ABSTRACT
The terms peer learning and cooperative learning have been used to describe quite different forms of interactions, with different goals, peer arrangements, and types of activities. In this chapter, we focus specifically on peer learning that is related to collaborative problem solving, typically involving two children. The roots of research on this type of peer learning are not in the field of education, but in developmental psychology, with much of the research occurring in university laboratories or in school, rather than involving the study of group processes in the classroom.
