机械制图少学时教学研究与实践

High-efficiency Teaching in Mechanical Drawing

目前各高等职业院校根据自己的办学特色和办学优势,在多数理工科专业中都要开设机械制图与计算机绘图课程,但是除机械类或近机械类专业外,课时都比较少,大约是30学时即2个学分,如果采用传统的教学理念和教学方法,老师教得累学生学得累,学生本身对非专业课程就不重视,整个学习过程处于被动的学习状态,尽管教师很努力但教学效果也不尽如人意。笔者经过近十年机械制图与计算机绘图少学时教学研究与实践,并组织同行老师的共同努力,把不同的教学方法运用到不同的教学内容中去,可以得到很好的教学效果,学生通过不同的教学方法来进行学习,在较短的时间内获得更多的理论知识和实践性知识,又能在计算机上掌握较多的绘图技能,达到了事半功倍的教学效果。

Currently characteristics and advantages have formed in most higher vocational colleges. Mechanical drawing and computer graphics courses are offered in most science and engi- neering specialties. But very few class hours are spent on these courses, only 30 class hours, 2 credits. Should traditional teach- ing ideas and methods are employed, it would be time-consum- ing. The students would lose interest and be passive in learning. Through many years＇ exploration in teaching, we have found that different teaching methods lead to highly efficient class effect and that the students learn more theoretical and practical knowledge and master more skills at drawing on the computer in a given time.
