技工学校有一门机械专业基础课,叫工程力学,里面包含了很多抽象的力学概念和理论,学生一般较难理解。学好这门课需要有较好的数学和物理知识,而且还要有一定的空问想象力,而技校学生刚刚初中毕业,所学的基础知识很有限,一般基础较差,抽象思维的能力有较大的局限性,因而他们要学好这门课就更难。笔者在技校教学多年,在这方面作过一定程度的探索,也自认为找到了一两个窍门。举几个轻易即可做到的例子看看。隐藏在汽车方向盘里面的科学道理
Mechanics School has a mechanical basic course, called Engineering Mechanics, which contains a lot of abstract concepts and theories of mechanics, students generally more difficult to understand. Learning this course requires good mathematical and physical knowledge, but also has some spatial imagination, and technical school students just graduated from junior high school, learned a very limited basic knowledge, the general basis of poor, abercrombie and fitch, the ability of abstract thinking Big limitation, so it’s harder for them to learn this class. The author has been teaching in technical schools for many years, and has made some explorations in this field. I also think I found one or two tips. Take a few easy to see examples of things to do.
