公式的应用、基本概念的理解和记忆是高中数学中的重点,然而在解题过程中,过于注重公式和定义可能会使学生的思路有所限制。如果学生能运用数形结合的方法解题,就能绕过题目中的障碍,使解题变得容易。教师应在日常的数学教学中为高中生渗透数形结合的解题方法,扩宽他们的思路,引导他们更灵活的思考问题,提高数学解题能力。本文就高中数学中数形结合方法进行探讨。一、利用数形结合,完成初中到高中的过渡相比于初中的知识,高中的数学知识更加抽象,高中生需要学会
The application of formulas and the understanding and memory of basic concepts are the key points in high school mathematics. However, paying too much attention to formulas and definitions in solving problems may limit the students’ thinking. If students are able to solve the problem using a combination of numbers and forms, they can bypass the obstacles in the subject and make the problem easier. Teachers should peruse high school students in the daily math teaching to solve the problem of combining numbers and forms, broaden their thinking, guide them to think more flexibly and improve the ability of solving problems in math. This article discusses the combination of number and form in high school mathematics. First, the use of combination of figures to complete the transition from middle school to high school Compared to junior high school knowledge, high school mathematics knowledge is more abstract, high school students need to learn
