Research On GeoGeBra Assisted High School Solid Geometry Teaching

In the context of the continuous development of information technology,the level of educational resources has been greatly improved,and modern multimedia teaching equipment has gradually become popular,providing a good soil for teachers to use software to assist mathematics teaching.The content of three-dimensional geometry in high school puts forward further requirements for students' intuitive imagination and other abilities.To achieve good teaching results,more and more mathematics teachers have chosen to use mathematics software to assist teaching.As a free dynamic math software,GeoGebra is powerful and easy to operate,especially its powerful 3D function,which can visually show abstract spatial geometry to students,and perform dynamic demonstrations when necessary,which not only reduces teachers' teaching Difficulty,it can also reduce the cognitive load of students and improve their spatial imagination ability.However,in actual teaching,there are a series of problems such as poor understanding of GeoGebra software by mathematics teachers,low frequency of use,and poor use effect.Finding and solving these problems can truly improve the effectiveness of GeoGebra software in assisting solid geometry teaching.It brings out the great potential of GeoGebra software in solid geometry teaching.Based on the above thinking,this research will take the high school solid geometry teaching as an example,and conduct the research according to the following ideas: First,use the literature research method and read a lot of related literature to understand the research status of GeoGebra software-assisted mathematics teaching at home and abroad.Based on constructivist learning theory,computer-assisted teaching theory,and cognitive load theory,from teachers' familiarity with GeoGebra software and frequency of use,teachers' attitudes and views on using GeoGebra software to assist teaching,and teachers' use of GeoGebra software to assist solid geometry The five dimensions of the teaching method,the main problems and influencing factors of the teacher's use of GeoGebra software to assist the teaching of solid geometry,and the teacher's learning attitude to the GeoGebra software,prepare the questionnaire and draw up the teacher interview outline.Afterward,I took mathematics teachers from three key high schools of the same level in Harbin,Heilongjiang Province as the research objects,conducted questionnaire surveys and teacher interviews,and observed the actual situation of teachers using GeoGebra software to assist solid geometry teaching.After the investigation,summarize and analyze the current teaching situation and find out the existing problems.Through the above research,the author summarizes the four principles for teachers to use GeoGebra software to assist solid geometry teaching: integration principle,rationality principle,active participation principle and dynamic principle;and six points for teachers to use GeoGebra software to assist solid geometry teaching Suggestions: find the combination of GeoGebra software and the content of the textbook,pay attention to the role of writing on the blackboard,make reasonable use of network resources,make full use of fragmented time,pay attention to the dominant position of students,pay attention to the cognitive load of students,and strengthen software operation training.
