摘要

目的　评价以问题为基础的学习（problem-based learning， PBL）相对于传统教学在医学统计学教学中的应用效果。方法　采用Meta分析方法，通过计算机检索国内有关2种教学法的对照研究。在严格质量评价的基础上，使用RevMan 5.0软件进行分析。结果　共初检出39篇文献，经筛选最终纳入7篇进行Meta分析。结果显示：PBL教学与传统教学相比，两者的教学效果在综合考核及格率上差异无统计学意义[RR=1.09，95%CI（0.98，1.23），P=0.12>0.05]；在考核成绩分数上差异也无统计学意义[WMD=0.30，95%CI（-0.06， 0.67）， P=0.10>0.05]。结论　尚不能认为PBL教学在医学统计学教学目标的实现上优于传统教学

Abstract

Objective　To evaluate the effect of problem-based learning （PBL） versus tradi-tional methods in medical statistics． Methods　Computer retrieval was conducted to search for con-trolled studies comparing PBL and traditional methods． The quality of included studies was critically evaluated and data were analyzed by using the Cochrane Collaboration's RevMan 5.0 software． Results A total of 21 articles were retrieved， but only 7 were included． The results of Meta analysis showed that there was no significant difference between PBL and traditional methods in both the passing rate of student's score （RR=1.09， 95%CI=0.98-1.23， P=0.12>0.05） and the exact score （WMD=0.30， 95%CI=-0.06 -0.67， P=0.10>0.05）. Conclusion　PBL showed no better learning results in medical statistics compared with traditional methods．
