumed or assumed to be embraced by the umbrella terms, collaborative learning, cooperative learning, and learning community, and organize these practices into a coherent classification system or taxonomy.
