Past research consistently reveals that "self-efficacy," referring to one's perceived ability to obtain a desired outcome, in academic courses is linked to academic achievement and motivation in those courses. In particular, high self-efficacy in courses is associated with high academic performance, and low self-efficacy in courses is associated with low academic performance. Yet, the relationship is confounded by the fact that some students report lower effort levels in difficult courses. For students who rise above their fears and devote greater effort to learning, their efforts lead to greater self-efficacy and academic performance. Regarding benefits of Greek-letter organization membership in these domains, several researchers found that students in sororities and fraternities do have greater self-efficacy than students who are not members of any sorority or fraternity, but the findings have been mixed with respect to academics. This study explored the questions of whether Greek affiliation helps students academically and whether self-efficacy plays a role in their academic performance. (Contains 1 table.)
