在物理教学中常讲到矢量和标量,而物理教材中只是给出了这两个量的定义,对这两个量的区分和来龙去脉没有明确的、严格的、科学的规定。其中有些矢量和标量学生能够分清,而有些学生则分不清,并且存在一些似是而非的问题。为此,笔者认为在物理教学中,最为理想的方法是:第一,弄清矢量和标量概念及似是而非的问题;第二;确定矢量和标量的几个基本量;第三,找出矢量和标量之外的矢量和标量形成方式和规律性。
In physics teaching, we often talk about vector and scalar, but physics textbook only gives the definitions of these two quantities. There is no clear, strict and scientific stipulation on the distinction and the ins and outs of these two quantities. Some of these vector and scalar students can distinguish, while others can not tell, and there are some specious issues. For this reason, I think the most ideal method in physics teaching is: First, to find out the concept of vector and scalar and paradoxical problem; secondly, to determine several basic quantities of vector and scalar; third, to find out vector and Scalar vectors and scalar forms and regularities.
