如何引入数学概念,是教学中值得认真探讨的一个问题。本文根据个人的体会,谈谈小学数学教学中引入数学概念的几种基本途径,以供教学时参考。一、利用数学原型引入数学概念如前所述,所谓数学概念,就是客观事物的数量关系或空间形式的本质属性在人们头脑中的反映。其数量关系或空间形式具有特定本质属性的一类事物,就是引入有关数学概念的数学原型。在小学数学教学中,利用小学生熟悉的数学原型,在增强小学生的感
How to introduce the concept of mathematics is a problem that should be seriously discussed in teaching. Based on personal experience, this article talked about several basic ways to introduce the concept of mathematics in elementary mathematics teaching for reference when teaching. I. INTRODUCING MATHEMATICAL CONCEPTS USING MATHEMATICS Prototypes As mentioned above, the so-called mathematical concept is the reflection of the quantitative relationship between objective things or the essential attributes of spatial forms in people's minds. A class of things whose quantitative relations or spatial forms have particular essential attributes is the introduction of mathematical prototypes of mathematical concepts. In primary school mathematics teaching, the use of primary school mathematics familiar prototype, in enhancing the sense of primary school students
