数学建模是一种数学思考方法,简单地说就是把实际问题用数学语言抽象概括,从数学角度来反映或近似地反映实际问题,得出的关于实际问题的数学描述。在这一过程中,我们需要培养学生的抽象、简化思维等。《基础教育课程改革纲要(试行)》对于课程实施和教学过程有明确的要求:“教师在教学过程中应与学生积极互动、共同发展,要处理好传授知识与培养能力的关系,关注个体差异,满足不同学生的学习需要。”《分式》一章是在学习了整式的运算和因式分解后,从分数的概念到分式的概念,从分数的基本性质到分式的基本性质,从分数的通分、约分及运算到分式的通分、约分及运算,都是用类比的数学模型进行
Mathematical modeling is a kind of mathematical thinking, simply put the practical problems in mathematical language abstraction summary, from the mathematical point of view to reflect or approximately reflect the actual problems, drawn on the actual problem of mathematical description. In this process, we need to cultivate students’ abstraction and simplify thinking. “Basic Education Curriculum Reform (Trial)” for the implementation of the curriculum and teaching process has a clear requirement: “teachers in the teaching process should actively interact with students and common development, to deal with the transfer of knowledge and ability to cultivate the relationship between the attention of individuals Differences, to meet the learning needs of different students. ”“ Fraction ”chapter is in the study of the operation of the integer and factorized, from the concept of fractional to fractional concept, from the basic nature of fractional to fractional basic Nature, from the points of division, about points and operations to the fractional division, about points and operations, are used analogical mathematical model
