抽象函数是指没有明确给出具体的函数表达式 ,只是给出一些特殊条件的函数 ,它是中学数学函数部分的难点 .因为抽象 ,学生难以理解 ,接受困难 ;因为抽象 ,教师对教材难以处理 ,何时讲授 ,如何讲授 ,讲授哪些内容 ,采用什么方式等等 ,深感茫然无序 .本文就上述问题作一些探讨 .1 Abstract function means that there is no specific function expression given, but it is a function that gives some special conditions. It is a difficult part of the middle school math function. Because of abstraction, students find it difficult to understand and accept difficulties. Because abstraction, teachers are difficult to deal with teaching materials. , when to teach, how to teach, what to teach, what method to use, etc., deeply feel disorderly. This article makes some discussion on the above issues.
