函数是近现代数学的基础,是中学数学中最重要,也是最复杂的概念.学生对函数本质的理解可划分为4个水平:前结构水平、单结构水平、多结构水平和关系结构水平.高一学生函数对应关系的理解整体水平偏低的原因有:函数本身的复杂性、发展性和教学的问题.数学教学中要更新教学观念,注重理解的数学教学,要掌握有利于促进理解的教学方法.
Function is the foundation of modern mathematics and the most important and complicated concept in middle school mathematics. Students’ understanding of the nature of function can be divided into four levels: pre-structure level, single-structure level, multi-structure level and relational structure level. The reasons for the low overall level of understanding of the corresponding relationship of high school students include: the complexity of the function itself, development and teaching problems. To update the teaching concepts in mathematics teaching, pay attention to the understanding of mathematics teaching, to grasp is conducive to promoting understanding teaching method.
