Exploration And Application Of The Geometer's Sketchpad In The Junior High School Mathematics Teching

With the rapid development of science and technology in the 21st century,information technology has greatly promoted the development of human society and deeply affected all kinds of industries.Mathematics,as a subject with a wide range of applications,naturally has great hopes for the progress of information technology.Mathematics education expects that information technology can inject strong vitality into it and make abstract mathematics easy to understand.It can make the study of mathematics more interesting.The geometric sketchpad as an excellent educational software,very suitable for mathematics teaching and learning research.In math class,the teacher use geometric sketchpad,can greatly improve the efficiency of teaching,arouses student's study enthusiasm,build the harmonious interaction between teachers and students class atmosphere,At the same time,using the geometric sketchpad can greatly reduce the students'learning difficulty,stimulate students' interest in learning,help students to carry out the math problem.This paper mainly includes five parts.The first part mainly describes the background,purpose and significance of the research,and the research methods to be adopted to carry out the research:The theoretical basis of the research is explained,and the function of the geometric drawing board is briefly introduced;The third part focuses on the application of geometric Sketchpad in middle school mathematics teaching,respectively from the use of geometry sketchpad to middle school plane geometry teaching,using geometry sketchpad to middle school function teaching.Using geometric sketchpad to solve the practical problems related to the function of the three aspects of the explanation,a total of 12 topics,3 teaching examples for practical analysis;the fourth part is the experimental results and analysis.First of all.,the results of the two mathematical tests were compared and analyzed in the experimental class and the control class,and the conclusion was drawn.Secondly,the students in the experimental class who used geometric drawing board for mathematics teaching were investigated by questionnaire,and the results of the questionnaire were seriously analyzed.Statistical analysis;The fifth part is the review and prospect of this subject research.It summarizes the whole paper and puts forward some suggestions on how to use geometry sketchpad to teach middle school mathematics.Meanwhile,it also puts forward some deficiencies and directions for this research in the future.The purpose of this paper is to explore the use of geometry sketchpad in mathematics classroom teaching in middle school,hoping that the present situation of mathematics classroom teaching in junior high school can be changed and a new way of thinking can be provided for the classroom teaching of mathematics teachers in middle school.Improve the quality of classroom teaching,and make geometric sketchpad become an indispensable tool for teachers to teach.
