机械制图是工程专业学生必须的基础课程,是当前职高学生普遍反应较难的一门课程,教学的难点和重点是学生立体思维的建立和空间形体与平面图形相互转化。由于职校生没有接触立体几何知识,在学习机械制图的道路上,遇到了很多困难。为此,如何突破这些难点,培养学生的空间思维和创造能力,是每个《机械制图》课教育工作者所必须认真研究的问题。
Mechanical drawing is a necessary basic course for students majoring in engineering. It is a course which is generally difficult for vocational college students to respond to. The difficulty and emphasis of teaching are the establishment of students’ three-dimensional thinking and the mutual transformation of the space form and the plane figure. As vocational school students do not have access to solid geometry knowledge, they encountered many difficulties in learning mechanical drawing. Therefore, how to break through these difficulties and cultivate students’ space thinking and creativity is a problem that every educator in Mechanical Drawing must seriously study.
