从教高中化学多年,在教授新知的同时,发现一些化学知识,在高中阶段未讲,初中阶段也未讲,但在平时的教学中经常提到,在高考中也经常出现。因此笔者结合高中化学教材的实际,找出了初高中化学之间需要过渡与链接的内容,献给广大师生。一、常见的分类法物质的分类方法有多种,目前高中化学教材中主要有两种分类方法:树状分类法和交叉分类法。
From teaching chemistry to chemistry for many years, while teaching the new knowledge, we found some chemistry knowledge, did not say in high school, junior high school did not say, but often mentioned in teaching, often appear in college entrance examination. Therefore, the author combined with the actual teaching of high school chemistry, identified the need to transition and link between the contents of the initial high school chemistry, dedicated to the majority of teachers and students. First, the common classification method There are many kinds of material classification methods, the current high school chemistry textbooks there are two main classification methods: tree classification and cross-classification.
