“控制变量法”是初中物理探究实验的基本方法,该设计思想贯穿初中物理教材的始终。这样,会让学生在探究涉及多个变量的物理问题时,把“控制变量”作为实验设计的首要选项,让“控制变量”的意识在学生大脑中根深蒂固。人教版初中物理教材中,第一次明确提出“控制变量”的是八年级下册《浮力》中“探究浮力的大 ”Control Variable Method “ is the basic method of junior high school physics exploration experiment, this design philosophy runs through the junior middle school physics teaching material from beginning to end. This will allow students to think of ”Control Variables “ as the primary option for experimental design while exploring the physical issues involved in multiple variables, leaving the notion of ”Control Variables “ ingrained in the student’s brain. People’s Education Edition of junior high school physics textbooks, the first explicitly put forward ”control variables“ is the eighth grade ”buoyancy“ in the ”buoyancy of the large
