以问题为导向结合显微手术视频系统的教学模式在诊治儿童眼睑缺损教学中的应用

Practice of teaching pediatric eyelid defect diseases using video display system and problem-based learning

目的评估以问题为导向学习(PBL)结合显微手术视频系统在诊治儿童眼睑缺损教学中的应用效果。设计回顾性比较性教学研究。研究对象北京儿童医院眼整形专业组内轮转的各类住院医师25人。方法接受传统教学模式的住院医师12人,接受改革教学模式(即PBL结合显微手术视频系统观摩手术操作的教学模式)的住院医师13人,比较组间教学效果的差异。主要指标疾病诊断准确率、重要手术步骤的正确识别率和基本眼整形显微技术的掌握率。结果改革教学组的疾病诊断准确率为100%(13/13)、重要手术步骤的正确识别率为92.3%(12/13)、基本眼整形显微技术的掌握率为92.3%(12/13),分别高于传统教学组的58.3%(8/12)(P=0.039)、50.0%(6/12)(P=0.030)和41.7%(5/12)(P=0.011)。结论手术显微镜视频系统联合PBL模式可改善眼睑缺损修复手术的教学效果。

Objective To evaluate the teaching efficacy of video display system combined with problem-based learning(PBL)on pediatric eyelid defect diseases.Design Retrospective comparative teaching study.Participants 25 residents were analyzed retrospectively.Methods 12 residents accepted the traditional teaching mode and 13 residents accepted the reformed teaching mode,which was a new approach using video display system and PBL.The differences of teaching effects between the groups were compared.Main Outcome Measures The accuracy of disease diagnosis,the correct identification of important surgical steps and the mastery of basic ocular plastic microscopy.Results In the traditional teaching group,the accuracy of disease diagnosis was 58.3%(8/12),the correct recognition rate of important surgical steps was 50.0%(6/12),and the mastery rate of basic ophthalmoplasty microscopy was 41.7%(5/12).The outcome measures of the reform teaching group were 100%(13/13),92.3%(12/13)and 92.3%(12/13),respectively.There were significant differences between the two groups(P=0.039,0.030,0.011).Conclusion Teaching effect of video display system of surgical microscope combining PBL teaching model has been significantly improved.
