摘　　要：目的探索虚拟现实技术结合动作捕捉系统在刷牙宣教教学中的教学效果。方法选取上海交通大学医学院附属第九人民医院口腔规培生36名,随机分为A、B两组,A组(19人)采用传统教学法;B组(17人)采用虚拟现实技术结合动作捕捉系统教学。A组教师采用ppt讲课和模型进行示范教学,学生练习,教学前和教学后进行技能考核。B组学生采用基于MR和动作捕捉系统的刷牙虚拟仿真实验教学系统进行学习,教学前和教学后进行技能考核。最后,通过问卷调查进行教学效果评价。计量资料采用SPSS 22.0进行t检验分析。结果A组的教学前实践考核平均成绩为(70.8±18.63)分,B组教学前实践考核平均成绩为(63.6±15.98)分,两者差异无统计学意义(P>0.05)。A组的教学后实践考核平均成绩为(92.7±5.36)分,B组教学后实践考核平均成绩为(91.2±6.55)分,两组教学后成绩均比教学前显著提高(P<0.01),两者之间差异无统计学意义(P>0.05)。调查问卷结果显示,与A组相比,B组更能提高学习兴趣、学习积极性和主动性。结论虚拟现实技术结合动作捕捉系统在刷牙宣教教学中的应用对于学生技能掌握效果与传统教学方法相同,但更有利于学生提高自主学习的能力,值得在口腔宣教教学中推广。Objective The study aimed to explore the teaching effect of virtual reality technology combined with motion capture system in brushing education.Methods Thirty six students were selected from the Ninth People's Hospital Affiliated to the Medical College of Shanghai Jiaotong University,and were randomly divided into two groups:group A(19 students)used the traditional teaching method;Group B(17 persons)adopted virtual reality technology and motion capture system for teaching.Group A teachers use ppt lectures and models for demonstration teaching,students practice,and conduct skills assessment before and after teaching.Group B students used the virtual simulation experiment teaching system of brushing based on MR and motion capture system to learn,and the skills were assessed before and after teaching.Finally,the teaching effect is evaluated by questionnaire.SPSS 22.0 was used for t-test and chi square test.Results The average score of pre-teaching practice examination in group A was(70.8±18.63),and the average score of pre-teaching practice examination in group B was(63.6±15.98).There was no statistical difference between the two groups(P>0.05).The average score of post-teaching practice assessment in Group A was(92.7±5.36),and the average score of post-teaching practice assessment in Group B was(91.2±6.55).The post-teaching performance in both groups was significantly higher than that before teaching(P<0.01),and there was no statistical difference between the two groups(P>0.05).The results of the questionnaire show that compared with Group A,Group B can improve learning interest,enthusiasm and initiative.Conclusion The application of virtual reality technology combined with motion capture system in brushing education has the same effect on students’skill mastery as traditional teaching methods,but it is more beneficial for students to improve their self-learning ability,and it is worth popularizing in oral education.
