The document discusses the research of brothers Robert and David Johnson on cooperative learning. They established the Cooperative Learning Center to promote cooperative classrooms and teach skills like leadership, communication, and conflict resolution. Students can interact by competing, working individually, or cooperatively with invested interest in each other's learning. Effective cooperative learning involves common goals, individual accountability, idea sharing, social skills, and group processing. Research shows students learn more and have more positive relationships when structured cooperatively rather than competitively or individually.
