虚拟现实技术在眼科临床教学中的应用

Application of virtual reality technology in clinical teaching of ophthalmology

目的观察虚拟现实技术在眼科临床教学中的应用价值。设计前瞻性随机对照研究。研究对象2019年3月至10月在西南医科大学附属医院眼科实习的本科学生48名。方法将48名学生随机分为两组,实验组24名,对照组24名。实验组实施虚拟现实技术教学,对照组实施传统方式教学。教学主要内容为眼的组织解剖和生理生化,由6名带习教师随机分配进行教学,每次教学时间均为120分钟。课后及课后1个月分别对学生进行一次试卷测试,课后对学生和教师进行一次问卷调查。主要指标试卷测试和问卷评分。结果实验组的课后试卷测试平均成绩(90.63±6.65)分高于对照组(86.04±8.07)分(t=-2.147,P=0.037);实验组的课后1个月试卷测试平均成绩(85.21±7.14)分高于对照组(78.54±9.50)分(t=-2.748,P=0.009)。实验组学生的问卷调查结果(8.53±0.49)分高于对照组(7.49±0.58)分(t=-6.701,P=0.000);实验组教师的问卷调查结果(9.03±0.21)分高于对照组(8.17±0.47)分(t=-2.907,P=0.044)。结论相较传统教学方式,虚拟现实技术应用于眼科临床教学具有潜在的优势,是一项值得推广的教学方法。(眼科,2021,30:240-243)

Objective To observe the applicational value of virtual reality technology in ophthalmology clinical teaching.Design Prospective randomized controlled study.Participants 48 undergraduate students of ophthalmology internship in Affiliated Hospital of Southwest Medical University from March to October in 2019.Methods 48 students were divided into two group,the experimental group(24 students)and the control group(24 students)randomly.The experimental group were taught with virtual reality technology and the control group were given traditional teaching.They were taught with the anatomy,physiology and biochemistry of the eyes.Six teachers were randomly assigned,and each teaching time was 120 minutes.The students were tested after the course on the day and 1 month after internship.The students and teachers were evaluated by questionnaire.Main Outcome Measures Paper tests and questionnaire score.Results The average paper test score of experimental group(90.63±6.65)was higher than that of control group(86.04±8.07)(t=-2.147,P=0.037);the average paper test score for one month after class of experimental group(85.21±7.14)was higher than that of control group(78.54±9.50)(t=-2.748,P=0.009).The questionnaire score of students in experimental group(8.53±0.49)was higher than that of control group(7.49±0.58)(t=-6.701,P=0.000);the questionnaire score of teachers in experimental group(9.03±0.21)was higher than that of control group(8.17±0.47)(t=-2.907,P=0.044).Conclusion Compared with traditional teaching,the virtual reality technology in clinical ophthalmology teaching has potential advantages,and it is a new teaching method worth popularizing.(Ophthalmol CHN,2021,30:240-243)
