急诊医学教学中两种教学方法实施效果的比较研究

目的 比较以问题为基础学习(problem-based learning,PBL)结合智能化计算机模拟教学与传统的以授课为基础学习(lecture-based learning,LBL)两种教学方法在急诊医学教学中的应用效果.方法 以大连大学医学院2006级五年制临床医学专业1班和2班49名学生为研究对象,1班25名学生为对照组,2班24名学生为实验组.两组学生在年龄、性别、基础文化程度、专业知识掌握等方面差异无统计学意义.针对心肺脑复苏章节的急诊教学,对照组采用LBL教学方法;实验组采用PBL结合智能化计算机模拟教学方法.教学结束后,采用问卷调查、理论及操作技能考核等主客观评价方法共同评价教学效果.结果 与对照组学生比较,实验组学生在教学中能够主动提出问题,积极参与讨论,发言踊跃,课堂气氛活跃.调查结果显示,学生对PBL结合智能化计算机模拟教学方法满意度高于LBL教学方法.比较两组学生的考试成绩,无论是理论测试还是操作技能考核,实验组学生的成绩均明显优于对照组学生(P<0.05).结论 PBL结合智能化计算机模拟教学比LBL教学更能够增加学生学习的兴趣,加深学生对知识的理解和记忆,增进团体协作精神,并且能够更好地培养学生急诊医学思维和解决临床问题的能力,显著提高了急诊医学的教学效果.

Abstract：

Objective To evaluate the application effects of problem-based leaning (PBL) combined with intelligent simulation teaching and lecture-based learning (LBL) in course of cardio-pulmonary-cerebral resuscitation of emergency medicine. Methods Using 49 undergraduate students of grade 2006, five-year clinical medicine in Medical School of Dalian University as the object of research, and class 1 (n=25) for control group, class 2(n=24) for experimental group. The students of control group were taught by traditional LBL teaching method, and experimental group were taught by PBL combined with intelligent computer simulations teaching method. The teaching effect was evaluated by using the results of questionnaire survey and theory examination skills and operating skills together. Results Compared with controls group, the students of experimental group were able to question actively and participate in discussions, spoken enthusiastically, and active atmosphere. The results of students' questionnaires showed that satisfaction of students for PBL combined with intelligent simulation teaching method were better than LBL teaching method. Test scores, either in theory or skills assessment test experimental results are better than control group (P<0.05). Conclusions Compared with traditional LBL teaching method, PBL combined with intelligent simulation teaching method can increase students' interest in learning, deepen understanding and memory of the knowledge, enhance team spirit and bring up ability to emergency medicine clinical thinking and solving practical problems, and improve the teaching effect of emergency medicine greatly.
