建立数学模型需要学生对现实问题深入细微的观察和分析,对其中数量之间的关系、结构进行抽象、提炼,因此需要教师更多地关注建模的过程。一、关注概念的生成过程,建构方法模型数学概念是小学数学基础知识的一项重要内容,是学生理解、掌握数学知识并运用概念解决问题的首要条件。有些概念的生成过程中蕴涵方法因素,应让学生感受到建立模型是一种解决问题重要且行之有效的方法。感悟模型思想,增强通过建模解决问题的意识。
To establish a mathematical model requires students to observe and analyze in-depth and meticulous real problems and abstraction and refinement of the relations and structures among them, so teachers should pay more attention to the modeling process. First, pay attention to the concept of the generation process, building the method model Mathematical concept is an important part of the elementary knowledge of mathematics in primary schools, students understand and master the mathematical knowledge and the use of concepts to solve the problem of the primary conditions. Some concepts in the process of generating methodological implications, should allow students to feel that the establishment of the model is an important and effective solution to the problem. Comprehend the model idea and enhance the awareness of problem-solving through modeling.
