初中物理电学中控制变量法的应用探讨

Application of control variable method in electrical engineering of junior middle school

电学是初中物理十分重要的内容,同时作为基础教育阶段,该时期的电学知识将直接影响到学生今后电学知识学习的效果与能力。就当前教育结果来看,初中生大多存在感性认知点偏低的问题。由于电学本身内容较为复杂,所以大多数初中生的物理学习都会遇到很大的阻碍,电学知识学习结果不尽人意。为提高电学教学有效性,改善初中生电学知识学习效率低下的问题。本文将以控制变量法为途径,重点分析与探讨初中物理电学教学中的控制变量法应用,希望可以帮助更多的教师与学生。

the content of the electricity is junior high school physics is very important,at the same time as the basic education stage,the period of the electrical knowledge will directly affect the students in the future electronic knowledge learning and ability is the effect of the current education,junior middle school students mostly perceptual cognition point on the low side of problems due to the electrical itself content is relatively complex,so most of the junior middle school students physical learning will meet a lot of obstacles,electrical knowledge learning result unsatisfactory in order to improve electrical teaching effectiveness,improve the low efficiency of electrical knowledge in junior high school students This paper will focus on the analysis and discussion of the application of the control variable method in the teaching of physics and electricity in junior high school through the method of control variable,in the hope of helping more teachers and students.
