Boundary Crossings: Cooperative Learning, Collaborative Learning, and Problem-Based Learning

Since the 1960s, there has been growing and sustained interest in small-group learning approaches at the school level and in higher education. A voluminous body of literature in this area addresses theory, research, classroom practice, and faculty development. The approaches most highly represented in the literature are cooperative learning, collaborative learning, and problem-based learning (PBL). In this article, the authors compare and contrast these approaches through answering questions such as the following: What are the unique features of each approach? What do the three approaches have in common? How are they similar, and how are they different?
