数学的世界是符号化的世界,数学的语言是由一些符号与记号组成的语言,数学家波利亚说:“关于数学符号的重要性,不管怎样讲,总不是夸大的,”因此,我国数学教育界将培养学生良好的符号意识列为数学教育的目的之一,中学数学教材中含有大量的数学符号,同学们要真正学好数学,就必须正确理解、灵活运用这些数学符号隐含的信息。
The world of mathematics is a symbolic world. The language of mathematics is a language composed of symbols and signs. The mathematician Polya said: “The importance of mathematical symbols, no matter what, is not always exaggerated.” Therefore, our country The mathematics education community has cultivated students’ symbolic awareness as one of the goals of mathematics education. There are a large number of mathematical symbols in middle school mathematics textbooks. To truly learn mathematics, students must correctly understand and use the information implicit in these mathematical symbols. .
