数形结合是初中数学中重要的思维方法之一。在初中总是将数学分为代数、几何和三角函数,这些无不包含数和形两大基础概念。初中数学总是将表示数量关系的数和具体直观的图形融为一体,将抽象思维与形象思维有机统一起来,在认知数学的过程中,经常采取把数量问题转化为直观的图形性质、位置关系的讨论,或者将图形蕴含的关系转化为相应的数量计算。因此,在初中数学教学中驱动学生的数形结合的思维尤为重要,本文就是基于此点而引发的感慨。
Combination of numbers is one of the important thinking methods in junior high school mathematics. In junior high school mathematics is always divided into algebra, geometry and trigonometry functions, which all contain two basic concepts of number and shape. In the process of cognitive mathematics, mathematics of junior middle school always takes the number of relations between quantity and the concrete and intuitive graphics as a whole, organically unifies the abstract thinking and the thinking of the image, and often takes the problem of quantity into an intuitive graphical nature in the process of cognitive mathematics. Discussion of the relationship, or the relationship between the graphics into a corresponding number of calculations. Therefore, it is very important to think in combination of the number-form driving students in junior high school mathematics teaching. This article is based on this feeling.
