一、对第六章教材系统性的体会“氧化物、硷、酸、盐”一章教材的重要性:通过这章的教学,给学生树立无机物质分类的概念,认识各类化合物的通性和它们之间的联系,对高中进一步学习各类元素起着很大的作用。但是,这些知识如何教给学生则是值得研究的问题。所以这章教材编写系统如何,对教学起着很大的作用。新课本第六章教材在编写上的特点是每一类化合物都分两次提出。分两次提出,绝不是单纯的重复。原因有二:第一,因为提到某一类化合物必要牵涉到另一类化合物,如提到酸的性质,就要牵涉到硷和盐;提到酸性氧化物的性质,也必须要联系到酸和硷。所以不能一次便把某类化合物的知识全部讲完。第二,旧课本,难点比较集中,一次把酸类,硷类,盐类的知识教给学生,而学生又缺少在这方面知识的基础,因
I. Systematic Experience of Chapter Six Teaching Materials The Importance of Teaching Material Chapter of Oxides, Alkaloids, Acids and Salts: Through the teaching of this chapter, students are given the concept of classification of inorganic substances and the generality of various compounds And the link between them, for high school to further study various elements plays a big role. However, how this knowledge is taught to students is a question worth studying. Therefore, this chapter teaching system how to write, plays a big role in teaching. The sixth chapter of the new textbook teaching materials in the preparation of the characteristics of each type of compound are presented twice. Made in two places, by no means simply repeat. There are two reasons for this: First, since it is necessary to refer to another class of compounds for mention of certain classes of compounds, mentioning the nature of the acid involves alkaline and salt; mentioning the nature of acidic oxides must also be linked Acid and alkali. So I can not put all the knowledge of a class of compounds all finished. Second, the old textbooks are more difficult to deal with. They once taught the students knowledge of acids, bases and salts, and the students lacked the basis for knowledge in this respect
