空间想象力的培养和提高是制图教学中的主要任务之一,也是学生学习专业课的基础。在《机械制图中》点、线、面的投影是培养空间思维的关键内容。而且,这部分内容也是学习几何体以及后续章节的基础,因此,必须加强点、线、面的投影教学。在10年的《机械制图》教学工作中,我发现,对于这方面的内容,学生学透彻了,将在以后的学习中,起到事半功倍的效果,而且能大大提高学生学习制图的积极性。下面浅谈几点本人在教学实践中对于
The cultivation and improvement of spatial imagination is one of the main tasks in cartographic teaching and also the basis of students’ specialized courses. In the “mechanical drawing” point, line, surface projection is the key to cultivate space thinking. Moreover, this part is also the basis for learning the geometry and subsequent chapters. Therefore, it is necessary to strengthen the projection teaching of points, lines and surfaces. During the 10 years of “mechanical drawing” teaching work, I found that for this content, students learn thoroughly, will play a multiplier effect in the future study, but also can greatly enhance students’ motivation to learn drawing. Here to talk about a few points in my teaching practice
