浅谈数学建模在探究小学“工程问题”中的应用

On the Application of Mathematical Modeling in the Exploration of "Engineering Problems" in Primary Schools

数学模型思想指用数学语言描述现实世界所依赖的思想,对于现实对象,为了达到特定的目的,根据内在的规律用适当的数学工具将现实对象转化为数学结构。在小学数学中"工程问题"课例具有典型数学建模过程,从经历"现实问题—建立模型—应用模型"过程中渗透模型思想,可积累数学活动经验,感悟模型思想的本质。

Mathematical model thinking refers to the use of mathematical language to describe the thinking that the real world relies on. For real objects, in order to achieve specific goals, use appropriate mathematical tools to transform real objects into mathematical structures according to internal laws. In primary school mathematics, the "engineering problem" lesson has a typical mathematical modeling process. From the experience of "realistic problems-model building-application model", model ideas can be infiltrated, and experience in mathematical activities can be accumulated and the essence of model ideas can be realized.
