心电图翻转课堂的教学效果研究

目的　探讨翻转课堂在心电图教学中的效果。方法　以中国医科大学选修心电图课程的2013级临床医学专业106名学生为实验组，2012级临床医学专业107名学生为对照组。实验组采用基于微课程的翻转课堂教学；对照组采用传统教学。课后对两组学生进行统一考试，并对实验组学生进行教学效果问卷调查。应用SPSS 16.0对组间成绩行t检验。结果　实验组学生病例分析考核平均得分为（37.1±6.1），对照组为（28.1±6.7），差异有统计学意义（P=0.000）。实验组学生理论知识考核平均得分为（38.1±5.1），对照组为（37.5±4.4），差异无统计学意义（P=0.402）。实验组学生的问卷有效回收率为100%，其中各项指标满意度均在81.0%以上。结论　在心电图教学中应用翻转课堂，能够提升心电图病例分析教学效果，加强学生心电图综合分析能力。

Study on the teaching effect of ECG flipped classroom

Objective To explore the effect of flipped classroom in ECG teaching. Methods Dur-ing the electrocardiogram elective course of China Medical University, a total of 106 clinical medicine students of Grade 2013 were selected as the experimental group, and 107 clinical medicine students of Grade 2012 were selected as the control group. The experimental group adopted the micro-class-based flipped classroom teaching, while the control group used traditional teaching. At the end of the course, the two groups of students were given a unified examination, and the experimental group students were surveyed. A t-test was performed on the scores between the groups using SPSS 16.0. Results The average score of the students in the experimental group was (37.1±6.1), which was higher than that of the control group (28.1±6.7). The difference was statistically significant (P=0.000). The average score of theoretical knowledge assess-ment was (38.1±5.1) in the experimental group and (37.5±4.4) in the control group. The difference was not statistically significant (P=0.402). The effective recovery rate of the questionnaire in the experimental group was 100%, and the satisfaction of each item was above 81.0%. Conclusion The application of flipped classroom in ECG teaching can improve the teaching effect of ECG case analysis and strengthen the students'' comprehensive analysis ability of ECG.
