数学模型是对实际问题的数学化,也就是把某种事物系统的主要特征、主要关系抽象出来,利用数学语言和符号概括地或近似地表达出来的一种数学结构。从广义上来讲,数学模型一般分为三类:概念型数学模型、方法型数学模型、结构型数学模型。在课堂教学中,教师要根据不同数学问题的特征,通过引导学生进行分析与综合、比较与分类、抽象与概括等思维活动初步构建模型,然后对数学模型进行具体化、系统化的应用和拓展。下
Mathematical model is the mathematical problem of the actual problem, that is, a kind of mathematical system that abstract the main features and main relations of the system of things, and summarize or approximate them by mathematical language and symbols. Broadly speaking, mathematical models are generally divided into three categories: conceptual mathematical models, mathematical models of methods, structural mathematical models. In the classroom teaching, teachers should initially construct the model according to the characteristics of different mathematical problems by guiding the students to analyze and synthesize, compare and classify, abstract and summarize the thinking activities, and then to concretely and systematically apply and expand the mathematical model . under
