义务教育课程标准提出:数学教学要在呈现作为知识与技能的数学结果的同时,重视学生已有的经验,让学生体验从实际背景中抽象出数学问题、构建数学模型、得到结果、解决问题的过程。从这个角度讲,数学模型是数学学习中不可缺少的元素,学生的数学学习过程,其实就是一个不断地建模和用模的过程。数学建模能够引发小学生对数学学习的兴趣,提高学习数学的效率。由于小学生 The standard of compulsory education curriculums put forward that mathematics teaching should take the experience of students as a mathematical result of knowledge and skills, let the students experience abstraction of mathematical problems from the actual background, construct mathematical models, get results and solve problems process. From this perspective, the mathematical model is an indispensable element in the mathematics learning. The students’ mathematics learning process is actually a process of constant modeling and mold-making. Mathematical modeling can arouse pupils’ interest in mathematics learning and improve the efficiency of learning mathematics. Because of pupils
