Impact of Team-Based Learning Versus Lecture-Based Learning on Chinese Radiology Education: A Scoping Review and Meta-Analysis

This meta-analysis aimed to evaluate the effectiveness of team-based learning in radiology education. Data sources and selection criteria Databases were searched from inception up to August 2019 and included Pubmed, Medline, Embase, China National Knowledge Infrastructure (CNKI), Chinese Wanfang Database, and Chinese VIP. Randomized trials comparing teaching approaches for medical imaging of which provide the outcomes of theoretical scores and/or practical scores were included. Data were extracted independently by two authors and double-checked for accuracy. Outcomes included knowledge scores and practical scores. We pooled data using random-effects meta-analysis. Twelve trials involving 1,371 participants were included. Team-based learning teaching method had positive impacts on theoretical scores compared with the lecture-based learning or traditional teaching method (SMD = 1.07, 95% CI [0.50, 1.63]) and it positively improved skill scores (SMD = 0.68, 95% CI [0.19, 1.17]). Team-based learning could not only improve theoretical and skill scores in medical imaging courses but also encourage students to learn by themselves. Participants believed team-based learning raised their learning interest, team cooperation ability, and interpersonal communication skills. The heterogeneity of the included studies must be noticed and large well-designed and well-conducted trials are urgently needed.
