数学模型是近似表达现象特征的一种数学结构。设计数学模型的过程就称为数学建模。建模过程包括四个主要阶段:一是理解问题,找出影响该问题的重要因素;二是简化、假设、猜测重要因素之间的关系并得到一个数学模型;三是求解模型,得出初步结果;四是检验模型(必要时修改)。在上述几个步骤中,最关键也是学生最头疼的就是第一步。一、学生学习建模的困难1．对完成建模信心不足。与教材中的纯数学问题 Mathematical model is a mathematical structure that approximates the phenomenological phenomenon. The process of designing a mathematical model is called mathematical modeling. The modeling process includes four main stages: one is to understand the problem and find out the important factors that affect the problem; the other is to simplify, assumptions, guess the relationship between the important factors and get a mathematical model; third is to solve the model, come to the initial Results; Fourth, test model (modified if necessary). In the above steps, the most critical is the most troublesome students is the first step. First, students learn modeling difficulties 1. Lack of confidence in completing the modeling.
