目的 评估临床医学专业学生在眼科学见习教学中采用虚拟现实(virtual reality,VR)技术辅助眼部解剖教学的效果。方法 本研究采用试验对照方法,于2020年9月至11月期间选择北京协和医学院八年制临床医学专业51名学生为研究对象,采用随机数字表法将其分为试验组和对照组。试验组25名学生采用VR解剖模型学习,对照组26名学生采用传统PVC材料教具学习。学习结束后,分别对两组学生进行眼部解剖学随堂测验,并对试验组学生进行问卷调查。结果 试验组学生眼部解剖测验分数(80.55±11.99)分,对照组学生为(71.68±15.82)分。试验组学生平均分高于对照组学生,差异具有统计学意义(t=2.25,P=0.03)。试验组96.0%(24/25)的学生认为使用VR解剖模型学习比使用传统PVC材料教具更为有趣,80.0%(20/25)的学生认为VR辅助教学模式对学习眼部解剖学很有帮助。结论 在临床医学专业学生的眼科学见习教学中采用VR技术辅助眼部解剖教学,可以提高学生对眼部解剖的理解和记忆,并且提高学生的学习兴趣。
Objective To investigate the efficacy of virtual reality (VR) based training in the teaching of ocular anatomy for undergraduates. Methods From September to November 2020, a total of 51 students from eight-year program of clinical medicine in Peking Union Medical College were enrolled. They were randomly divided into the experimental group (25 students) and control group (26 students). The experimental group was trained with VR-assistant method, while the control group was trained with traditional PVC model. The same test of ocular anatomy was used for all the students, and a questionnaire survey was implemented for the experimental group. Results The average score of experimental group was higher than control group[(80.55±11.99) vs.(71.68±15.82), t=2.25, P=0.03]. In experimental group, 96.0% (24/25) students believed that VR model was more interesting and 80.0% (20/25) students thought VR model very helpful in learning ocular anatomy. Conclusions VR model can improve students' understanding of ocular anatomy, and most students think that VR learning is more interesting.
