We developed a hands-on course in molecular biology for undergraduate underrepresented in medicine (URM) students. To incentivize student preparation for team-based learning (TBL) activities, we implemented a novel grading schema that requires a minimum individual readiness assurance test (iRAT) score to share the team group readiness assurance test (gRAT) score. Fifty-one students participated in this 2-year study and were divided in teams of five or six students that worked throughout the course on a unique, hands-on project and also participated in TBL exercises. In the laboratory sessions, students isolated RNA from cultured neuronal cells, synthesized complementary DNA (cDNA), and used gene sequencing to identify a gene relevant in human health and disease. Student participation in TBL was quantified and correlated with performance on individual iRATs and the course final examination. We found that implementation of the novel incentive structure lowered the variance of TBL scores (iRAT and gRAT) and strengthened the correlation between final examination scores and either iRAT scores or percentage participation in TBL. Subgroup analysis showed that with the new grading schema, stronger students benefited more from the gRAT exercises, while more poorly performing students were better helped by individual preparation prior to the iRAT exercise. A combination of two active learning strategies, TBL and hands-on sessions, may strengthen student acquisition of course content and promote teamwork skills. The new incentive structure seems to reduce the disparity in knowledge amongst our students as demonstrated by the reduced iRAT and gRAT score variances.

Objectives: To evaluate the ability of pathology modules to promote learning of pathology-related course content in a preclinical medical education curriculum.Methods: Pathology modules were created for the "Hematology/Oncology" and "Women's Health" (WH) courses. Students were recruited over 2 consecutive academic years; cohorts 1 and 2 refer to 2 separate groups of students in years 1 and 2, respectively, of the study. Course performance data were collected.Results: Use of pathology modules resulted in a statistically significant higher correlation between performance on the final examination and pathology-related questions in the Hematology/Oncology course and written examination and pathology-related questions in cohort 1 in the WH course. There was statistically significant improvement (P = .026) on pathology-related laboratory practical examination questions in the WH course for cohort 1, and no other statistically significant improvement for the other cohorts and examinations. The percentage of students completing all or part of the modules was highest in the WH course for cohort 1 (60%) compared with WH course cohort 2 (33%) and Hematology/Oncology cohort 1 (30%) and cohort 2 (39%).Conclusions: Pathology modules may improve acquisition and retention of pathology-related course content when used appropriately.
