A student initiative to implement peer-led study groups for a pharmacogenomics course: Evaluation of student performance and perceptions

Introduction: To better elucidate the impact of cooperative learning outside the classroom, a student-initiated research project was conducted to explore the effects of participating in peer-led study groups (PLSGs) on student examination scores and perceptions. Methods: First-year pharmacy students were given the opportunity to participate in weekly PLSGs for a pharmacogenomics course during spring 2016 and spring 2017. Student exam performance was stratified by those who attended vs. those who did not. Optional pre- and post-course surveys examined student perceptions of PLSGs. Results: No significant differences were seen between the attendance groups in spring 2016. In spring 2017, student attendees were significantly more likely to pass two of their six exams (p = .04, p = .0029) and to have higher exam scores on one exam (p = .02) in comparison to non-attendees. Overall exam score averages were significantly different between attendees and non-attendees during spring 2017 (p = .03) but not during spring 2016 (p = .38). Perception surveys indicated students believed participation helped them to demonstrate competency and build confidence. Additionally, students reported they felt more comfortable clarifying questions during the study groups vs. during class time. Conclusions: The impact of study group participation on student exam performance was minimal over the two years of data collection, but there were instances where exam scores were positively impacted. Students perceived value in study group participation even if it did not translate directly to improved exam performance on all exams.
