酸、碱、盐、氧化物的一系列知识,是明确无机物的基本概念的基础。而初中化学课进行到这一章,教材的深度与广度是比较旧课本有明显的提高。所以,我们有必要对这一章教材深入体会,做到融会贯通,深入浅出。一定要掌握住教材的精神与实质,才能达到这章的教学目的。一.深入教材的体会1.掌握原子—分子论,发挥教材的科学性与思想性——根据化学教学大纲的指示:“初中全部化学是以原子—分子论为基础的。”从一、二两章开始教物质及其性质与化学反应中,阐明原子—分子论的意义,并以原子—分子论观点解释物质性质及化学反应,基本上是可以使学生获得原子—分子
A series of knowledge of acids, bases, salts, and oxides is the basis for defining the basic concepts of inorganic matter. The junior high school chemistry class to this chapter, the depth and breadth of textbooks is significantly improved compared to the older textbooks. Therefore, it is necessary for us to have an in-depth understanding of this chapter’s teaching materials so as to make it easy to understand and explain profound theories in simple language. Must grasp the spirit and substance of teaching materials, in order to achieve the teaching purpose of this chapter. I. In-depth understanding of the teaching material 1. Grasp the atom - molecular theory, play teaching material science and thought - According to the instructions of the chemistry syllabus: “junior high school chemistry is based on atom - molecular theory.” From one two two Chapter begins to teach the substance and its nature and chemical reaction, elucidates the meaning of atom-molecule theory, and explains the matter’s nature and chemical reaction from an atom-molecular point of view, basically enabling students to obtain atom-molecule
