PBL结合角色扮演教学模式在八年制急诊临床见习中的运用

目的探讨以问题为基础的学习（Problem based learning，PBL）结合角色扮演模式的教学效果。方法60名学生随机分成2组。观察组采用PBL教学，对照组采用传统授课。2组学生通过角色扮演模拟演练，评估两者的实战表现；笔试评价2组学生基础知识的掌握情况；观察组学生接受问卷调查，对教学方法进行反馈。结果笔试成绩2组差异无统计学意义（P〉0．05）；模拟演练中，观察组表现明显优于对照组（P〈0．05）；问卷调查显示学生普遍接受PBL结合角色扮演的教学模式。结论基于急诊的特点，PBL结合角色扮演的教学模式取得良好的教学效果。

Applications of PBL combined with role play teaching method in the clinical teaching of emergency internal medicine

Objective To investigate the application effect of Problem based learning （PBL） combined with role play teaching method in the training of emergency internal medicine. Methods Totally 60 medical students were randomly divided into two groups. The students in the observation group were trained with PBL teaching method while those in control group were trained with traditional teaching method. The practical performances of the students in both groups were evaluated by virtual experience of dealing with patients in the emergency department through the role play teaching method. The grasp of basic knowledge was assessed by writing tests. Finally all the students in the observation group answered a survey about the teaching methods. Results There was no difference in the scores of the basic knowledge test between the two groups （P 〉 0. 05）. The practical ability of the observation group was much better than that of the control group in the role play practice （ P 〈 0.05 ）. Almost all the students in the observation group accept the PBL teaching method. Conclusion PBL combined with role play teaching method is effective based on the characteristics of emergency medicine.
