PBL教学模式在医学生教育中的有效性研究——基于随机对照试验的meta分析

Effectiveness of Problem-Based Learning(PBL)Teaching Mode in Medical Education A Meta-Analysis of Randomized Controlled Trials

目的:评估PBL在医学教育中的有效性。方法:检索英文电子数据库,包括PubMed、Embase和Cochrane。比较PBL和传统的讲座式学习在医学教育中对学生理论知识、技能和案例分析分数的影响。结果:共纳入10个RCT,总样本量为1673名医学生。PBL教学模式显著提高了学生技能得分,但未提高学生理论知识和案例分析得分。结论:PBL在提高技能方面比传统教学方法更有效。
