初中阶段所学的化学用语主要是元素符号、离子符号、化学式、化合价以及化学方程式等,这些不但是学生学好化学的重要工具,也是众多化学用语的基础,所以初中化学用语的教学就显得十分重要。但是由于这部分知识记忆量大,抽象性强,又比较枯燥,而且学生从未接触过,但又是教学中的重点和难点,往往会使学生产生畏难情绪,认为记化学用语比记英语单词还难,从而形成初中化学的第一个分化点。
The chemical terms used in junior middle school are mainly elementary symbols, ionic symbols, chemical formulas, valences and chemical equations, which are not only important tools for students to learn chemistry, but also the basis of many chemical terms, so the teaching of junior middle school chemical terms is very important . However, because of this part of the large amount of knowledge and memory, abstract, and more boring, and the students have never been exposed, but it is the teaching of the key and difficult points, often make students fear of emotion, Difficult to form the first point of differentiation of junior high school chemistry.
