数学概念是数学学科的基础,而函数概念又是中学数学的核心内容,它既贯穿于部分代数知识中,蕴涵着代数知识的重要思想,又是连接代数与几何知识的桥梁,它在整个中学数学教学中有着重要的地位。为了有效地进行函数概念教学,朱成万老师提出构建函数的结构体系流程,如图~([1])。 The concept of mathematics is the basis of mathematics, and the concept of function is the core of secondary mathematics. It not only runs through part of algebraic knowledge, but also contains the important thought of algebraic knowledge and bridge between algebra and geometrical knowledge. Mathematics teaching plays an important role. In order to effectively carry out the concept of function teaching, Zhu Chengwan teacher proposed the structure of the function of the system structure, as shown in Figure ~ ([1]).
