在初中课程中,物理也是相对重要的一门学科,然而电学是初中物理课程中非常重要的学习内容,还为之后学习电学知识奠定了基础。但是对于初中学生来讲初次接触物理课程的电学知识比较困难,因为电学内容相对较复杂,致使初中学生学习电学知识的效果比较低。为了初中学生可以容易接受,提高学生的学习兴趣和学习效率,在初中物理电学课程学习中运用了控制变量法。所以此文主要分析物理电学中控制变量法的重要性。
Physics is also a relatively important subject in the junior secondary curriculum. However, electricity is a very important part of the junior high school physics curriculum. It also lays the foundation for later learning of electrical knowledge. However, it is difficult for the junior high school students to contact with the electrical knowledge of the physics curriculum for the first time, because the electrical content is relatively complicated, resulting in the junior high school students learning the effect of electrical knowledge is relatively low. For junior high school students can easily accept, improve students’ interest in learning and learning efficiency, the control variable method is used in junior high school physics and electrical courses. Therefore, this paper mainly analyzes the importance of the control variable method in physical electricity.
