Research On The Application Of GeoGebra Software In Mathematics Graphics And Geometry Teaching In Junior Middle School

Education informationization in education leading comprehensive,dynamic,persistence,the MDC,are the backbone of the power education modernization,in mathematics,using the modern education technology to improve the effect of mathematics teaching research have mushroomed,among them,the knowledge of the graphics and geometric module has the characteristics of high abstractness,strong logicality,which requires the teaching process to be specific,intuitive,traditional school education for middle school students learning is not only bad for students to master knowledge of the mechanical calculation and more weaken the desire of students to learn mathematics.Therefore,it is necessary to apply information technology in mathematics teaching research.Geogebra software has a powerful function of combining numbers and shapes.In teaching,the complex knowledge can be intuitionized and vivid situations can be created through this function,and the complex and abstract content in mathematics can be broken down one by one.This study excavates the functions and characteristics of Geogebra software and studies the teaching strategies of mathematics graphics and geometry in junior high schools,in order to optimize the mathematics teaching mode and promote the in-depth unity of information technology and mathematics.In this paper,first of all,the background and significance of the research are expounded,and the basic ideas and research methods of the research are determined.Secondly,it makes a detailed review and review of relevant literature,analyzes the application status of Geogebra software in teaching,determines the geometric intuitive ability as the main evaluation basis of teaching effect,and divides it into levels.Thirdly,from the two aspects of teachers and students to L school junior middle school mathematics teaching status investigation and research,collect and analyze data,summarize the status quo;Based on the analysis of the teaching requirements of graphics and geometry in the new curriculum standard,the emphasis is to illustrate the advantages of Geogebra applied in mathematics teaching with examples,design Geogebra teaching resources and teaching activity program,and select the Pythagorean theorem,axisymmetry and coordinate change and direct proportion function as typical cases for research.From the aspects of teaching practice,walked into the classroom,classroom teaching with GeoGebra software,progressive transformation in the three rounds of teaching practice,improve teaching plan,the teaching effect investigation,evaluation using GeoGebra software to the teaching effect,analysis data,after the author has put forward using GeoGebra software for mathematics teaching strategy: create visual situation,help students to explore regularity;Establishment of mathematics "experiment course" to improve students' operational ability;Analyze the teaching material deeply,construct the efficient classroom;Skillfully using the combination of numbers and shapes,abstract into intuitive;Establish tool awareness and promote appropriate balance.The research proves that using Geogebra software to teach graphics and geometry can significantly improve the teaching effect,which is reflected in the improvement of students' learning interest,learning enthusiasm,beginning to be interested in the operation of information technology,and the improvement of students' academic performance to different degrees.It innovates on the traditional classroom teaching mode,integrates Geogebra software into mathematics teaching,and cultivates a group of teenagers with innovative practice ability and cooperative exploration consciousness.
