数学抽象是对事物的空间形式与数量关系的抽象,数学研究所涉及的基本概念并不一定都是直接从现实具体的存在中抽象出来的,可以借助符号与类比得到更高层次的抽象,从而达到高度的形式化,而小学生的思维特点是以具体形象思维为主,逐步向抽象思维过渡,这就是数学让学生感觉枯燥与难学的重要原因。因而数学教学有一个重要的教学原则:抽象性与具体性相结合的原则。涉及到具体教学内容时,如何处理抽象与直观的关系,提高抽象水平,提升数学
Mathematical abstraction is the abstraction of the relationship between the spatial form and the quantity of things. The basic concepts involved in mathematical research are not always abstracted directly from the concrete existence of reality, but can be abstracted to a higher level by means of symbols and analogies Achieve a high degree of formalization, while the thinking characteristics of primary school students are mainly based on specific image thinking, and gradually transition to abstract thinking, which is why mathematics makes students feel boring and difficult to learn important reasons. Therefore, mathematics teaching has an important teaching principle: the principle of combining abstractness and concreteness. When it comes to specific teaching content, how to deal with the relationship between the abstract and the intuitive, to improve the level of abstraction, improve mathematics
