A Comparative Study On The Applicability Of Geometry Sketchpad And GeoGebra In Junior Middle School Mathematics Teaching

Information technology is one of the important ways to fundamentally change the way of mathematics learning.It must be applied fully.The "compulsory education mathematics curriculum standard(2011 Edition)" describes how to use the information technology resources in the "proposal for the development and utilization of curriculum resources".Geometer's Sketchpad and GeoGebra as two powerful mathematical education software resources,have their own distinct functional attributes.However,in junior high school mathematics teaching,the lack of understanding of them and the lack of development and utilization will inevitably affect the use value of educational technology.Therefore,it is of great theoretical and practical significance to study the applicability of Geometer's Sketchpad and GeoGebra in junior high school mathematics teaching.This study adopts literature analysis,questionnaire survey,interview and statistical analysis to make a comparative study.First of all,we summarize and summarize the research status of Geometer's Sketchpad and GeoGebra in China by literature analysis,and point out the necessity of writing this paper.Secondly,using the questionnaire survey method to master the use of Geometric Sketchpad and GeoGebra two software in junior middle school mathematics teaching,teachers,use satisfaction,and the difficulties encountered by teachers in using two kinds of software for courseware or integrable ware making and classroom teaching.Thirdly,the number of chapters and knowledge points in the textbook is analyzed,and five representative cases are selected from the three parts of "number and Algebra","figure and geometry" and "statistics and probability".The design of integrable parts follows five optimization principles:information packing principle,space proximity principle,time Principles of proximity,consistency and dynamic interest.Finally,interviews were conducted among students and teachers.The result of student interview reflects the degree of students' recognition of the results of the two software,and the result of teacher interview reflects the difficulty of the two software in the design and production of the integrable ware.The main conclusions obtained in this study are as follows:(1)the difference between the use rate of GeoGebra and the geometric sketchboard in junior middle school is obvious.The teachers generally affirm the teaching value of the mathematical software,and the popularization of the GeoGebra software is beneficial to the teachers to improve the teaching efficiency.(2)the geometric sketchboard is obviously superior to GeoGebra in the rendering effect of graphics,characters and symbols;the geometric sketchboard has advantages over GeoGebra in the teaching of plane geometry;GeoGebra has an advantage over the Geometric Sketchpad in the teaching of function,stereoscopic geometry,probability and statistics.Based on the conclusion of the above study,this study suggests that the promotion of education technology should be carried out in the whole process of teachers' pre service and vocational education,and teachers can understand the functional features and application scope of the geometric sketchpad and GeoGebra.At the same time,teachers should take the initiative to learn the related knowledge of Geometer's Sketchpad and GeoGebra,improve their operation level,and integrate two software in teaching and take their respective advantages.
