沉浸式虚拟现实技术在静脉注射法实验教学中的应用

The application of Immersive Virtual Reality technology in experimental teaching of intravenous injection

目的:评价沉浸式虚拟现实技术在静脉注射法实验教学中的应用效果。方法:采用随机对照研究的方法,将某高校2017级学生分为实验组(n=62)和对照组(n=63),在"真人对练+模型辅助+虚拟训练"三位一体的混合式教学模式下,比较沉浸式(实验组)和非沉浸式(对照组)两种不同虚拟现实技术在静脉注射法实验教学中的实施效果。结果:干预后两组学生的理论考核成绩明显高于干预前,实验组的操作考核成绩优于对照组(P<0.05);学生总体上对沉浸式教学技术比较满意,实验组评判性思维与临床推理维度及临床学习维度满意度得分明显高于对照组(P<0.05)。结论:沉浸式虚拟现实技术提高了学生对实验操作内容的掌握程度,学生对虚拟体验的满意度较高;沉浸式虚拟现实技术在护理实验教学领域有良好的应用前景。

Objective:To explore the application effect of Immersive Virtual Reality technology in experiment teaching of intravenous injection.Methods:A randomized controlled trial was conducted and 125 students from the class of 2017 from a university were divided randomly into the experimental group(n=62)and the control group(n=63).Immersive Virtual Reality(the experimental group)and Non-immersive Virtual Reality(the control group)were compared under the trinity teaching mode of"real person training+model assistance+virtual training".Results:The post-test scores of the two groups were significantly higher than the pre-test scores after intervention,the performance of the experimental group is better than that of the control group(P<0.05).Students were generally satisfied with immersive teaching technology.The dimension scores of critical thinking and clinical reasoning and clinical learning in the experimental group was significantly higher than those in the control group(P<0.05).Conclusion:Immersive Virtual Reality technology improves students’mastery of teaching content,and students’satisfaction with virtual experience is high.Immersive Virtual Reality technology has a good application prospect in the field of nursing experiment teaching.
