基于APOS理论的数学概念教学设计案例研究

y little attention to the early understanding of mathematics concepts and concept teaching,and the teaching focus is often on the training of students'problem-solving skills.In recent years,APOStheory is more used in mathematics concept teaching.This paper attempts to study the teachingdesign of junior high school mathematics concepts under the guidance of this theory.This paper uses the methods of interview,case study and literature study.First,it sorts out theAPOS theory and its enlightenment to the teaching of mathematical concepts,and summarizes theexisting research on its application in the teaching of mathematical concepts.Then,it puts forwardthe strategy of applying the APOS theory in the teaching of mathematical concepts in junior highschool through interview research,and gives two teaching design cases.Finally,the article issummarized,and the future development is considered and prospected.Key words APOS theory mathematical concepts teaching design目录引言.1概述…1.1研究的背景1.2研究的问题..2
