Ang Chen, Ph.D., is professor in the Department of Kinesiology at the University of North Carolina at Greensboro. He is an experienced researcher in child and adolescent motivation for physical activity, learning on physical education, physical activity and physical skills assessment, and program evaluation. Dr. Chen’s studies examine relationships among curriculum, learner motivation, and physical activity outcomes, such as caloric expenditure in physical education. Specifically, he uses motivation theories to develop an innovative physical education curriculum that encourages behavioral change and enhances child and adolescent knowledge about physical activity. His recent research has focused on cognition-and motivation-based intervention on physical activity behavioral change in children and adolescents. Dr. Chen has been a principal investigator and coinvestigator in several federally funded, large-scale, multiyear physical education intervention studies with elementary and middle school students. He has published approximately 60 research articles and delivered more than 90 research presentations at national and international conferences.
