Research On GeoGebra Based Teaching Practice Of High School Solid Geometry

With the rapid development of information technology,excellent mathematical software such as GeoGebra and Geo Sketchpad are gradually applied to mathematics teaching,among which GeoGebra has greater application value in teaching practice of solid geometry with its powerful and simple 3D drawing function.However,there are few examples of integrating GeoGebra with teaching practice of solid geometry.At the same time,front-line teachers can better understand students’ learning needs.Therefore,more research is needed to provide front-line teachers with teaching strategies and cases of solid geometry based on GeoGebra.This research first discusses the research status quo of using GeoGebra to assist the teaching of solid geometry at home and abroad,clarifies the concept of GeoGebra integrable ware,and discusses the theoretical support required by this paper,namely,constructivism theory and multiple representation theory.Then this research introduces GeoGebra and its application value,mainly including the basic description of the use and operation of the software and the software interface.At the same time,it describes the general development process of the software,the software characteristics in the teaching practice of solid geometry,and compares and analyzes the advantages and disadvantages of the software with the corresponding teaching functions of the Geo Sketchpad.Then,through the research method of questionnaire survey,the current situation of GeoGebra’s application in auxiliary teaching in high school solid geometry teaching is analyzed.Supported by constructivism and multiple representation theory,based on the data of the questionnaire,and based on the current teaching situation of solid geometry,five teaching strategies of high school solid geometry based on GeoGebra are proposed:(1)introducing the mode of pre class,in class and after class to improve students’ familiarity and participation in software;(2)Use terminal APP and online resources to improve teaching efficiency;(3)Adopt multiple expression forms of space geometry to enhance the interactive evaluation between teachers and students;(4)Cultivate students’ ability of space drawing through visual display.Then,by repeatedly studying the teaching materials of high school solid geometry,in combination with GeoGebra’s 3D drawing function,corresponding teaching strategies and students’ learning needs,this research gives two teaching cases of new knowledge class and exercise class,which has certain teaching reference value,and gives derivation and expansion of GeoGebra’s teaching application cases in summary and reflection,which is the key content of this research.In order to test the teaching effect of GeoGebra based high school solid geometry,this research conducts a data comparative analysis of the effect of traditional teaching of solid geometry and GeoGebra based teaching by controlling a single variable education experiment.Finally,it is concluded that the GeoGebra based teaching strategy of high school solid geometry is more helpful to students with strong and weak mathematical learning ability,and is beneficial to teachers and students to improve the teaching efficiency of solid geometry.The practical application of GeoGebra in the teaching of solid geometry deserves more researchers’ efforts!...
