基于PBL的“翻转课堂”结合3D动画教程和CBL教学法在运动医学见习教学中的运用效果研究

Research on the Impact of PBL-based"Flipped Classroom"on Teaching Effect by Combining 3D Anatomy and Surgical Animation Tutorials and CBL Teaching Method in Sports Medicine Internship Teaching

目的评估基于问题教学法(Problem-based Learning,PBL)的“翻转课堂”结合基于案例教学法(Casebased learning,CBL)和3D解剖、关节镜下模拟手术视频在运动医学见习教学中的应用效果。方法选择2020年6月—2022年12月在日照市人民医院运动医学科见习的60名学生为研究对象,采用抽签法随机分为观察组和对照组,每组30名。观察组采用PBL的“翻转课堂”结合CBL教学法和3D解剖模拟手术动画视频资料进行教学,对照组采用传统教学方法进行授课讲解。对比两组学生对教学模式的评分、见习考核结果及对教学模式的满意度。结果观察组教学模式评分、见习考核结果、教学满意度高于对照组,差异有统计学意义(P均<0.05)。结论采用基于PBL的“翻转课堂”教学方法结合CBL和3D模拟手术视频可显著提高运动医学科见习医师的临床知识水平和整体满意度。

Objective To evaluate the application effect of the"flipped classroom"based on problem based learning(PBL)combined with case-based learning(CBL)and 3D anatomy,and arthroscopic simulated surgeryvideos in sports medicine internship teaching.Methods 60 students who were intern in the Sports Medicine Department of Rizhao People's Hospital from June 2020 to December 2022 were selected as the research subjects.The students were randomly divided into observation group and control group by lottery method,with 30 cases in each group.The observation group used PBL's"flipped classroom"combined with CBL teaching method and 3D anatomy simulation surgery animation video materials for teaching,while the control group used traditional teaching methods for teaching and explanation.The trainees'ratings of the teaching model,trainee assessment results,and satisfaction with the teaching model between two groups of students were compared.Results The teaching model score,internship assessment results and teaching satisfaction of the observation group were higher than those of the control group,and the differences were statistically significant(all P<0.05).Conclusion Using the"flipped classroom"teaching method based on PBL combined with CBL and 3D simulated surgical videos can significantly improve the clinical knowledge level and overall satisfaction of trainee doctors in the sports medicine department.
