《数学课程标准》中指出:“学生在数学学习的内容有利于学生主动地进行观察、实验、猜测、验证、推理与交流等数学活动。”“建构主义理论认为:数学并非是一个被动接受的过程,而是一个以已有知识经验为基础的主动建构的过程,也是再创造的过程。”因此,我们的初中数学课堂教学应创设一种符合学生认知规律的、轻松和谐的学习氛围,应该鼓励学生自主探究和合作交流,并不断地自我反思,最终能灵活解决数学问题。新课程标准基本出发点是促进学生全面、持续、和谐地发展,它不仅要考虑数学自身的特点,更要 The Mathematics Curriculum Standards states: “The students’ learning content in mathematics is conducive to students actively performing observations, experiments, guessing, verification, reasoning, and communication. Mathematical activity in the ”“ constructivist theory: Mathematics is not a The process of passive acceptance is a process of active construction based on existing knowledge and experience, and it is also a process of re-creation.” Therefore, our junior middle school mathematics classroom teaching should create a relaxed harmony that conforms to the students’ cognitive laws. The learning atmosphere should encourage students to explore independently and cooperate and communicate, and constantly self-reflection, and eventually be able to solve mathematical problems flexibly. The basic starting point of the new curriculum standards is to promote students to develop in a comprehensive, sustained, and harmonious manner. It must not only consider the characteristics of mathematics itself, but also
