目的:探讨PBL(pmblem—based leaming)教学法在水、电解质和酸碱平衡教学中的应用优势。方法:选取南京医科大学2011级临床医学七年制6个班级的学生.按自然班随机分为实验组(n=79)和对照组(n=78),实验组采用PBL教学模式,对照组采用传统教学模式(LBL).通过调查问卷及课后测试对两种教学模式进行综合评价。结果:实验组理论测试成绩明显优于对照组(p=0.026),调查问卷显示:PBL组在自主学习能力、病例分析能力、团队协作能力以及在掌握理论知识与临床疾病的联系方面均优于LBL组。结论:与LBL教学法相比,PBL教学法在水、电解质和酸碱平衡教学中应用效果更好,优势更明显。
Objective: To investigate the advantage of PBL teaching method in water-electrolyte metabolism and acid-base balance teaching. Method: Choose 6 classes of students from Nanjing medical university and randomly divided into experimental group (n=79) and control group (n=78), the experimental group using PBL teaching method and the control group using traditional LBL teaching method, evaluating these two methods by analyze the average scores of the test and the survey. Results: The average scores of experimental group were higher than that in the control group (p= 0.026). The survey showed that the experimental group was better in autonomous learning, case analysis, teamwork and using the theoretical knowledge and clinical cases than control group. Conclusion: PBL teaching method was much better than LBL in water-electrolyte metabolism and acid-base balance teaching.
