目的 探讨“三明治”教学方法在流行病学教学中的应用效果,旨在提高医学生对流行病学知识的学习效果。 方法 选取天津医科大学2013级五年制预防医学本科学生120名作为研究对象。将这些学生随机分为实验组和对照组,每组60人。实验组采用“三明治”教学方法,对照组采用传统的教学方法。比较2种教学方法对学生学习成绩的影响及学生的认同率。结果 实验组学生平均理论成绩、案例分析成绩、总成绩和教学认同率均高于对照组。结论 “三明治”教学方法优于传统教学方法,应该在流行病学教学中推广。

Objective To investigate the effect of “sandwich” teaching method in epidemiology teaching and improve the learning effect of medical students on epidemiology knowledge.Methods A total of 120 undergraduates of five-year preventive medicine in Tianjin Medical University were selected as the subjects. The students were randomly divided into experimental group and control group. The experimental group adopted the “sandwich” teaching method while the control group adopted the traditional teaching method to compare the influence of the two teaching methods on the students' academic achievement and the students' identity rate.Results The average theoretical scores, the case analysis scores, the total scores and the teaching identity rate were all higher than which in the control group.Conclusions “Sandwich” teaching method is superior to the traditional teaching method, which is a good way to popularize epidemiology teaching.
