加强函数概念的教学是提高中学数学教学貭量的一个重要問題,因而如何理解函数教学在中学数学教学中的意义,它的教学要求是什么,在教学中应該注意什么問題就成为每一个数学教师所关心的問題。本文拟就对这些問題談談个人的一些极其粗浅的看法,請同志們批評指正。一、函数教学在中学数学教学中的重要性函数是中学代数課程中的重要概念之一,这一概念之所以重要,不仅在于它是中学代数教学內容的中心,而且它是从初等数学过渡到高等数学的基本枢紐。众所周知,数的概念、恆等变形、方程、函数构成了中学代数的基本內容,其中对于方程的教学,基本上不外是两个方面:一方面是列方程,另一方面是解方程。布列方程就是求出反映某些量与量之間的函数表示式,并使之等于某个已知的数值;或者使某两个函数关系式相等。而解方程是找出这些量中未知量的数值,
Strengthening the teaching of functional concepts is an important issue in improving mathematics teaching in middle schools. Therefore, how to understand the significance of functional teaching in middle school mathematics teaching, what its teaching requirements are, and what problems should be paid attention to in teaching is every mathematics. Problems that teachers care about. This article intends to talk about some of the individual’s extremely superficial views on these issues and ask the comrades to criticize and correct them. First, the importance of function teaching in middle school mathematics teaching is one of the important concepts in the middle school algebra course. This concept is important not only because it is the center of algebra teaching content in middle school, but also because it is a transition from elementary mathematics to The basic hub of higher mathematics. As we all know, the concept of numbers, identity transformations, equations, and functions constitute the basic content of algebra in middle schools. There are basically two aspects to the teaching of equations: on the one hand, equations on the other hand, and on the other hand, solutions to equations. A Boulle equation is to find a functional expression between some quantity and quantity, and make it equal to a certain known value; or to equalize two functional formulas. The solution equation is to find the unknown value of these quantities,
