数学思想是指人们对数学理论和内容的本质认识,数学方法是数学思想的具体化形式,数学思想方法是数学学习的核心.初中数学中的许多问题,蕴涵着丰富的数学思想方法.分式运算中的化简与求值题是考查学生的基础知识及创新能力的重要题型.对其中某些题目,若能根据其结构特点,合理运用数学思想方法,寻找恰当的解题途径,可以简化运算,起到事半功倍的效果.
Mathematical thinking refers to people’s understanding of the nature of mathematical theory and content, mathematical method is the concrete form of mathematical thought, mathematical thinking method is the core of mathematics learning.Many problems in junior high school mathematics contain a wealth of mathematical thinking method. The simplification and evaluation of the operation is an important question to examine the students’ basic knowledge and innovation ability.Of some of the questions, according to its structural characteristics, the rational use of mathematical thinking and methods to find the appropriate way to solve problems, you can Simplify computing, play a multiplier effect.
