摘要
函数知识是中学数学的核心内容,学生关于函数概念的认知发展过程可分成以下3个阶段:(1)作为“算式”的函数;(2)作为“变化过程”的函数;(3)作为“对应关系”的函数.学生是否真正理解函数概念,关键在于其表象的形成和发展水平.
With the relevant investigation, analysis and research was carried out from students in grade three in junior school to students in grade one and two in senior school. The conclusion was reached that students?cognitive process of the function concept had three stages: (1) function as formula of operation? (2) function as 損rocess of variation? and (3) function as 搑elation of correspondence?
