Background and purposeTeam-based learning (TBL) has been successfully applied to multiple healthcare education disciplines. A primary tenet of TBL is the development of solutions leveraging the collective knowledge of a team rather than the individual competency of any one student. In an effort to enhance individual student accountability, an individual verbal defense (IVD) format was implemented in a multi-campus TBL-based pharmacotherapeutics course. The study sought to investigate the use of TBL-IVD embedded within a traditional TBL format on student engagement, teaching style preferences, and exam performance compared to a TBL-only format. Educational activity and settingIn this cross-sectional study, second-year pharmacy students enrolled in a pharmacotherapeutics course during fall 2019 completed an 11-item survey. The survey was designed to assess TBL-IVD on student engagement and teaching style preference. Free-response qualitative feedback was solicited to assess positive-negative themes related to the activity. Aggregate exam performance for community-acquired pneumonia (CAP) related content was compared to historical exam data to assess the impact on student performance. FindingsThe majority of students (72%, n = 54) preferred the TBL-IVD compared to a TBL-only format. Students reported higher engagement with TBL-IVD (84%, n = 63). Correct exam responses for CAP related content were higher in the TBL-IVD group (67% vs. 55%, P < .001). Positive themes included an increased opportunity to defend recommendations verbally and increased interaction with an on-campus faculty member. SummaryThe study demonstrates the addition of IVD can enhance student perceptions, confidence, and performance within a large, multi-campus, TBL-based pharmacotherapeutics course.
