目的:探讨适宜研究生流行病学课程的教学模式，为改善和提升教学质量提供科学思路和依据。方法:课程按教学进度分三个阶段进行，即传统教学、传统教学+案例讨论、在线理论学习+案例讨论。分别比较三个阶段学生测试成绩的变化，并对学生对各阶段教学方式的倾向性进行问卷调查。结果:214名学生在三个阶段的测试成绩均呈现上升趋势，且差异有统计学意义（n P<0.001）。多数学生更注重知识的系统性和重点知识的讲解，多数学生认为理论知识和案例讨论的教学时间应均衡分配，更多学生选择与专业相关的中文文献作为教学案例，多数学生认为通过案例讨论教学提高了自学和沟通能力。n 结论:研究生流行病学课程教学改革，应进一步推动传统教学与案例讨论有机融合、在线学习作为有力补充的新型模式，并采取有效手段和方式进行考核评价，提高研究生教学质量。“,”Objective:To explore the suitable teaching mode of epidemiology for postgraduates, so as to provide techniques for improving and enhancing the teaching quality.Methods:The course was divided into three stages according to the teaching progress, which was, traditional teaching, traditional teaching and case discussion, online learning and case discussion. The test scores in three stages were compared respectively, and the students\' willingness to teaching methods was investigated by questionnaire.Results:The scores of 214 students showed an upward trend in three stages, and the differences were statistically significant (n P<0.001). Most students paid more attention to the knowledge systematization and important knowledge. Most students proposed that the teaching time between theoretical knowledge and case discussion should be evenly distributed. More students chose Chinese literature related to their major as teaching cases. Most students believed that case discussion improved the skills of self-study and communication.n Conclusion:The epidemiology course for postgraduate should integrate the traditional teaching and case discussion, with online learning as a supplementary, and take effective methods to evaluate, so as to improve the teaching quality of postgraduate.
