数形结合是数学解题中常用的思想方法,无论是在平时的数学解题中,还是在高考都起到了重要的指导作用.因此,中学生掌握好数形结合思想是有重要意义的.本文试从以下几个方面加以介绍.一、如何在中学数学教学中渗透数形结合思想首先,对于一些概念的几何意义要让学生彻底理解,要达到学生能在自己的大脑中根据几何意义把图形画出来的效果,同时也能在不同的条件下准确地将图形画出.其次,在平时练习中,凡是能用数形结合思想来解
The combination of number and shape is a common way of thinking in mathematical problem solving, which plays an important guiding role both in normal mathematics problem solving and in college entrance examination.Therefore, it is of great significance for middle school students to grasp the combination of figure and form idea. First, how to penetrate the number of high school mathematics teaching combination of ideas First of all, the geometric meaning of some concepts for students to fully understand, to achieve the students in their own minds according to the geometric meaning of the graphics Draw the effect, but also under different conditions can accurately draw the graphics.Secondly, in the usual practice, all can be used to form the number of ideas to solve
