The Practice And Research Of Geogebra In High School Trigonometric Functions Teaching

Today's society,science and technology continue to innovate and develop,science and technology in constant renewal.The information technology,which takes computer and network technology as the core,is also widely used in every field of our life and work,and brings new opportunity and new challenge to education and teaching.The application of information technology and mathematics to the teaching practice has fostered students ' ability to acquire knowledge actively and to explore it.In the view of modern education,students as the main body,teachers as the leading,the use of information technology to enable students to achieve all-round development.Trigonometric functions are the key points of study in high school mathematics and have a very important position.Students in the study of trigonometric functions,more difficult,less efficient learning,often ineffective.Using Geogebra and trigonometric function to combine teaching of course,it can reverse the deadlock between teachers and students,and can bring new ideas,new ideas and efficient teaching methods to the teachers,which can bring effective learning strategies to students,improve students ' interest in learning Maths,enhance students ' finding problems,The ability to explore and solve problems,to promote the development of students ' abstract thinking ability.This paper is divided into five chapters:The first chapter expounds that the integration of information technology and mathematics curriculum is the need of social development and the new requirements of the new curriculum reform.This paper briefly describes the characteristics of the Geogebra mathematical Software,and studies the purpose and significance of the research,research methods,research ideas and the current situation of the integration of information technology and curriculum.The second chapter expounds the related research outline of this paper.including Geogebra mathematical software overview,"Integration " and "lesson example " Concept definition and related educational psychology Rielen basis.The third chapter expounds the present situation analysis of the teaching and learning of trigonometric function;Geogebra the relevant principles of the integrated course example,the application of Geogebra to implement integrated trigonometric functions,including arbitrary angle lesson,sinusoidal function Image formation course and cosine function image formation course.The fourth chapter is the core part of this paper,the experimental research on the teaching of Geogebra and trigonometric functions,and the data of experiment(teaching practice and questionnaire)are processed and analyzed,and the relevant conclusions are drawn.The fifth chapter has carried on the reflection and the prospect to the curriculum conformity lesson example practice.Analysis of the deficiencies of the Institute and Prospects for future research.
