翻转微课在小儿传染病学教学中的设计应用

目的 探讨翻转微课模式在小儿传染病学教学中的应用效果。方法 以重庆医科大学2019级五年制儿科系199名学生为研究对象，分为14组。每组选择一个靶向课程重难点的微课主题，通过翻转课堂，制作原创微课视频，作品上传至超星平台供师生评价。结课后采用问卷调查教学效果，并对2019级与2018级五年制儿科学本科生的期末考试成绩及实习阶段出科考试成绩进行比较。采用SPSS 22.0统计学软件进行t检验、Wilcoxon秩和检验、卡方检验或Fisher精确检验。结果 学生共完成14个翻转微课作品。98.47%（193/196）的学生认为这一模式有助于掌握教学重难点；93.88%（184/196）的人认为相比既往的读书报告、文献综述等，翻转微课作品原创性和作业质量更好；94.90%（186/196）的学生更愿意接受翻转微课模式。2019级学生期末考试成绩、实习阶段出科考核理论成绩及操作成绩分别为（79.32±7.53）分、（88.68±4.87）分、（84.93±7.56）分，均高于2018级的（76.06±12.01）分、（87.15±4.09）分、（82.08±9.10）分，差异有统计学意义（P<0.001）。结论 翻转微课能有效解决小儿传染病学教学中的重难点问题，激发了学生自主学习的兴趣，有助于提高学习成绩，值得推广。

Design and application of flipped classroom combined with micro-lectures in the teaching of pediatric infectious diseases

Objective To investigate the application effect of flipped classroom combined with micro-lectures in the teaching of pediatric infectious diseases.Methods A total of 199 five-year students in the class of 2019 from Department of Pediatrics of Chongqing Medical University were divided into 14 groups. Each group selected a micro-lecture theme targeting the key and difficult points of the course and produced an original micro-lecture video through flipped classroom, which was then uploaded to Chaoxing platform for evaluation by teachers and students. At the end of the course, a questionnaire survey was performed to investigate the teaching effect, and final examination score and department examination score during internship were compared between the students in the class of 2019 and those in the class of 2018. SPSS 22.0 was used to perform the t-test, the Wilcoxon rank-sum test, the chi-square test, and the Fisher''s exact test.Results A total of 14 flipped micro-lecture works were completed by the students. The questionnaire survey showed that 98.47% (193/196) of the students thought that this model was helpful to master the key and difficult points; 93.88% (184/196) of the students thought that the flipped micro-lecture works had better originality and quality than reading reports and literature reviews in the past; 94.90% (186/196) of the students were more willing to accept the mode of flipped classroom combined with micro-lectures. Compared with the students in the class of 2018, the students in the class of 2019 had significantly higher final examination score (79.32±7.53 vs. 76.06±12.01, P<0.001), theoretical score of department examination (88.68±4.87 vs. 87.15±4.09, P<0.001), and operation score of department examination (84.93±7.56 vs. 82.08±9.10, P<0.001).Conclusion Flipped classroom combined with micro-lectures can effectively solve the key and difficult points in the teaching of pediatric infectious diseases, and it can also stimulate the interest in independent learning and help to improve learning performance among students. Therefore, it holds promise for clinical application.
