数学概念是反映现实世界空间形式和数量关系本质属性的思维形式。数学知识中最普遍的形式是概念,所以概念教学是数学教学的核心。数学实践表明,学生在解决数学问题时出错或产生困难,原因往往在于概念的理解上产生了障碍,因此必须十分重视概念教学。 The concept of mathematics is a form of thinking that reflects the essential attributes of the relationship between the spatial form and the quantity of the real world. The most common form of mathematical knowledge is concept, so concept teaching is the core of mathematics teaching. Mathematical practice shows that when students solve mistakes or cause problems in mathematics, they often encounter obstacles in the understanding of concepts. Therefore, they must attach great importance to the teaching of concepts.
