Due to its unsupervised nature, undergraduate education requires students to manage their own learning. They need to use self-regulated learning (SRL) strategies in order to achieve academic success. However, college students often have insufficient regulatory skills and strategies, suggesting the need for substantive and practical support. Supplemental Instruction (SI) is a well-recognized academic intervention that utilizes peer-led study groups for difficult college courses, through which students can develop their SRL abilities.

This study focuses on the role of the SI program in college students’ development of SRL from a person-centered perspective. First, this study examines the heterogeneous effects of the SI intervention on students’ development of SRL by combining latent profile modeling and propensity score matching. Second, it explores the changes in student SRL profiles over the intervention period and determines factors affecting the prediction of such changes using latent transition modeling.

Results identify three distinct student profiles: competent regulator, self-confident regulator, and goal-oriented regulator. Within the competent regulator profile, both SI and non-SI attendees’ overall SRL scores significantly decreased over time, though non-SI attendees showed a greater downturn. For the self-confident regulator profile, only SI attendees’ overall SRL scores increased. Both SI and non-SI attendees in the goal-oriented regulator profile had small decreases in scores, which were not statistically significant.

Regarding students’ longitudinal transitions between SRL profiles, students in the most desirable profile (competent regulator) remained most stable over time. Students’ SRL in the goal-oriented regulator profile was most malleable in a positive way; approximately 40% of these students moved into the competent regulator profile. In addition, students whose decision to attend the SI sessions was more mastery-oriented tended to fall into more positive transition groups. Furthermore, students whose levels of self-confidence in learning, critical thinking skills, and group work skills increased as a result of their participation in SI sessions were more likely to become members of more positive transition groups.

The findings of this study extend previous work by longitudinally examining individual differences in college students’ SRL development. They also provide significant implications for the future design of more targeted interventions.
