数学是什么?站在不同的角度会有不同的回答。有人说:“数学是研究数量、结构、变化以及空间模型等概念的科学”;也有人说:“数学是透过抽象化和逻辑推理的使用,来计数、计算、度量物体形状及其运动规律的学问”……但当综合各种解释时,我们会发现这些解释会有一个共通性:那就是——数学是理性的。可以说,“理性”是数学的核心,是数学的实质。为此,我们的数学教学就应该追寻数学理性 What is math? Stand in different angles will have different answers. Some people say: “Mathematics is a science that studies concepts such as quantity, structure, change, and spatial models.” Others say: “Mathematics uses the abstraction and logical reasoning to count, calculate, measure the shape of objects, and The law of motion ”“ But when we combine the various explanations, we find one commonality in these explanations: that is - that mathematics is rational. It can be said that ”reason " is the core of mathematics, is the essence of mathematics. For this reason, our math teaching should follow math rationality
