This study researched 120 college students and professors to test the mediation of group efficacy between perceived autonomy support and self-determinism. The study provided surveys to students in eight different classes. Studying multiple classes offered an opportunity to understand the model more effectively and in a broader scope. The classes studied came from both the humanities and a religious framework. The students and professors took the surveys twice during the semester, during the second week of class and the eighth week of class. This study considered a mediating variable to influence the relationship between perceived autonomy support and self-determinism. Group efficacy was hypothesized to mediate this relationship. Because group efficacy takes time to develop, this study ended up as a minilongitudinal, exploratory study. The results of the study provided validation that group efficacy does not mediate the relationship between perceived autonomy support and self-determinism. However, the study showed there was influence between (a) perceived autonomy support and group efficacy and (b) group efficacy and self-determinism. This provided much discussion. The results assist in understanding learning from a collective nature, which is contrary to Western culture. Future research and discussion of groups as being a stimulating method for learning is necessary to expand this research.
