数学是由概念与命题等等内容组成的知识体系,概念是数学知识体系中的“细胞”。教师只有教会学生正确地理解数学中的每个概念,才能正确地掌握与运用由这些概念所形成和发展起来的数学知识。中学数学教学大纲已指明:“正确理解数学概念是掌握数学基础知识的前提”。
Mathematics is a knowledge system composed of concepts and propositions and so on. The concept is the “cell” in the system of mathematical knowledge. Only by teaching students to correctly understand each concept in mathematics can teachers correctly master and use the mathematical knowledge formed and developed by these concepts. The secondary school mathematics syllabus has stated: “The correct understanding of mathematical concepts is the prerequisite for mastering the basic knowledge of mathematics.”
