PBL教学法在医学微生物学中的应用探索与体会

A study on application of PBL in medical microbiology teaching

在医学微生物学教学改革实践中,对传统讲授式教学与PBL教学进行比较。结果显示PBL法教学组学生的分析题成绩、理论成绩、总成绩均比传统讲授教学组好,差异有高度显著性(P<0.01)。在PBL实践过程中发现影响其教学效果的主要因素有:教师和学生角色转变的困难;学生易受非重要问题的困扰;时间和硬件设备的缺乏;考核方式不完善。由此,提出相应的对策,以获得更好的教学效果。

In the reform of medical microbiology teaching,Problem Based Learning（PBL） was compared to traditional tuitional methods.The result indicated that the PBL group＇s scores of analysis problems,scores of theories and the total scores in examinations were significantly higher（P0.01） than those of the traditional group.In the PBL teaching practice,major factors influencing teaching effect were found as the following： difficulties of role changing between teachers and students,student being easily puzzled by secondary problems,shortage of time and equipments,and defects in assessment methods.Therefore,corresponding countermeasures are provided in the present study to improve the teaching effect.
