中学数学教学大纲明确指出,要用辩证唯物主义观点阐述教学内容,揭示数学中的辩证关系。而作为研究客观世界中的数量关系和空间形式的数学,也必然反映客观世界中的辩证规律。本文结合教学实践,谈一下如何利用对立、统一、变化发展的观点培养中学生的数学辩证思维能力。1已知与未知的相互转化已知与未知,一方面界线分明,相互对立;另一方面又相互联系、可以转化。从已知到未知这种由因导果的综合法可以使诸多问题得到顺利解决。从未知出发对求已知与未知的关系,这种
High school mathematics syllabus clearly pointed out that we should use dialectical materialist point of view of teaching content, to reveal the dialectical relationship in mathematics. And as a mathematical study of the quantitative relations and spatial forms in the objective world, it is inevitable to reflect the dialectical laws in the objective world. This article, combined with the teaching practice, talks about how to use the viewpoints of antagonism, unity and change and development to develop the dialectical thinking ability of middle school students. 1 known and unknown mutual transformation between known and unknown, on the one hand clear boundaries, mutually antagonistic; the other hand, they are interconnected and can be transformed. From known to unknown, this combination of causes and consequences can lead to many problems being solved smoothly. From unknown to seek known and unknown relationship, this
