学过数学的学生往往最弄不清楚的就是到底什么是函数,有的学生一提到函数就头疼,学生对于函数确实是有一些畏难情绪的.我认为学生感觉函数难,正是因为没有搞清函数最本质的东西,也就是函数的概念,于是我在这一节的教授中花了一些心思,这里把我的一些具体做法与思考写出来与同行交流.首先创设问题情境:问题一、你能谈谈对函数的认识吗?问题二、函数的本质是什么?让学生回顾初中学习过的函数概念,把握住函数的内涵.教师根据学生所举例子的具体情况,引导学生列举分别用解析 Students who have learned math are often most confused about what functions are, and some students have a headache when it comes to functions. Students do have some hard feelings about functions, and I think it is hard for students to feel the function because it is not done Function of the most essential things, that is, the concept of the function, so I spent some time in the professor’s mind here to write some of my specific practices and thinking to communicate with their peers. First create a problem situation: the first problem, Can you talk about the understanding of the function? Question two, what is the nature of the function? Let students review the concept of function learned in junior high school, to grasp the meaning of the function of the teacher according to the specific circumstances of the students cited examples, guide students to enumerate separately Analysis
