目的 探讨在医学微生物学教学中实施基于案例学习的效果。方法 选取北京协和医学院2016级和2017级八年制临床医学专业共160名学生为研究对象。本研究采用试验对照方法,将2017级86名学生设为试验组,将2016级74名学生设为对照组。试验组采用课堂讲授结合基于案例学习的教学方法,对照组采用传统教学方法。采用期末考试成绩和试验组学生问卷调查结果评估教学效果。结果 试验组和对照组学生期末考试成绩分别为(61.4±3.8)分和(59.7±4.4)分,其差异具有统计学意义(P<0.05)。试验组学生中,90.7% (78/86)的认为基于案例学习有助于促进基础医学知识应用于临床实践,84.9% (73/86)的认为有助于激发学习兴趣或学习动力。结论 基于案例学习能够促进学生加深对所学知识的理解和应用,激发学生的学习兴趣。

Objective To explore the effect of a case-based learning method in the teaching of medical microbiology. Methods One hundred and sixty undergraduates from 8-year program of clinical medicine enrolled in 2016 and 2017 in Peking Union Medical College (PUMC) joined this research. Controlled trial method was applied in the study; 86 students from grade 2017 were assigned to the experimental group and 74 from grade 2016 to the control group. The experimental group was intervened with case-based learning, while traditional teaching was applied in the control group. Final exam analysis of both groups and anonymous questionnaires from the experimental group were used to evaluate the teaching effects. Results The scores of final exam of the experimental group and control group were (61.4±3.8) and (59.7±4.4) respectively(P＜0.05).The new teaching method was thought to be effective facilitation of basic knowledge into clinical use by 90.7%(78/86) students as well as stimulation of students' learning interests by 84.9%(73/86) students. Conclusions Case-based learning can support students' learning, promote the understanding of occupational application of knowledge in future and thus stimulating students' learning interests.
