化学用语教学主要是元素符号—化合价—化学式—化学方程式这一主线的教学。它是初中化学的一个难点,也是学生对化学学习的一个关键点。上述化学用语在初三化学体系中的地位是十分重要的,一般说来前两个单元检测成绩都比较理想,但是从三单元元素符号开始到四单元的化合价、化学式及五单元的方程式就有部分学生陆续的掉队了。问题就是学生对化学用语学习掌握的不好,逐渐失去兴趣和信心。所以在化学用语的教学中一定要夯实基础,想方设法让学生掌握的扎实一些,帮助学生渡过难关。

Chemical language teaching is the main element of the symbol - valence - chemical formula - chemical equation of the main line of teaching. It is a difficult chemical in junior high school and a key point for students to learn chemistry. The chemical terms in the junior chemical system is very important in the position, in general, the first two units test results are ideal, but from the beginning of the three-element symbol to the four-unit valence, chemical and five-unit equations have Some students one after another left behind. The problem is that students have poor mastery of chemical terms and gradually lose interest and confidence. Therefore, in the teaching of chemical terms must lay a solid foundation, find ways to make students have a solid grasp of some, to help students weather the storm.
