数学是数量的科学,是研究现实世果空间形式和数量关系的,它是根据人类的需要而产生的。为了能够在纯粹的数学状态中去研究这些形式和关系,就必须抛弃现实世界的物质内容,用抽象的数学形式把它们表现出来。因此,中学数学教学也必然要经常遇到实际问题的数学抽象。下面,就这一问题谈谈我们肤浅的看法。 Mathematics is a quantity of science, is to study the relationship between spatial form and quantity of the real world, it is based on human needs. To be able to study these forms and relations in a purely mathematical state, one must discard the material contents of the real world and present them in abstract mathematical forms. Therefore, high school mathematics teaching must also often encounter the practical problems of mathematical abstraction. Now let’s talk about our superficial view on this issue.
