| As IT used in the secondary school teaching, especially in the secondary school mathematics teaching, the students are getting more confused. What is the use of math especislly the function in the secondaru school?Can the mathematical knowledge be used to solve practical problems in the real life? Can we solve the practical problems be based on the mathematical knowledge in the secondary school,and get helpd from the simple IT? If so, then how can we achieve it step by step?In order to solve the practical problems by mathematical knowledge, experts and scholars in the United Kingdom, first proposed the idea of mathematical modeling. They want to measure the quanty of examples in the real life by the modern means,and promote the production and learning by study and abstract the examples in the real life.The idea of using the IT in the mathematical model has affected the people deeply abroad especially in developed countries in the western countries.Considering our current educational philosophy and guiding ideology, mathematical model has neighter been developed fully in higher education,nor been denelopped in the secondary schools whose purpose is exams.As the primary first-line math teachers, we have the responsibility and obligation to innovative methods of validation and demonstration of basic mathematics education for China’s national conditions. The problem of how to solve the problem of the real teaching theory combining with practical problems has become a big problem of secondary school mathematics education, and a bottleneck in the development of mathematics education. The topic of this paper is verifying the practicality of a quadratic function of the middle school mathematics in everyday life by IT. The writer analysis and verify the mathematical modeling,not only solving the problems of deficiencies of the current mathematical modeling in the primary secondary education in China, but also improving the students’interesting of mathematics and the awareness of the practicality of mathematics of the students. To achieve the above target, the thesis has the following steps:1, Select the examples from real-life which is linked with this paper. Apply the basic abstractive mathematical simulation function.in the current secondary schools from the selected examples2, Guide students to descript of the abstract function model, applying the most simple middle school math functions and the knowledge-based modern information technology,and the most common application of secondary school mathematics teaching practice software-Geometer’s Sketchpad.3,Analysis the abstracted function by the simulation software which close to the reality.4, Eventually get the correct and reasonable scientific conclusion of the papers,by analysising the different stages of the real life results and computer simulation results,comparing different circumstances, and complement each other amendments.This article is based on the local teaching environment and professors crowd, and apply ready-made mature mathematical thinking test demonstration. The test is not only brought the advantages of traditional mathematics teaching, but also give the students an accurate understanding of mathematics and IT in the practical application of real-life pre-boot. Bring a solid foundation for students for entering a higher level of mathematics learning. The difficulty in this article:the combination of IT and mathematics, mathematics and real life, simulating the mathematical results and process in the real life by IT,the complement and correction of simulation and realistic results. |
