摘要
函数教学既要解构,也要建构.解构是从数学的视角理解函数概念,分析函数及其相关概念构成的网络体系,找出概念的核心所在;建构是从教学的视角理解函数,将分解后的函数各相关内容重新建立联系,还原成一个整体,在寻求联系中,螺旋上升地建构函数的结构体系.
Teaching of the function needs not only deconstruction but also construction. Deconstruction means to understand the function concept from the mathematics perspective. Find out the key of the function concept by analyzing the network system formed by the function and the related concepts; Construction means to understand the function from the teaching perspective. Re-establish the contact of the function concept and each related concepts and form them into a whole part. Construct the structure system of the function spirally while seeking the relationship.
