考试结束了,学生涌出考场,边走边议论,“今天的应用题,我没有想到它是什么模型”“我又没有理解题意,不知道如何建立数学模型”“题目中的参量较多,不知道选择哪一个作为自变量”“应用题的数学模型究竟有哪些,我背了前几年的数学模型,但一到考场里就全忘记了,不知道怎样寻找几个量之间的联系”……我为此邀请几位学生针对数学应用题的建模问题进行交流,旨在通过对几道应用题的分析,引导学生寻找变量与 The exam was over, the students poured out of the examination room, walked and talked about, “Today’s application questions, I did not think of it is what model ” “I do not understand the title, do not know how to create mathematical model ” I do not know which one to choose as an independent variable “” What is the mathematical model of the application? I am back a few years ago, the mathematical model, but to the examination room all forgotten, do not know how to find A few of the links between the amount of "... ... I therefore invited several students to address the mathematical modeling problem of mathematical problems to communicate, aims to analyze the application of several questions to guide students to find variables and
