The role of theory in the study of peer collaboration

This special issue illustrates how research on peer collaboration is influenced by different theoretical perspectives. In the first part of this commentary, the role of theory in each article is discussed. The authors use connections among theory, research questions, and study methods to identify how theory affected the work of each group of researchers. They then make the case that the real need lies in the integration of those theories and in the integration of all findings relevant to applied questions of collaborative processing. Following a brief review of relevant theories, the authors demonstrate how a cohesive, integrated theory of group processes can be adopted.
