在解题过程中,往往比较充分、全面地反映学生解题的能力.数学能力是指运用数学知识和方法去分析、解决问题的能力.要提高数学能力主要依靠刘.数学知识和方法的理解和应用. 函数在中学数学的教学占有十分重要的位置,数形结合又是初等数学最重要的思想方法之一.教学大纲强调“通过数形结合的思想,进行对立统一的教育.”因此利用函数图象解题在
In the problem-solving process, students’ ability to solve problems is often fully and fully reflected. Mathematical ability refers to the ability to use mathematical knowledge and methods to analyze and solve problems. To improve the ability of mathematics depends mainly on Liu. Understanding of mathematical knowledge and methods. And applications. Functions occupy a very important position in the teaching of middle school mathematics, and the combination of number and shape is one of the most important ideas and methods of elementary mathematics. The syllabus emphasizes “through the idea of combining numbers and shapes, and conduct education on the unity of opposites.” Function image problem solving
