【摘要】 针对汽车拖拉机构造学实践课程传统教学中存在的弊端和实验装置及实验场地的限制问题，提出将三维虚拟现实技术用于汽车拖拉机构造学的实践教学中。探讨了虚实结合的实践教学改革模式，根据不同的实践性质和内容，确定了虚实结合实践教学的形式；对实验课的考核方法进行了创新，通过多角度、多途径的多点联合考核，建立了一套科学的、立体的、全面的评价系统。实践证明，基于拖拉机拆装教学软件的虚实结合的实践教学模式弥补了传统实习的缺点，在实际教学中充分调动学生的学习积极性，收到了较好的效果。更多还原

【Abstract】 According to the present drawback of the practice course teaching of Automobile Tractor Tectonics and the limitation of the experimental equipment and the experimental site, the 3D virtual reality technology was used in automobile tractor tectonics in the practice teaching. Virtuality and reality combination of practice teaching reform was discussed, according to the different nature and content of practice, the form of practice teaching combining virtuality and reality was determined. Evaluation mode of experiment examination way was reformed, and teaching effect was scientific evaluated. The multi-point collaborative assessment of multiangle and multi-way was designed to build a scientific three-dimensional comprehensive evaluation system. It has been found that virtuality and reality combination of practice teaching reform based on the tractor disassembling educational software make up for the shortcomings of traditional practice. In the actual teaching, the students’ learning enthusiasm was fully mobilized, and good results have been received.更多还原
