GeoGebra Assists The Rural High School Stereo Geometry Teaching Strategy Research

Solid geometry is one of the important contents of high school mathematics learning and college entrance examination.Some rural senior high school students have difficulty in learning this part,which is manifested in poor understanding and application of concepts and propositions,low test scores,fear and boredom in learning.The main purpose of this study is to improve the teaching of three-dimensional geometry in rural high school mathematics,improve the teaching quality of threedimensional geometry,and improve the current situation of three-dimensional geometry teaching in rural high school.Based on this design,this paper first obtains four influencing factors of solid geometry teaching in rural senior high schools through literature analysis and combing previous studies,including spatial perception ability,students' willingness to participate,time utilization efficiency and teachers' expression ability.Based on this,questionnaires and interviews were designed.After questionnaires and interviews were conducted with 120 students and 5 teachers respectively,it was learned that students studying in rural high schools did not cultivate spatial perception ability in the sensitive period,so that the level of graphic construction was not strong.At the same time,due to the lack of interest in mathematics classroom,most students' willingness to participate is not high.However,the low efficiency of time use and the relative lack of expression ability of mathematics teachers are also prominent.In response to the above problems,the article uses GeoGebra software to improve students' spatial perception by using visual graphics.Bringing GeoGebra software as a link to flip the classroom,thereby enhancing students' willingness to participate in teaching.At the same time,with the help of terminal APP to attract students' attention,and then make effective use of classroom time.Finally,the article takes the display graphic as the premise,combines the variable teaching to enrich the rural teachers' expression means.It has been tested that teachers can reduce the abstraction of knowledge by using GeoGebra software to aid stereometric teaching,and thus make up for the deficiency of students' spatial perception ability.At the same time,it can improve students' willingness to participate,strengthen the efficiency of time utilization and optimize teachers' ability to express themselves.
