数学按其研究的对象和方法而言,精确性是它的重要特征,因此,在数学教学中特别强调科学性是至关重要的,也就是说,在数学教学中概念必须准确无误,论证必须明确严谨。然而,数学理论又是一个具有严密逻辑性的概念体系,离开丁教材本身的系统性去谈论所谓科学性是没有什么意义的,因为科学性是寓于系统性之中的.遗憾的是,孤立地、片面地割裂教材的整个体系,去断章取义地奢谈科学性的现象,在教学活动中却屡见不鲜。 Mathematics As its object and method of study, accuracy is an important feature of it. Therefore, it is very important to emphasize science in mathematics teaching. That is to say, concepts must be accurate in mathematics teaching. Argumentation must be Clearly rigorous. However, mathematical theory is a closely logically conceptual system. It does not make sense to talk about the so-called scientific nature without systematizing the textbook itself because, unfortunately, science is embedded in the system. Regrettably, , One-sided splitting of the entire system of textbooks, go out of context to talk about the phenomenon of science, but in teaching activities are not uncommon.
