数学是初中教育重要组成部分,也是教学的重点和难点。其中数形结合思想指将抽象概念逻辑结合直观数学图形,进而让学生学会抽象思维和形象思维结合能力并对其转化。数形结合解题思想和其他解题方法相比有着易接受和形象性、直观性特点,教师在教学中引导学生应用数形结合解题思想能锻炼学生分析问题和解决问题能力,从而更好地掌握和理解数学知识。本文则从函数问题、面积问题、应用题等问题中分析数学数形结合思想应用,望给予初中数学教师提供教学参考。
Mathematics is an important part of junior high school education, but also the teaching of the key and difficult. Among them, the idea of combining numbers and shapes refers to the combination of abstract conceptual logic and intuitive mathematical graphics, which in turn enables students to learn and transform the combination of abstract thinking and visual thinking. Compared with other problem-solving methods, digital form has the characteristics of easy acceptance and vividness and intuitiveness. Teachers can guide students in teaching to use digital form combined with problem-solving ideas to train students to analyze and solve problems so as to be better Grasp and understand maths knowledge. This article analyzes the application of the combination of mathematical figures and forms from the aspects of function problems, area problems and application problems, and hopes to provide junior high school mathematics teachers with teaching reference.
