| Abstract: | Cooperative learning is commonly advocated as an effective instructional strategy in classrooms. Years of research support this recommendation. Recently, however, cognitive researchers and theorists suggest that peer group work may possibly enhance concept development and problem solving. The effectiveness of group work, including peer tutoring, cooperative learning, and peer collaboration, may be explained using several theoretical perspectives. Piaget theorized that the importance of peers comes from their ability to share ideas and initiate the equilibration process in individuals. Vygotsky argued that learning takes place in social contexts only to be internalized at a later time. He proposed a “zone of proximal development” to describe the difference between a student's ability to solve a problem alone and with the help of a more knowledgeable person. Researchers focusing on both theoretical positions argue that results support both theories. Additionally, researchers suggest that peer collaboration may enhance concept development and problem solving ability. Recommendations are made for incorporating effective peer learning strategies into instruction. |
