Application of virtual reality technology combined with case-based learning in forward surgical team skill teaching for undergraduates

目的探索虚拟现实技术联合案例教学在本科生前沿外科手术队(forward surgical team,FST)基本技能教学中的应用效果。方法选取2020年1月至2021年1月在海军军医大学第二附属医院进行临床实习的42名本科学员作为研究对象,随机分为试验组和对照组,分别采用虚拟现实技术联合案例教学及传统教学进行FST基本技能教学。通过问卷调查和考核评估的方式评价教学效果。采用SPSS 23.0进行t检验、卡方检验或Fisher确切概率法。结果问卷调查显示,两组学员对教学的整体满意度、学习中理解和实践情况、学习后记忆效果评分相近;而在理论知识提升、技能操作提升、分析解决实际问题能力的提高以及学习兴趣和积极性、学习注意力、学习互动等方面,试验组的评分优于对照组[(4.33±0.26)vs.(4.17±0.21),(4.32±0.22)vs.(4.12±0.27),(4.04±0.37)vs.(3.69±0.38),(4.34±0.28)vs.(3.92±0.43),(4.21±0.35)vs.(3.81±0.34),(4.18±0.29)vs.(4.01±0.21),P<0.05]。考核结果显示,试验组总评得分明显高于对照组[(85.96±5.35)vs.(77.03±7.29),P<0.001],其中理论基础得分及技能操作得分均明显更优[(28.25±4.74)vs.(25.01±5.37),(57.47±4.96)vs.(51.99±8.03),P<0.05]。结论虚拟现实技术联合案例教学对于本科生FST基本技能教学有独特优势,可进一步开展相关研究及应用。

Objective To investigate the application of virtual reality technology combined with case-based learning in forward surgical team(FST)basic skill teaching for undergraduates.Methods A total of 42 undergraduates who received clinical practice in The Second Affiliated Hospital of Navy Medical University from January 2020 to January 2021 were selected as research subjects,and they were randomly divided into experimental group(virtual reality technology combined with case-based learning for FST basic skill teaching)and control group(traditional teaching methods for FST basic skill teaching).A questionnaire survey and assessments were performed to evaluate the effectiveness of teaching,and SPSS 23.0 was used to perform the t-test,the chi-square test,or the Fisher's exact test.Results The questionnaire survey showed that there were no significant differences between the two groups in the degree of overall satisfaction with teaching,comprehension and practice in learning,and post-learning memory,and compared with the control group,the experimental group had significantly higher scores of improvement in theoretical knowledge(4.33±0.26 vs.4.17±0.21,P<0.05),improvement in skill operation(4.32±0.22 vs.4.12±0.27,P<0.05),improvement in the ability to analyze and solve practical problems(4.04±0.37 vs.3.69±0.38,P<0.05),learning interest and enthusiasm(4.34±0.28 vs.3.92±0.43,P<0.05),learning attention(4.21±0.35 vs.3.81±0.34,P<0.05),and learning interaction(4.18±0.29 vs.4.01±0.21,P<0.05).The results of assessments showed that compared with the control group,the experimental group had a significantly higher total score(85.96±5.35 vs.77.03±7.29,P<0.05)and significantly better scores of theoretical knowledge(28.25±4.74 vs.25.01±5.37,P<0.05)and skill operation(57.47±4.96 vs.51.99±8.03,P<0.05).Conclusions Virtual reality technology combined with case-based learning has unique advantages in FST basic skill teaching for undergraduates,and related studies and application research can be conducted in the future.
