摘要：随着新标准课程教育改革的不断推进，广大数学教师集思广益，创设大量的教学方法，积极转变教学模式，使得我国教育行业的整体教学环境呈现较大程度的改观。诚然，当新的教学变革出现彰显效果之际，往往也会带来许许多多意想不到的影响和结果。广大教师应认真、细心的对待当前教学改革中带来的一系列变化。且根据这些变化的影响及结果及时调整对我们的教学工作。例如在初中数学教学课堂来说，数形结合思想的广泛引用即已经对初中数学教学了强烈的反响，本文将简述数形结合思想，分析其主要教育价值和作用。 关键词：初中数学；数形结合；教育价值；具体应用

Admittedly， when the new teaching reform appears to be effective， it often brings many unexpected impacts and results. The majority of

teachers should be careful and careful in dealing with a series of changes brought about by the current teaching reform. And adjust our teaching work in time according to the effects and results of these changes. For example， in the junior middle school mathematics teaching class， the extensive reference of the combination of number and shape has been strongly repercussions for the

mathematics teaching in junior middle school. This paper will briefly describe the combination of numbers and forms， and analyze their main educational value and function. Then put forward the specific application of the combination of number and shape in junior middle school mathematics topic.

Key words： junior middle school mathematics； combination of numbers and shapes； educational value； concrete application； 前言：

数学知识主要研究“数”与“形”两大主要方面。数形结合思想是在新课改后被广大教师重点提及。在初中数学课堂中运用数形结合思想有利于帮助初中生建立科学的数学思维，促进知识的消化来理解，提高学生的解题能力，提高初中生的学习兴趣。笔者将在初中数学教学中的具体应用进行细致的分析与研究。 1 简述数形结合
