Results: A significant difference was found between the mean scores of the students' satisfaction before and after applying the cooperative method. Also, there was a significant difference between the pre–test scores in the lecture group and the cooperative group (p<0.001), but no significant difference was observed between post-test scores of the two groups (P=0.1).
