基于BOPPPS模型的循证医学课程线上线下混合式教学模式探索

Exploration of BOPPPS-based online and offline hybrid teaching model of evidence-based medicine course

循证医学的线上线下混合式教学模式一直处于探索阶段。既往教学偏重课堂中的授课过程,没有将课前、课中和课后的所有课程内容有机结合起来,而利用BOPPPS模型可以实现循证医学教学过程的连贯和完整。本研究结合循证医学的学科特点和教学目标,初步探索设计了一套基于BOPPPS模型的线上线下混合式教学模式,并以"诊断性证据"模块为例介绍其中的教学实施细节;使用提前设计好的问卷,在课前和课后分别对学生进行基线调查和随访调查,对教学模式和教学效果进行评价。调查显示,半数的学生(77/154)更喜欢新的线上线下相结合的混合式教学模式,对BOPPPS各个教学环节普遍接受且满意。与教学前相比,教学后学生的循证医学素养有明显提升(P<0.001),特别对检索文献和评价证据质量能力,以及拓展知识面和临床思维具有重要意义。

The online and offline hybrid teaching model of evidence-based medicine(EBM)is currently in the stage of development.Previous teaching focused on the teaching process in the classroom,and did not organically combine all the course contents before,during,and after class.The BOPPPS model can be used to establish coherence and integrity in the EBM teaching process.Considering the discipline characteristics and teaching objectives of EBM,this study initially explored and designed a BOPPPS-based online and offline hybrid teaching model.Taking the"diagnostic evidence"module as an example,the teaching implementation details were introduced.A pre-designed questionnaire was used to conduct baseline survey and follow-up survey on students before and after class to evaluate the teaching model and effect.The surveys showed that half of the students(77/154)preferred the new online and offline hybrid teaching model of EBM.The students found that all aspects of BOPPPS teaching were generally acceptable and satisfactory.Compared with before teaching,the students'proficiency in EBM was significantly improved after the teaching(P<0.001),particularly in their ability to retrieve literature and evaluate the quality of evidence,which is of great significance for expanding their knowledge and clinical thinking.
