基于临床案例的PBL教学在组织学与胚胎学教学中的应用研究

Application Research of Problem-Based Learning(PBL)Based on Clinical Cases in Histology and Embryology Teaching

目的:探讨基于临床案例的PBL教学在组织学与胚胎学教学中的应用。方法:选择临床专业2个班级的学生为研究对象,在进行常规面授课程教学外,第一阶段试验组(2016级和2017级临床一系)在自学时间里安排2个临床案例的PBL教学,对照组(2016级和2017级临床二系)利用本校MOOC和精品资源共享课程自学;第二阶段对象为2018级和2019级临床一系和二系,均进行2个临床教案的PBL教学,并开展回顾性问卷调查。结果:第一阶段试验组期末平均成绩优于对照组(P<0.01),第二阶段2018级和2019级成绩无差异(P>0.05)。调查显示PBL教学提高了学生的表达、沟通、自学等能力,加强了与其他学科的联系,有助于后续医学课程的学习。结论:基于临床案例的PBL教学不仅能提高学生的成绩,而且能培养学生高阶学习能力。

Objective:This study explores the application of problem-based learning(PBL)based on clinical cases in histology and embryology teaching.Methods:Two classes of students in clinical majors were selected.In addition to conventional face-to-face teaching,the experimental group in the first phase(Clinical One,2016 and 2017)was provided with 2 clinical case-based PBL sessions during self-study time,while the control group(Clinical Two,2016 and 2017)utilized the university's MO0C and high-quality shared resource courses for self-study.The second phase included students from Clinical One and Two(2018 and 2019),with 2 clinical case-based PBL sessions scheduled during self-study time,followed by a retrospective questionnaire survey.Results:The experimental group in the first phase showed significantly higher final exam scores than the control group(P<0.01),while there was no significant difference in scores in the second phase(P>0.05).The survey indicated that PBL teaching enhanced students'abilities in expression,communication,and self-directed learning,strengthening connections with other disciplines and facilitating subsequent medical course learning.Conclusion:PBL based on clinical cases not only improves students'academic performance but also cultivates their higher-order learning abilities.
