数学概念是反映现实世界的数量关系和空间形式的本质属性和内在联系的思维形式,是对一类数学对象本质特征的概括。可以说“数学是从概念出发的”。因此,理解、掌握数学概念是学好数学的前提和保证。在课堂教学中,运用逻辑方法,分析、归纳概念间的关系,使各个概念间有较强的联系,体现出各个概念之间的结构性,对学生正确掌握概念的内涵和外延,深刻理解并牢固地掌握、灵活地运用概念有重要作用。
The concept of mathematics is a kind of thinking that reflects the relationship between the quantity and the nature of the real world and the intrinsic relationship between the spatial forms and the internal relations. It is a generalization of the essential characteristics of a class of mathematical objects. It can be said that “mathematics is from the concept of ”. Therefore, to understand and grasp the concept of mathematics is a prerequisite and guarantee for learning mathematics. In the classroom teaching, the use of logical methods to analyze and summarize the relationship between concepts, so that there is a strong relationship between the concepts, reflecting the structure of the various concepts, the students correctly grasp the concept of connotation and denotation, a deep understanding and Firmly grasp, flexible use of concepts has an important role.
