In this study goal orientation theory, a model used to explore achievement motivation that is commonly covered in introductory psychology textbooks, is used to improve student success. Some variants of the theory posit that mastery goals are associated with adaptive behaviours that can lead to increased success. As a result, the authors of this study developed an intervention designed to increase the pursuit of mastery goals. In previous research, they found that the intervention was associated with altered goals and improved grades. In the current study, they examined the consequences for retention and graduation rates. During the fall 2005 semester, the intervention was extended to 221 students enrolled in introductory psychology classes. A similar set of students who did not receive the intervention served as a comparison group. Five years later, the authors examined the students' transcripts for persistence in school. Students who were at risk for failure and who completed the intervention enrolled in courses at the university at nearly twice the rate of the comparison group in each of the subsequent years, and they graduated at nearly twice the rate of the comparison group. Thus, this intervention was associated with increased retention and graduation rates.
