在初中数学学习过程中,学生对函数的学习存在着较大困难,一方面是由于学生的年龄特点和心理特征,造成理解和接受函数知识的困难;另一方面是由于数学知识进一步的抽象和拓展,造成掌握和运用函数知识的困难。函数概念和性质的内容不像方程和不等式那样简单、具体、明了。学生感到困难的是:不知道函数是什么,函数的图像是怎么来的,为什么要研究函数的图像,函数的图像与函数的性质存在什么关系,函数
In the process of junior high school mathematics learning, students have great difficulties in learning the function. On the one hand, due to the age and psychological characteristics of students, difficulties in understanding and accepting functional knowledge are caused. On the other hand, due to the further abstraction of mathematical knowledge Expansion, resulting in the mastery and use of functional knowledge of the difficulties. The concept and nature of the function are not as simple, concrete, and explicit as equations and inequalities. Students feel difficult: do not know what the function is, the image of the function is how to come, why study the function of the image, the image of the function and the nature of the function What is the relationship between the function
