利用APOS理论透视无理数的概念教学

Using APOS Theory to Perspective Concept Teaching of Irrational Numbers

概念是学好数学的基础,而对概念的理解则是教学中的重点。以人教版七年级下册无理数的概念为例,运用APOS理论的四个阶段对其教学过程进行分析,基于APOS理论归纳出概念教学的一般模式,其分为四个阶段:活动、程序、对象、图式。

Concept is the basis of learning mathematics,and understanding of concepts is the focus of teaching.The author who teaches the concept version of grade seven irrational number as an example,using the four stages of APOS theory to analyze the teaching process,APOS theory summed up the general model based on the concept of teaching,which is divided into four stages:activity,process,object and schema.
