初中生函数概念发展的特点

本研究通过测验法对北京市六所中学的８０２名初一至初三的学生进行考察，研究了初中生函数要领的发展水平及其特点，结果表明，初中三个年级学生函数要领的发展，从总体上看，随着看级的增高呈上升的发展趋势，但年级结学生函数概念发展的影响不显著，制约 初中学生函数的概念发展水平的关键是，学生所受教育的质量，学生主要以接受教育的方式来获得函数概念。

The Ch racteristics of the Function Concept Development of Junior High School Students

An investigation was made of 802 students from the first grade to the third grade in 6 high schools in Beijing by means of a measuring method to study the development levels and characteristics of the function concept in junior high school students. The results showed that in general the development of the function concept tended to increase with the student s' grades, but the grade levels were not remarkably related with the development levels. The key factor which affected their development levels of function concept was the teaching quality. The students obtained their function concept through instruction.
