Effects of problem-based learning on delivering medical and nursing education: A systematic review and meta-analysis of randomized controlled trials.

Compared with traditional lecture-based modules, PBL delivered medical education in different medical science specialities more efficiently from both theoretical knowledge and practice skill perspectives. The feedback from participants receiving PBL methods was more positive than that from those receiving traditional methods. However, the high heterogeneity and low quality of the included studies prevented drawing definite conclusions.
