数形结合在初中数学解题中的应用

Application of Combination of Number and Shape in Mathematics Problem Solving in Junior Middle School

数形结合是教师在教授数学这门抽象性极强的学科时经常使用的教学思想,它以数量为基础,以图形为辅助,将抽象的数学问题转化为具体的实际问题。文章结合作者的初中数学教学经验,提出了三种应用数形结合思想解题策略,以期为更多教师的应用提供方向,从而提高教师的教学水平,提升学生的解题效率。

The combination of numbers and figures is a teaching idea often used by teachers in teaching mathematics,which is an abstract subject.It is based on quantity and assisted by graphics,and converts abstract mathematical problems into concrete practical problems.Based on the author’s experience in junior high school mathematics teaching,this paper puts forward three strategies of solving problems by using the idea of combining numbers and figures,in order to provide direction for more teachers’application,so as to improve teachers’teaching level and students’problem solving efficiency.
