基于慕课的混合式教学模式在心电图教学中的应用

Application of Blended Teaching Mode Based on MOOC in Electrocardiogram Teaching

目的探索基于慕课的混合式教学模式在心电图教学中的应用效果。方法选择2021年3—7月暨南大学第一临床医学院2018级临床医学专业本科生为研究对象,共91名。在诊断学心电图章节的教学中,采用以心电图慕课为基础的线上自学和线下面授课相结合的混合式教学模式,分析期末心电图理论和阅图考试成绩和问卷结果。结果理论和阅图成绩分别为(21.00±3.89)分和(19.33±4.63)分。理论考试中,一些心电图基础知识的准确率低于50%,仅有50%的学生能识别心室颤动。阅图考试结果显示,大部分图形节律、心率等基本参数的准确率较高,可达90%以上,而心电图结论的准确率均较低。超过75%的学生认为心电图慕课对学习心电图有很大帮助,阅图训练的15个问题可以帮助理清心电图分析思路;83.15%的学生认为基本掌握了心电图分析要点,8.99%的学生是熟练掌握。结论基于慕课的混合式教学模式对学生掌握心电图分析要点很有帮助,学生对心电图基本参数掌握较好,对于异常心电图特征的记忆和分析有待加强。

Objective To explore a blended teaching mode based on MOOC in teaching electrocardiogram(ECG)and analyze its effect.Methods A total of 91 undergraduates majoring in clinical medicine in the First Clinical College of Jinan University from March to July 2021 were selected as the study objects.A blended teaching mode based on MOOC was introduced into the processes of teaching ECG from March to July in 2021.The final examination,ECG interpretation skills test and questionnaire were used to analyze the effect.Results The scores of theories and ECG interpretation skills test were(21.00±3.89)points and(19.33±4.63)points respectively.On the theoretical test,the accuracy about basic knowledge was less than 50%,and 50%of the students identified ventricular fibrillation.The results of ECG interpretation skills test showed that the accuracy of rhythm,heart rate and other basic parameters were higher than 90%in most cases,while the accuracy of conclusion was low.More than 75%of the students thought that MOOC was very helpful in learning ECG,and the 15 questions in ECG interpretation training was helpful for understanding the key points of analysis.83.15%of the students thought they had mastered the main points of ECG interpretation,and 8.99%were proficient.Conclusion The blended teaching mode based on MOOC is very helpful for students to master ECG interpretation skills.The basic parameters of ECG had been mastered well,but abnormal features need to be strengthened in future.
