The Efficacy of Team-Based Learning in Histology

Abstract

Team-Based Learning (TBL) is an instructional strategy in which traditional lectures are replaced with in-class activities that promote group discussion and active learning. Students are expected to master the basic facts and concepts of the subject matter prior to coming to class. We sought to determine whether the knowledge obtained using TBL is comparable to that obtained using traditional lectures, and whether students have a preference for either instructional method. From 2006-2008, the students in a graduate histology course were taught the structure and function of the basic tissues using TBL. Other topics in the course were taught using lectures, so the students experienced both instructional methods. Using the same 59 multiple-choice questions, we tested the students’ knowledge about the basic tissues, and compared the results to those obtained in 2005, when the basic tissue material was taught using lectures. In 2006-2008, the mean ± SD exam performance after TBL (87.5 ± 7.5, n = 32; 83.9 ± 11.1, n = 36; 78.9 ± 13.2, n = 24) was similar to that observed in 2005 after lectures (82.7 ± 12.0, n = 39). When asked to respond to the statement, “I prefer TBL sessions rather than traditional lectures”, 40.4% of the students agreed or strongly agreed, 23.4% disagreed or strongly disagreed, and 36.0% had no opinion (89 of 92 students responding). These results suggest that TBL and lectures produce comparable learning outcomes, at least as measured on a multiple-choice exam, and that students have a mild preference for the TBL format.
