1引言数学概念是人类对现实世界空间形式和数量关系的概括反映,是建立数学法则、公式、定理的基础,也是运算、推理、判断和证明的基石,更是数学思维、交流的工具~([1])。由此可见,数学概念是数学的基础,从概念入手,逐渐呈现更加深入的数学知识是数学教材编写的基本思路。阅读教材是教师备课的基本环节,数学教材中概念的编写可能会直接影响一堂数学概念课,因此,数学教材中数学概念的编写极其重要。函数是高中数学知识体系中的核心内容,是贯穿高中
1 INTRODUCTION The concept of mathematics is a general reflection of mankind’s relation to the form and quantity of the space in the world. It is the foundation for the establishment of mathematical laws, formulas and theorems, as well as the cornerstone of computing, reasoning, judging and proving. It is also a tool for mathematical thinking and communication. [1]). Thus, the concept of mathematics is the basis of mathematics, starting from the concept, and gradually presents a more in-depth knowledge of mathematics is the basic idea of mathematics textbooks. Reading materials is the basic part of teacher preparation. The compilation of concepts in mathematics textbooks may directly affect a mathematical concept class. Therefore, the compilation of mathematical concepts in math textbooks is extremely important. Function is the core of high school mathematics knowledge system, is run through high school
