控制变量法是指适时恰当地控制对我们所要研究的物理量相关的或有影响的因素、条件,在众多的会引起物理量发生变化的因素中,只让要研究的因素发生变化、发生改变,观察物理量会如何随着这个因素的变化而变化,而让其他的暂时不研究的因素保持不变。在初中物理教学中控制变量法是最常用的研究方法,下面就控制变量法和自己在初中物理教学中的体会进行阐述:一、控制变量法在初中物理教学中的地位 Control variable method refers to timely and appropriate control of the physical quantity we want to study the relevant or influential factors, conditions, in a large number of factors that will cause physical changes, only to study the factors change, change, observe How physical quantities change as the factor changes, leaving other factors not to be studied for the time being. In the junior high school physics teaching control variable method is the most commonly used research methods, the following on the control variable method and their experience in junior high school physics teaching elaborated: First, the control variable method in junior high school physics teaching position
