Valuing Cooperation and Constructive Controversy: A Tribute to David W. Johnson

The International Association of Conflict Management awarded David Johnson the Jeffrey Rubin Theory-to-Practice Award for professional achievement in 2010. To extend this recognition of David, Negotiation and Conflict Management Research invited us to publish this tribute. We begin with Dean Tjosvold's discussion of David's career. Daniel Druckman describes David's research on constructive controversy and team performance. Roger Johnson outlines how David and he laid the foundations of cooperative learning. Karl Smith describes the development of intellectual disagreement to promote decision-making. Cary Roseth shows the persistence and skill needed for David's meta-analyses on the effects of cooperation and competition on learning. Finally, David responds to three questions developed by the contributors.
