Objective: How do learning communities influence academic performance in Introductory Psychology? Method: The present research examines the relationship between participation in first-year students learning communities and academic performance across a variety of course requirements (midterms, finals, papers, and class participation) in introductory psychology and, for comparison, sociology courses. Results: Students who took Introductory Psychology as part of a first-year-student learning community outperformed their peers (who took the same course without a learning community) on the first exam of the semester and were less likely to miss assignments but otherwise showed no significant differences on the other course assignments; introductory sociology students part of these communities showed even greater differences in performance that lasted through the end of the semester. Conclusion: First-year students learning communities offers significant albeit limited benefits for student performance in introductory courses in the social sciences. Teaching Implications: Short of institutional efforts to enact programming for first-year learning communities, introductory psychology instructors can attempt to simulate the experience of such communities by promoting a sense of belonging via extra-curricular service or discipline-related activities.
