PBL教学法在医学本科生医学统计学实验教学中的应用

目的探讨PBL教学法在医学本科生医学统计学实验教学中的应用，以提高医学统计学实验教学质量。方法随机选择我校临床专业本科生1个班级共72人，按小组分为2个实验室，其中1个实验室采取PBL教学法作为PBL组，另1个实验室仍用传统的实验方法作为对照组，观察一个学期，比较两组的教学效果。结果问卷调查结果表明PBL组在很多方面优于对照组，PBL组学生喜欢医学统计学的比例高于对照组（χ^2=5．14，P〈0．05）；PBL组学生认为医学统计学有实用价值的比例高于对照组（χ^2=4．60，P〈0．05）；PBL组学生对实验课内容满意的比例高于对照组（χ^2=4.19，P〈0．05），PBL组学生对实验课形式满意的比例高于对照组（χ^2=6．24，P〈0．05）。结论PBL教学法在医学统计学实验教学中效果显著，能提高医学统计学实验教学质量。

Application of problem-based learning in experimental teaching of medical statistics for medical undergraduates

Objective To study on application of problem-based learning in experimental teaching of medical statistics for medical undergraduates and to improve the quality of experimental teaching in medical statistics. Methods 72 medical undergraduates were selected at random. They were devided into the PBL group and the control group were observed for a term. Results The comparison of a questionnaire showed a clear preference for PBL group over the control group. Most of the constituent ratios in the PBL group were ...
