中文摘要:
      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。
英文摘要:
      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.
