摘要
《机械原理》教学过程中发现学生对一些抽象概念的理解比较困难,不能很好的利用基本原理解决问题,为了使学生能够熟练掌握这类概念,并能灵活应用,本文以描述机构运动情况的速度瞬心这个概念为例,通过利用语言描述,图形表达和公式推演等方法相结合的方式来对概念进行讲述,使学生不仅从多个角度理解和掌握概念的内涵,并且能够明白概念间的相互联系。通过此种教学方式教学效果有了较好的改善,学生普遍反映对概念的理解更容易。
There are some difficulties for the students to learn the concepts in the Theory of Machines,and have no idea how to use them.In order to make the students master these kind of concepts and use them very freely,the comprehensive application of image-text and formula which were more complex in mechanism to describe the concepts was used.The students can master the concepts very well and apply them very freely.Through this kind of teaching method,the teaching effect had better improvement,and the students generally reflected the understanding of the concept more easily.
