六种途径的“机械制图”课程教学应用与研究

Application and Research on Six Ways of "Mechanical Drawing" Teaching

近年,随着中等职业学校招生门槛降低,进校生的总体素质下滑严重。而学校第一学期就开设"机械制图"这门课程,由于学生在学习时毫无实际经验,也缺少空间立体几何知识,所以在内容的掌握上有一定的难度,因此,有不少学生产生惧学、厌学和逃学的心理。如何根据学生的实际情况和教材的特点,通过恰当的教学方法和途径,使学生在阅读和绘制机械图样时游刃有余,就显得尤为重要。本人结合自身的教学实践,将"一严"、"二勤"、"三方法"应用于"机械制图"课程教学中,这些做法在实践教学里取得了很好的效果,也赢得了同行的肯定。

With the access to secondary vocational schools becoming increasingly easy in recent years, the overall quality of secondary vocational students has severely declined, but the course ＂Mechanical Drawing＂ is opened in the first semester,when students have no experience and lack spatial solid geometry knowledge in learning, so it is difficult for them to master related knowledge, leading to many students＇ fear, weariness and even avoidance of learning. How to make students handle reading and making mechanical drawings skillfully through proper teaching methods and approaches in accordance with their practical situations and the characteristics of textbooks, seems particularly important. Combined with teaching practice, the writer introduces the application of ＂three steps＂ in the teaching of ＂Mechanical Drawing＂. These methods have achieved favorable effect and have been affirmed by colleagues.
