目的 研究虚拟现实(virtual reality,VR)联合增强现实(augmented reality,AR)融入式教学系统在临床医学专业口腔通识医学教育的应用与效果。方法 以海军军医大学2015级临床医学五年制一教班160名本科生为研究对象,分为VR+AR组和传统组,每组各80人。对两组学生的前期成绩及授课成绩进行对比分析,并于结课后进行问卷调查分析。利用Epidata 3.0进行问卷资料输入,使用SPSS 23.0软件进行t检验、卡方检验和Fisher精确检验。结果 VR+AR组与传统组在基础知识成绩上差异无统计学意义[(52.65±3.76) vs. (51.90±3.46),P=0.516],但VR+AR组在病例分析[(35.85±2.56) vs. (31.40±2.96),P<0.001]及总成绩[(88.50±4.95) vs. (83.30±4.86),P=0.002]上均高于传统组。问卷调查结果显示,VR+AR组在“教学模式”[(92.30±6.90) vs. (85.20±7.30),P<0.001]、“教学方法”[(91.70±5.90) vs. (86.00±6.70),P=0.012]和“教学提升”[(90.70±8.70) vs. (82.30±8.40),P<0.001]上评分均高于传统教学组。结论 VR联合AR融入式教学系统,可提高教学成绩与教学质量,方便用于口腔狭小空间内的教学演示、模拟操作,适用于临床医学专业口腔通识医学教育
Abstract
Objective To investigate the application and effect of the virtual reality (VR) combined with the augmented reality (AR) integrated teaching system in stomatology general medical education of clinical medicine students. Methods A total of 160 undergraduates from the five-year clinical medicine Batch 2015 of Naval Medical University were randomly divided into VR+AR group and traditional group
with 80 students in each group. A comparative analysis was made on the previous and teaching achievements of the two groups of students
and a questionnaire survey was conducted after the completion of the class. Epidata 3.0 was used to input questionnaire data
and SPSS 23.0 software was used to carry out t test
chi-square test and Fisher precision test. Results There was no statistical difference in written test scores between the VR+AR group and the traditional group [(52.65±3.76) vs. (51.90±3.46)
P = 0.516]
but the VR+AR group was significantly higher than the traditional group in case analysis scores [(35.85±2.56) vs. (31.40±2.96)
P < 0.001] and overall performance [(88.50±4.95) vs. (83.30±4.86)
P= 0.002]. The questionnaire survey results showed that the scores of teaching mode [(92.30±6.90) vs. (85.20±7.30)
P<0.001]
teaching method [(91.70±5.90) vs. (86.00±6.70)
P=0.012] and teaching improvement [(90.70± 8.70) vs. (82.30±8.40)
P<0.001] in VR + AR group were significantly higher than those in the traditional teaching group. Conclusion The VR combined with AR integrated teaching system can significantly improve teaching performance and teaching quality
and is convenient for teaching demonstrations and simulation operations in small oral spaces
and is especially suitable for oral general medical education for clinical medicine.
