VR技术联合CBL教学在急诊住院医师规范化培训教学中的探索应用

Exploration and application of VR technology combined with CBL teaching in resident training teaching of emergency

目的 探讨虚拟现实(VR)技术联合基于案例的学习(CBL)在急诊教学中的应用效果。方法 选取2020年9月至2022年9月台州市第一人民医院40例规范化培训医师作为研究对象,采用随机数字表法将其分为实验组和传统组,每组20名。传统组采用情景模拟+讲授式教学,实验组采用VR技术联合CBL教学。比较两组理论、技能成绩及教学满意度的差异。结果 培训后,实验组学员的理论及操作考试成绩均高于传统组,差异均有统计学意义(t分别=2.58、2.38,P均<0.05)。在学习的主动性、培训模式的新颖性、提升学习效率、提升理论知识的理解、提升临床技能、加强临床思维、培训总体的满意度方面,实验组的教学满意度均高于传统组,差异均有统计学意义(t分别=3.13、3.33、2.25、2.73、2.27、2.37、2.96,P均<0.05)。实验组学员对VR课程的评分明显高于持中立态度的分值,差异有统计学意义(t=23.17,P<0.05)。结论 VR技术联合CBL教学法在急诊住院医师规范化培训教学中可以取得良好的教学效果和教学满意度,为医学教育提供了新的方法和途径。

Objective To explore the application effect of virtual reality(VR) technology combined with case-based learning(CBL) in emergency resident training teaching.Methods A total of 40 doctors from Taizhou First People's Hospital from September 2020 to September 2022 were selected as the study objects.They were divided into experimental group and traditional group by random number table,with 20 participants in each group.The traditional group adopted situational simulation and lecture-based learning,while the experimental group adopted VR technology combined with CBL.The differences of theory,skill achievement and teaching satisfaction between the two groups were compared.Results After training,the theoretical and operational test scores of the experimental group were higher than those of the traditional group,and the differences were statistically significant(t=2.58,2.38,P<0.05).In terms of learning initiative,novelty of training mode,improvement of learning efficiency,improvement of understanding of theoretical knowledge,improvement of clinical skills,strengthening of clinical thinking and overall satisfaction of training,the experimental group' s teaching satisfaction was higher than that of the traditional group(t=3.13,3.33,2.25,2.73,2.27,2.37,2.96,P<0.05).The average score of VR course evaluation of the experimental group was significantly higher than that of the traditional group,and the difference was statistically significant(t=23.17,P<0.05).Conclusion VR technology combined with CBL teaching method can achieve good teaching effect and teaching satisfaction in emergency resident training teaching,which provides a new method and way for medical education.
