医学本科生心电图见习教学方法探索

Exploration of electrocardiogram teaching methods in probationary medical undergraduates

目的探索一种普适性强的本科生心电图高效见习教学方法。方法在有限学时,设计了"两段三步八环节"的见习教学方法,通过课后调查问卷、见习前后读图测试成绩以及与前一学年招生背景相似但见习方法不同的学生见习后测试成绩对比,评价教学效果。结果 98.7%的学生认为这种见习方式有助于提高读图能力,85.3%的学生认为学习心电图的兴趣得到了提高,78.7%的学生认为自己基本掌握了心电图分析方法,61.3%的学生认为自己的读图能力有了显著提高。见习前后两次测试成绩比较,见习后明显好于见习前(P<0.05)。对比2017级和2016级长学制学生的见习后测试成绩。两者招生模式相同,心电图见习后测试的考题完全一致(考题严格保密不泄露),结果发现两组成绩的差异没有统计学意义。结论教学组探索了一套学时压缩的高效实用的心电图见习教学方法。对这套方法加以调整,便可应用于非疫情时期的线下见习,当未来需要进行线上见习时,教学组的方法同样适用。

AIM To explore an efficient electrocardiogram(ECG) teaching method for probationary medical undergraduates. METHODS With shortened class hours, we meticulously designed the “twostage, three-step, and eight-link” ECG teaching method for probationary medical undergraduates and its efficacy was evaluated through post-class questionnaire and test. We also compared the post-probation test scores between students with similar enrollment backgrounds but were taught through different probation methods. RESULTS We found that 98.7% of the students were satisfied with this set of method, 85.3% of them felt their interest of ECG was aroused and 61.3% of them believed that they had made big progress in ECG interpretation. Their post-probation test scores were significantly higher than those before probation(P<0.05). CONCLUSION Our “two-stage, three-step, and eight-link” probation teaching method with shortened class hours is successful and efficient. With appropriate modification,our method can be applied under different circumstances, such as traditional full-class-hour off-line probation teaching and online probation teaching in future.
