二次函数是初中代数教材中最重要、最丰富的内容之一,是初中数学教学的重点和难点。二次函数在初中函数的教学中有重要地位,是同学们感觉较难的一部分内容,同时它又是进一步学习高中数学的基础。因此学好这部分内容显得尤为重要。那怎样才能学好这部分的内容呢?下面谈谈我个人的一些看法。一正确理解二次函数的概念对概念的理解是学习的基础。如果概念不清,就会思维混乱,计算、推理发生错误。不少学生只是形式地掌握和记 The quadratic function is one of the most important and abundant contents of junior high school algebra textbooks, which is the key and difficult point of junior high school mathematics teaching. The quadratic function plays an important role in the teaching of junior high school functions and is a part of what students feel more difficult. At the same time, it is the basis for further study of high school mathematics. So learning this part of the content is particularly important. How to learn the content of this part? Here to talk about some of my personal views. A correct understanding of the concept of quadratic function of the concept of understanding is the basis for learning. If the concept is not clear, it will be confused thinking, calculation, reasoning error. Many students just master and remember
