众所周知,函数概念是中学数学中的最重要概念之一,函数的思想和方法贯穿高中数学课程的始终。理解函数概念及由其反映的数学思想方法,学会用函数的观点和方法解决数学问题和现实问题,是高中阶段最重要的数学学习任务之一,因此,搞好函数概念的教学至关重要。一、注重函数概念的渗透高中函数概念:(1)设A,B是两个非空集合,如果按照某种对应法则f,对A中的任意一个元素x,在B中有一个且仅有一个元素y与x
As we all know, the concept of function is one of the most important concepts in middle school mathematics. The thought and method of function run through the high school mathematics curriculum. To understand the function concept and the mathematical thinking method reflected by it and to learn how to solve the mathematical problem and the realistic problem with the viewpoint and function of the function is one of the most important tasks of mathematics learning in high school. Therefore, it is of vital importance to improve the teaching of the function concept. First, pay attention to the concept of function infiltration High school function concepts: (1) Let A, B is a set of two non-empty, according to some corresponding law f, A for any element x, in B there and only An element y and x
