Research On GeoGebra's Influence Of Pupils' Spatial Imagination Ability In Mathematics Learning Of Primary School

As the "New Curriculum Standards" has higher requirements for school education in the new era,in "Graphics and Geometry",one of the important primary school mathematics core qualities should be cultivated,and the students' spatial imagination ability should be improved correspondingly.With the continuous development of education informatization,updated and iterative information technology has been integrated into school education:it plays an indispensable role in assisting elementary school mathematics teaching and helping to solve teaching problems.Due to the abstraction of mathematical knowledge and the technical limitations of traditional teaching methods in cultivating students' spatial imagination ability:some students will have difficulties in spatial imagination,so their spatial imagination ability cannot be well cultivated.After analyzing and interpreting the core literacy of primary school mathematics,the relationship between space concept,one of the core literacy of primary school mathematics,and spatial imagination ability is obtained.According to the "New Curriculum Standard" and the predecessor's level evaluation standards for primary school students'mathematics space imagination ability,the results of this study are obtained.The three requirements of the evaluation level of pupils' mathematical spatial imagination ability provide standards for comparing the training degree of spatial imagination ability with experimental data.Graphic geometry tool GeoGebra dynamic math platform is a free dynamic platform with multiple courseware resources to make courseware.Teachers can use 3D calculators,CAS calculators,etc.for free.There are all flat and three-dimensional mathematical drawing tools on the platform:through three-dimensional The rectangular coordinate system presents points,lines,surfaces,bodies,and various function images.Teachers can draw online,or make courseware for offline use,upload it to resources,or use classroom resources already on the platform for free.The research is based on GeoGebra's 3D calculator and classroom resources to assist teaching in order to improve students' spatial imagination ability.The research methods are literature research method and quasi-experimental research method.The experiment compares the teachingeffects of GeoGebra-assisted elementary school mathematics "Graphics and Geometry" concept class teaching,exploring activity class and traditional teaching aids.The experimental group and the control group are tested for 3 primary school students' spatial imagination ability requirements.In the experimental research,whether the open classroom resources in GeoGebra assist the teaching of the "Graphics and Geometry" activity exploration course,whether the 3D calculator in GeoGebra assists the teaching of the"Graphics and Geometry" concept lesson is an independent variable,and the dependent variable is students' spatial imagination ability based on the three requirements of spatial imagination ability under the evaluation standard.The analysis of experimental data shows that there is a significant difference between the GeoGebra3D computer-assisted graphics concept lesson and the students' spatial imagination ability under the traditional teaching,and the GeoGebra classroom resource-assisted activity exploration course and the traditional teaching students' mathematical spatial imagination ability are significantly different.It is concluded that the 3D calculator and classroom resource-assisted teaching in GeoGebra software can improve the students' spatial imagination ability compared with traditional teaching,thereby cultivating the core quality of students' spatial concept.
