树立清晰的数学概念不仅是确切而牢固地掌握数学知识的基础,也是进行运算的先决条件。我在数学概念教学中,注意了以下几点: 一、正确地阐明概念 概念是人们思维的出发点。只有使学生真正理解了数学概念,他们才能够自觉地掌握数学规律,正确地进行判断和推理。所谓讲清楚概念,就是要明确概念的内涵和外延,也就是确定概念的含义和运用范围。比如,我们在讲正方体的特征时,可以这样说:正方体有六个相等的面;但不能说成“正方体是由六个相等的面组成的”,这是因为“面”是依附于“体”而不能单独存在的。另外,对数学概
Establishing a clear mathematical concept is not only the basis for a firm and firm grasp of mathematical knowledge, but also a precondition for computing. In my teaching of mathematical concepts, I noticed the following points: First, to correctly explain the concept of concept is the starting point of people's thinking. Only by enabling students to truly understand the concept of mathematics can they master the laws of mathematics and correctly make judgments and reasoning. The so-called clear concept, it is necessary to clarify the connotation and extension of the concept, that is, to determine the meaning of the concept and scope of use. For example, when we talk about the characteristics of a cube, we can say that the cube has six equal faces, but we can not say that the cube consists of six equal faces. This is because the “face” is attached to the body "And can not stand alone. In addition, math summary
