化学基本概念是整个中学化学知识的基础,准确理解概念、原理对学好化学是十分重要的。初中化学基本概念多,且比较抽象,是初中学生难以掌握的内容之一;这些概念和原理是否准确理解、是否熟练掌握对学好初中化学关系很大,是形成正确实验技能、计算技能的依据,是分析和解决化学问题的基础。而初中学生的阅读和理解能力比较差,且对概念、原理学习不重视,认为掌握概念就是死记硬背。学法不当,效果不好,这部分内容是考试易 The basic concept of chemistry is the basis of chemistry knowledge of the whole middle school. It is very important to understand the concept and principle in order to learn chemistry well. Junior high school chemistry more than the basic concepts, and more abstract, is difficult for junior high school students to grasp one of the contents of these concepts and principles are accurate understanding of whether the mastery of good chemistry junior high school chemistry is the basis for the formation of the correct experimental skills, computational skills, It is the basis for analyzing and solving chemical problems. The junior high school students’ ability of reading and comprehension is relatively poor, and they neglect the concepts and principles of learning. They think that mastering concepts is rote learning. Improper learning method, the effect is not good, this part of the content is easy to test
