## 一元二次函数学习中遇到的问题及解决方法

The Problems and Solutions in the Study of Quadratic function
Abstract
Quadratic function is important and difficult in the junior high school mathematics. It is different that between the mathematics which students learned before and the quadratic function. Students need to master quadratic function of the nature of learning through junior high school, and to identify skillful drawing an image by a quadratic function and image reading hidden information, problem-solving experience with the image of a new way of thinking. Most students cannot have a good grasp of the nature of a quadratic function. According to the problems appeared in the practical teaching of quadratic function teaching, the students conducted a questionnaire survey and interviews of teachers, analyzed the problems for students to accept, causes of problems and solutions
Key words: quadratic function  teaching management  survey  problems countermeasures

2 二次函数的重点和难点

而二次函数是初中函数的重点和难点，它与学生之前所接触的数学学习都有所不同，学生要通过初中的学习掌握二次函数的性质、熟练辨认并绘制二次函数的图像并能通过图像读出隐含信息、体会用图像解题的新的思想方法.可以说，二次函数是初中数学的集大成者，初中数学的很大一部分学科都是为二次函数打下基础.学生要改变固有思维方式，打破常规才能学好二次函数，并且在不断的演练中体会数学思想，灵活的应用二次函数的特征[2].在这一角度说，这也是初中数学的一大难点. 一元二次函数学习中遇到的问题及解决方法:http://www.lwfree.cn/shuxue/20191027/41562.html
