Blood and Lymphoid Tissue: A Team-Based Learning Module for Histology

Abstract

Abstract Introduction Team-based learning (TBL) is an instructional strategy that promotes greater student engagement in the classroom. In TBL, scheduled class time is not used for lecturing. Rather, students are expected to master the basic facts and concepts of the subject matter before coming to class; in-class time is devoted to applying this knowledge to solve challenging problems with students' teams. This TBL module will enable students to describe the structural and functional characteristics of blood cells, explain the basic organization and cellular composition of the central and peripheral lymphoid tissues, and interpret select clinical data related to the immunology of disease. Methods The module consists of four documents: an instructor's guide, an individual readiness assurance test (iRAT), a group readiness assurance test (gRAT), and a group application exercise. Explanations of correct answers are provided with the iRAT and group application exercise documents. Prior to the TBL session, students are expected to complete an advanced preparation assignment consisting of textbook readings and laboratory work. Results This module has been administered five times to a total of 157 graduate students, with the cumulative mean scores being 79.4% for the iRAT, 96.6% for the gRAT, and 95.7% for the group application exercise, reflecting solid student understanding of the structure and function of blood and lymphoid tissue. Discussion These results show that TBL methodology is an effective strategy to teach graduate-level histology, and that students do not require formal lectures to learn the material. Based on our experience, we believe that TBL offers learning outcomes comparable to lecture-based instruction but with greater clinical relevance.
