《数学课程标准》指出:“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,使学生体验从实际背景中抽象出数学问题、构建数学模型、寻求结果、解决问题的过程。”怎样在小学数学教学中把学生学习数学知识的过程当作建立数学模型的过程,并在建模过程中培养学生的数学应用意识,引导学生自觉地用数学的方法去分析、解决生活中的问题?笔者结合自己的教学研究实践,以人教版六年级数学“分数除法”例2“把一张纸的4/5平均分成2份,每份是这张纸的几分之几”为例,从两次转译探讨分析数学建模教学,与同行交流。
The Mathematical Curriculum Standard states: “While presenting mathematics as a result of knowledge and skills, we emphasize the students’ experience and make the students experience abstraction from the actual background of mathematical problems, construct mathematical models, seek results and solve problems Process. ”How to treat students in the process of mathematical knowledge in primary school mathematics as the process of establishing mathematical models, and in the modeling process to develop students’ awareness of mathematical applications, and guide students to consciously use mathematical methods to analyze and solve Problems in life? The author combined his own teaching and research practice, with PEP sixth grade mathematics “score division ” Example 2 “4/5 of a piece of paper is divided equally into two, each is the piece of paper A few ”, for example, from two translation to explore mathematical modeling teaching, and peer exchanges.
