The Application Research Of GeoGebra In The Teaching Of Graphics And Geometry In Junior High School

Since the 21 st century,information technology has developed rapidly,and its impact on the field of education has been expanding.The importance of educational informatization has become increasingly prominent in the process of educational reform and development.The integration of information technology and education has gone through four stages of "start","application","integration" and "innovation".The integration of information technology and education in China is still at primary application and integration stage.Information technology not only innovates the traditional education model,but also creates a new teaching and learning environment.Mathematics is the main subject in junior middle school.Improving mathematics teaching mode and effectively promoting the deep integration of information technology and mathematics education will have a positive impact on our mathematics teaching.The purpose of this study is to design the application of GeoGebra software in the teaching of graphics and geometry in junior high school by combining GeoGebra software with existing teaching resources,and to use SPSS 19.0 data analysis software to statistics and analyze the experimental data and questionnaire data,to verify the positive impact of GeoGebra software on the teaching of graphics and geometry in junior high school from both theoretical and practical aspects.The research process and methods are as follows:The object of this experiment is two parallel classes of seventh grade.The experimental group uses GeoGebra to assist the teaching of graphics and geometry,while the control group uses the conventional teaching method.The teaching experiment lasts for one semester.The teaching content is the first volume of the seventh grade of junior middle school mathematics in the edition of Beijing Normal University.This experiment uses SPSS 19.0 data analysis software to analyze the experimental data and questionnaire data.Based on Van Hill's theory of geometric thinking level,attention theory and audiovisual education theory,the implementation scheme is designed.Through the real teaching practice,this study shows that the use of GeoGebra software to assist the teaching of graphics and geometry in junior high school can enhance students' interest and enthusiasm in learning,cultivate students' mathematical and logical intelligence and visual space awareness,and then improve students' mathematics learning performance and teaching efficiency.The research results fully prove that: GeoGebra software-assisted graphics and geometry teaching in junior high school plays an important role in optimizing classroom teaching and improving teaching efficiency,which is worthy of vigorous promotion and application in the field of graphics and geometry in junior high school.
