利用三维绘图软件,直观教学首先,工程制图是一门需要空间想象能力较强的课程,需要学生掌握好空间几何、解析几何等几门数学课程,而我们中职学生数学的基础十分的差。这一状况,我们没办法去改变,也没办法去回避,我们做的只能是想办法叫他们能够接触一些比较直观的实物或者图像,来弥补他们空间想象能力不足的劣势。我们可以利用一些模型,做成可拆装的教具;或者找一些实际生产中的零件,并缩小比例,做成模型,上课一边 The use of three-dimensional graphics software, visual teaching First of all, engineering drawing is a need to space imagination of the strong curriculum, students need to master the geometry of geometry, analytic geometry and several other math courses, and our secondary vocational mathematics is very poor. In this situation, we can not change and there is no way to avoid it. All we can do is to find ways to make them have access to some more in-kind objects or images to make up for their inadequate spatial imagination. We can use some models to make disassembly aids, or find some actual production of parts, and reduce the proportion, make a model, class side
