PowerPoint软件在机械制图教学中的巧用

The skillful use of Power Point software in the teaching of "Mechanical Drawing"

帮助机电专业学生掌握几何体的平面图形与三维空间形体对应关系的构建,通过教师小组采用行动研究法和案例研究法,利用Power Point软件对"机械制图"学科教学进行教学改革,探索、改进"机械制图"学科教学方法,增强学生对机械制图绘图原理"长对正、宽相等、高平齐"的理解,逐步建立空间想象力,让学生轻松听得懂、看得懂和学得会,提高机电专业学生对"机械制图"学科知识的理解、掌握和实际运用。

To help students who major in Machinery and Electrical Engineer establish the professionals framework for the corresponding relations between plan views and three-dimensional figures of geometries, the authors study and improve the teaching approach in the course of ＂Mechanical Drawing＂ by using the action research method and case study method and introducing Microsoft Office Power Point into the course. The paper shows the way can help students further understand the principle of mechanical drawing, i.e. the same length, the same width and the same height, and foster the ability of space imagination. Let students be able to make sense of the knowledge of ＂Mechanical Drawing＂ more easily, and improve their ability in mastering and applying the knowledge of ＂Mechanical Drawing＂.
