Lecture-based, problem-based, digital problem-based and distance learning on knowledge improvement in medical education: a meta-analysis

Abstract

Problem-based learning (PBL), an educational approach well applied in education, was believed as a deep method that can promote problem solving, and critical thinking. Varies implementation of PBL across different settings were introduced. How to objectively evaluate knowledge effectiveness of PBLs remains a challenge. The present study is aiming to systematically investigate the knowledge improvement between types of PBL in medical education. Our meta-analysis showed that distance learning using digital PBL could be a good alternative to traditional learning in medical education.
