APOS理论是美国数学教育家杜宾斯基(Dubinsky)等人提出的一种建构主义学说,它的一个基本假设是:数学知识是个体在解决所感知到的数学问题的过程中获得的.在这个过程中,个体依序建构了心理活动(Action)、程序(Process)和对象(Object),最终组织成用以理解问题情境的图式结构(Scheme).APOS理论克服了传统的“概念同化教学模式”中忽 APOS theory is a constructivist theory proposed by Dubinsky et al., A mathematical educator in the United States. Its basic hypothesis is that mathematical knowledge is obtained by individuals during the process of solving the perceived mathematical problems. In this process, an individual constructs the Action, Process and Object in sequence, and organizes them into schemas to understand the context of the problem.APOS theory overcomes the traditional concept of “ Assimilation teaching mode ”in the sudden
