The Problems of Electricity Learning in Middle School Science and the Teaching Strategies

初中物理知识逻辑性较强,尤其是电学部门,其复杂程度令很多学生头痛不已。在学习电学这一知识点时,应着重培养学生的观察、实验、思维和运用的能力,很多学生虽然把电学基本原理、欧姆定律等定义和有关的公式、规律背得滚瓜烂熟,但解决实际应用题时却无从下手。因为该章节涉及的难点多、公式多、规律多、概念多,且容量较大,令很多学生短期之内难以掌握。然而,只要掌握一定的要领、技巧或方法,哪怕再难的内容,我们亦能悉心掌握;平时勤加练习,善于总结,那么提高成绩也不是难事,怎样让学生感觉电学不难,怎样让学生愿意学呢?下面我们就探讨一下如何做好电学知识的教学。

Middle school physics knowledge is highly logical, especially the electricity part which is extremely complicated, making students upset. In the learning of electricity, we should lay emphasis on the cultivation of students＇ abilities of observation,experiment, thinking and application, because many students have no way of solving practical problems although they have thoroughly memorized the basic principles of electricity, Ohm＇s Law, and related formulas and rules. The reason of the above phenomenon is that this chapter involves a lot of difficulty points,formulas, rules and definitions which make it difficult for students to grasp in a short time. However, if students grasp certain essentials, skills and methods, they can also easily grasp the above contents no matter how difficult they are. If students can practice a lot and summarize a lot in routine learning, they will easily improve their academic performance. This paper mainly explores how to implement electricity teaching, in order to make it easy for students to learn and make students willing to learn.
