初中化学课本是带领学生步入化学殿堂的第一本教材。因为是启蒙教材,所以有许多知识点需要学生牢记并灵活运用。而这些内容如果死记硬背的话,耗时长,记忆容量大,记忆难度大,学生在有限的化学学习时间内完不成任务,从而影响学生学习化学的兴趣,同时又会因为学生的基础不扎实而影响化学的整体教学任务的高质量完成。 Junior high school chemistry textbook is to lead students into the first textbook of chemistry hall. Because it is enlightenment materials, so there are many points of knowledge need students to keep in mind and flexible use. If these contents are memorized, they will take a long time, have a large memory capacity, and have a difficult memory. Students will not be able to complete their tasks within a limited time of chemical study, thus affecting their interest in learning chemistry. At the same time, The overall quality of the teaching tasks that affect chemistry is accomplished.
