初中数学中蕴含的数学思想方法很多,最基本的数学思想方法有符号与换元的思想、化归的思想、数形结合的思想、分类讨论的思想、方程的思想等,突出这些基本思想方法,就相当于抓住了中学数学知识的精髓.因此,在初中数学教学中至少应该向学生渗透以下几种主要的数学思想方法.一、符号表述与换元的思想方法符号表述是数学语言的重要特色,它能使数学思维过程更加概括、简明.一句复杂的数学语言在用数学符号来表述时,让
There are many mathematical thinking methods in junior middle school mathematics. The most basic mathematical thinking methods are the symbolic and redemptional thoughts, the naturalized thought, the combination of several forms, the thought of classified discussion, the equation of thought, etc., highlighting these basic ideas and methods , It is equivalent to grasp the essence of high school mathematics knowledge.Therefore, at least junior high school mathematics teaching should at least permeate the students the following kinds of mathematical ideas and methods.First, the way of thinking of symbolic representation and exchange yuan Symbolic expression is mathematical language Important features, it can make the mathematical thinking process more general, concise. A complex mathematical language in the use of mathematical symbols to express, let
