元素符号是整个化学用语教学的基础,是初中学生开始学习化学遇到的第一个难点,也是第一个分化点,我们要注意教好。元素符号与我国制定的元素名称(汉字)之间,缺少便于学生联想、记忆的因素,每种元素符号对学生都是一个孤立的“外文符号”,在引不起他们兴趣的情况下,识记元素符号是一件苦差事,教师若不事先采取一些有效措施,及至第一章第六节,二十七个元素符号一股脑儿出现在学生面前,要求他们一下子熟记,将是非常困难的。如果元素符号没有过关,对以后学习分子式、化 The symbol of the element is the basis of the teaching of the entire chemical language. It is the first difficulty encountered by junior high school students when they begin to learn chemistry. It is also the first point of differentiation. We must pay attention to teaching. Between the element symbol and the element name (Chinese character) formulated by our country, there is a lack of factors that make it easy for the student to associate and remember. Each element symbol is an isolated “foreign symbol” for the student. If they can’t draw their interest, Remembering the element symbol is a chore.
