Cooperative learning strategies have impacted learning objectives in the cognitive and affective domains in the general classroom and demonstrate quite an impressive history. A number of strategies across subjects and grade levels have proven to be effective in increasing student learning (i.e., achievement tests) and affective or social development (e.g., self-esteem, respect for others). There is little known, however, concerning the effects of cooperative learning strategies in physical education across each of the three learning domains. In this presentation, an in-depth analysis of empirically assessed, cooperative learning strategies specific to physical education will be discussed: Performer and Coach Earn Rewards (PACER) and Jigsaw II in Physical Education (Jigsaw II-PE). Specifically, empirical data will be presented, reflecting what we know works in the name of cooperative learning in physical education.Keyword(s): assessment, professional development, research
