摘要
从实际问题情境中抽象出数学问题、构建数学模型、寻求结果、解决问题,是学生应用数学知识解决实际问题的一种能力体现。本文基于对构建数学模型的理解,结合天津两道中考经典试题,围绕构建几何模型,解决实际测量问题;构建函数模型,处理图象信息问题,进行专题评析。充分利用教材资源、构建数学模型、解决实际问题,是有效落实《义务教育数学课程标准(2011年版)》的重要方面。
The article discusses that it is an ability for students to solve practical problems by drawing a correct conclusion from objective facts,building mathematical models,seeking for results and solving them.According to two classic questions from Tianjin's previous high school entrance examination,this article,which is based on the comprehension of building mathematical models,presents the methods of solving actual measurement problems focusing on building a geometric model.Also,this paper introduces how to deal with the problem of image information by building the function model,and carries on the special evaluation and analysis.The purpose of the study is to make good use of teaching resources to build mathematical models in order to solve practical problems.It is important to follow the basic idea and spirit of basic education curriculum reform and effectively implement the basic requirements of Compulsory Education Mathematics Curriculum Standards(2011 Edition).
