Empirical Research On Junior Middle School Mathematics Teaching Based On Geometric Sketchpad

In the traditional junior high school mathematics classroom,teachers pay too much attention to the formalization and systematization of mathematics,ignoring the process of mathematical knowledge formation,that is,paying too much attention to the deductiveness of mathematics and neglecting the inquiry of mathematics.The mathematics classroom lost its lively and lively,which caused many students to have insufficient interest in mathematics.In order to change this phenomenon,many modern educational techniques have been introduced in the mathematics classroom,such as the geometric sketchpad explored in this article.It turns static pictures into dynamic,abstract things become concrete,making math classes more interesting.However,many teachers still adopt the teaching method of “teacher speaking,student listening” in teaching,using geometric drawing board to demonstrate knowledge points,and the definition of knowledge points using this tool is vague.This paper proposes a self-exploration teaching model based on relevant theories,conducts experimental research and draws conclusions,in order to explore the teaching mode suitable for junior high school mathematics,and hopes to provide some mathematical references for the majority of frontline teachers.The full text consists of six chapters:Chapter One Introduction.The domestic and international research on the topics to be studied in this paper mainly includes the background of the research,the content of the main research,the main methods used in the research and the relevant significance of the research.The second chapter is the theoretical basis and concept definition.A detailed introduction to the theoretical basis of the article and how it is applied to the research in this paper.Geometric Sketchpad is a detailed conceptual definition of the teaching software,including functional,functional and technical applications.A brief introduction to a self-exploration teaching mode based on geometric sketchpad.The third chapter is the application status of geometric drawing board in junior high school mathematics teaching.The content adapted to the teaching of geometric drawing board is defined according to the principle.Questionnaires and interviews were conducted among school teachers using geometric drawing board teaching in Sanmenxia City,Henan Province,to analyze the situation and problems in using geometric drawing boards at this stage.The fourth chapter is the teaching design and experiment of geometric drawing board in junior high school mathematics teaching.Based on the relevant theory,the self-inquiry teaching mode is proposed and applied to the teaching experiment.The second class(1)of the Experimental Middle School of Sanmenxia City,Henan Province is used as the experimental class.The teachers use the self-inquiry teaching mode to teach,(2)the class teacher Half-semester teaching is carried out using a traditional teacher demonstration based on geometric sketchpad.The fifth chapter analyzes the experimental results of geometric drawing board in junior high school mathematics teaching.Questionnaires for students and teaching,analysis of the results of the survey and conclusions.Chapter VI,conclusions and prospects.Summarize the results of this study,sort out the problems encountered by the Institute,and look forward to future research.
