建构主义理论是认知主义的进一步发展,是对传统学习理论的继承与抛弃。教师所教的数学知识必须通过学生主体感知、消化、改造,建立适合他们自己的数学结构,才能被理解、掌握,并且经过反思和与环境的交流,进一步改善学生的数学结构。概念学习是数学学习的核心。函数是中学数学的基本概念,也是一个重要概念。 Constructivism theory is the further development of cognitivism, inheriting and abandoning the traditional learning theory. The mathematics knowledge taught by teachers must be perceived, digested, transformed by students, and the mathematical structure suitable for them should be understood and mastered. And the mathematical structure of students should be further improved through reflection and communication with the environment. Concept learning is the core of mathematics learning. Function is the basic concept of high school mathematics, but also an important concept.
