【摘要】：“VR”元年始于2016,Virtual Reality,VR(虚拟现实技术)的发展和教育应用越来越受到教育技术领域的重视。虚拟现实技术的桌面式三维虚拟学习环境,能给学生带来更好的学习体验,改变传统教学模式成为了可能。因此如何将三维虚拟仿真技术应用到汽车维修专业教学中,把虚拟仿真技术融入到技工职业教育教学中,让学生在校园内就能够体验到汽车维修企业的工作流程和标准以及最新现代汽车技术。学生只需要在学校的机房进行虚拟学习,操作软件。之前的实训设备短缺,更新缓慢,资金不足等实际问题,也能巧妙解决、学生弄懂了知识,掌握了技能,这对汽车维修实训有很大的帮助,同时也让我们看到虚拟仿真技术在汽车维修教学中运用的巨大潜力。本文首先做了汽车维修专业的教学需求分析,查阅了不仅国内包括国外的大量文献,总结分析了国内外虚拟实验室教学应用状况的基础上,阐述了建构主义学习理论和情境认知理论等相关学习理论对三维虚拟仿真教学系统搭建的理论指导意义,将现代教育技术学理论和三维虚拟仿真技术结合起来,开发出具有交互功能的三维虚拟仿真教学系统,并将其应用于实际的教学课堂中。其次根据汽车维修专业课程标准确立了设计目标,功能需求为基础搭建虚拟仿真教学系统,同时以汽车底盘的齿轮齿条式转向系统教学为例,运用3Dmax2010、VC++6.0开发平台和OpenGL技术实现人机交互,最后通过测试完成“汽车维修虚拟仿真教学系统”的搭建,该系统是针对技工教育,职业培训和中高职院校等汽车维修教学所开发的技能教学培训系统,让全体学员只需在机房就能够进行汽车零部件的拆卸和组装操作练习,而且能反复练习,不损耗实物。虚拟教学系统搭建完成后,应用阶段采用对比的方法,选取一个班(1班)学生和另一班(2班)学生做对照试验。依据教学理论设计了“虚实”混合教学模式并对教学试验应用效果进行了测试评价。包括自评,互评,理论考试,实际操作,4个方面进行考核评价。结果表明,虚拟仿真教学模式能够充分发挥学生的主体作用,有效了提高教学效果。最后总结了汽车维修虚拟仿真教学应用中的不足之处,以及对将来的更近一步探讨和研究进行了计划和展望。本论文对汽车维修虚拟教学系统搭建进行了技术上的尝试,教育教学理论方面的思考,在一体教学项目中,引入先虚拟教学,后实际操作,虚实结合教学模式案例探讨,为汽车维修专业教学运用虚拟仿真研究的提出了一些想法,积累了经验。
[Abstract]:The first year of "VR" began in 2016 with the development of Virtual reality Technology (VR) and its application in education. The virtual reality technology desktop virtual learning environment can bring students a better learning experience. It is possible to change the traditional teaching mode, so how to apply the 3D virtual simulation technology to the automobile maintenance teaching, and how to integrate the virtual simulation technology into the vocational education of mechanic. Students will be able to experience the working processes and standards of auto repair companies and the latest modern automotive technology on campus. Students only need virtual learning in the school's computer room to operate software. Previous training equipment is short of equipment and updating is slow. Practical problems, such as insufficient funds, can also be solved skillfully. Students understand knowledge and master skills, which is of great help to vehicle maintenance training. At the same time, let us also see the great potential of virtual simulation technology in automobile maintenance teaching. Firstly, this paper makes an analysis of the teaching requirements of automobile maintenance major, and looks up a large number of documents not only at home and abroad, but also abroad. On the basis of summarizing and analyzing the application of virtual laboratory teaching at home and abroad, this paper expounds the theoretical guiding significance of constructivism learning theory and situational cognition theory to the construction of 3D virtual simulation teaching system. Combining modern educational technology theory with 3D virtual simulation technology, a 3D virtual simulation teaching system with interactive function is developed. And it is applied to the actual teaching classroom. Secondly, according to the course standard of automobile maintenance specialty, the design goal is established, and the virtual simulation teaching system is built on the basis of functional requirements. At the same time, the teaching of the gear-rack steering system of the automobile chassis is taken as an example. Using 3Dmax2010VC6.0 development platform and OpenGL technology to realize man-machine interaction, finally through the test to complete the "vehicle maintenance virtual simulation teaching system", the system is aimed at the mechanic education, The skill teaching and training system developed by vocational training and automobile maintenance teaching in middle and higher vocational colleges enables all students to carry out disassembly and assembly of automobile parts in the machine room, and to practice repeatedly. After the virtual teaching system is completed, the application phase adopts the method of contrast, This paper selects one class (class 1) and another class (class 2) as control test. According to the teaching theory, the mixed teaching mode of "virtual reality" is designed and the application effect of teaching experiment is tested and evaluated, including self-evaluation, mutual evaluation, theoretical examination, etc. The results show that the virtual simulation teaching mode can give full play to the students' main role and effectively improve the teaching effect. Finally, the shortcomings of the application of virtual simulation teaching in automobile maintenance are summarized. As well as the future further discussion and research plan and prospect. This paper has carried on the technical attempt to the automobile maintenance virtual teaching system construction, the education teaching theory aspect ponder, in the integration teaching project, the article has carried on the technical attempt to the automobile maintenance virtual teaching system construction, the education teaching theory aspect ponder, in the integrated teaching project, This paper introduces first virtual teaching, then practical operation, discusses the case of virtual reality combined with teaching mode, and puts forward some ideas and accumulates experience for the application of virtual simulation to the teaching of automobile maintenance specialty.
