Though university education has changed greatly after years of teaching reform and quality education, traditional teaching mode remains popular. To realize students’major role in class activities, we develop a teaching model with group cooperative learning as the core, and classifies students based on Gardner's dimensions of interpersonal communication intelligence, then we select four key ability indicators. We conduct a test on students group’s cooperative learning in C Language course, and make correlation analyses according to grey theory model. Finally, we make relevant suggestions regarding some problems in the group cooperative learning model.
