解读教材是教师备课的基本功,也是关系到教学成功与否的重要一环。数学教师如何解读教材?如何才能把抽象文本转化为生动教学?这是非常值得研究的事情。下面笔者结合几例教学案例做一下初步的探究。一、寻根溯源,解读教材数学中每一个知识点都不是孤立存在的,它们都隶属于某个知识体系,但考虑到教材编排、学生认知规律等诸多因素,教材切断了知识链条,将其分散在各个学段里。如“数的认识”中包含了自然数、整数、有理数、无理
Interpretation of teaching materials is the basic skills of teachers prepare lessons, but also relates to the success of teaching an important part. How to interpret textbooks for math teachers and how to translate abstract texts into vivid teaching? This is a very worthwhile study. Here I combine a few cases to do a preliminary study. First, root tracing, interpretation textbook Mathematics in each point of knowledge is not isolated, they are part of a knowledge system, but taking into account the teaching material arrangement, the cognitive rules of students and many other factors, the textbook cut off the knowledge chain, its Scattered in various sections. Such as “number of knowledge ” contains natural numbers, integers, rational numbers, unreasonable
