The Study And Analysis Of Mathematical Model Construction Of Application In Junior High School

Mathematics comes from people's lives.Since ancient,mathematics has been widely used in people's production and life.It has always been an important tool to promote social advancement.At the beginning of the 21 st century,all countries have emphasized the application of mathematics to different degrees,especially the construction of mathematical models to solve practical problems.This is to ask the new age students to have certain modeling abilities,modeling skills.It is one of the important tools to cultivate students' application ability and an important way to improve students' modeling ability.This article built,sorting,sums up the literature about modeling,set the research problems: One is to investigate the situation that middle school students are building in the current situation,and this study will determine the four layers of the model of the model,based on the mathematical modeling span and the mathematical application of the problem,then we'll do the test;the second is to prepare the questionnaire,the main survey student's learning interest,attitude,habit of reading,habit of analysis,combined with the analysis of the test the draw at this stage the problem to the junior middle school students in the process of modeling and the reasons,There are shortcomings that reading ability is insufficient;analysis ability is insufficient;The ability of combining charts and images to build models is weak;Cannot use words,date to describe problem;The lack of mathematical modeling knowledge is not based on the student model.And aiming at the shortcomings of the students built the model make effective learning advice:1.Cultivating students' good reading habits,improving students' reading ability;2.Cultivate the students' analysis ability,improve the relations between the number of obtained from the actual problem ability;3.Focus on the application of the chart and strengthen the modeling ability of students;4.Focus on carrying out mathematical activities to develop students' ability of discussion;5.Focus on the students' modeling knowledge culture,and integrate mathematics modeling into teaching.In teaching,the teacher should cultivate the student's modeling ability in the process of solving the problem,so as to make the process of the student's pot modeling.This will help students deal with more complex life and production problems.Hope that through the research of this paper,a line can make teachers realize the importance of the application of model building,also can offer some effective measures for them after teaching.
