Research On The Cultivation Of Intuitive Imagination Literacy For High School Students Based On GeoGebra ——Take The "Stereo Geometry Preliminary" As An Example

The new round of curriculum reform clearly requires that the core literacy of the subject should be taken throughout,and visual imagination as one of the six core qualities,its importance cannot be described.The Ministry of Education promotes the "Education Informatization 2.0 Action Plan",and the integration of information technology into the classroom has become a hot topic in the new era.At present,the integration of information technology and the core literacy of disciplines is still in the exploration stage.This research effectively connects the core literacy,information technology and educational psychology.The main problems are as follows:（1）how is the cultivation of high school students at the present stage?（2）How can GeoGebra effectively connect with the formation process of students’ intuitive imagination quality?（3）What is the impact of the processing mode of intuitive imagination literacy under GeoGebra environment on students’ intuitive imagination literacy?Using the survey of questionnaires and interviews,Understand the current situation of teaching and learning of intuitive imagination,three-dimensional geometry and information technology;Apply information processing theory and mathematical image thinking theory to analyze the formation process of intuitive imagination quality,Combined with the functional advantages of the GeoGebra software,Construct the processing mode of intuitive imagination quality under the GeoGebra environment;Based on the current situation survey results and the audio-visual teaching theory,Put forward the corresponding teaching principles,With the chapter of "stereoscopic geometry preliminary" as the knowledge carrier,Design of teaching cases;Applied to teaching cases to teaching practice,Through the qualitative and quantitative analysis of the experimental results,Verify the suitability of GeoGebra and visual imagination literacy cultivation;Combining the investigation and the experimental results,To provide teaching suggestions for front-line teachers to apply GeoGebra to improve students’ intuitive imagination literacy.The study shows that GeoGebra is applied to stereo geometry class,It has a certain effect on improving the level of students’ intuitive imagination and quality,In the prototype intuitive stage,GeoGebra’s fast mapping and dynamic demonstration capabilities to create a variety of situations,Help students to form a spatial geometric representation,Establish the connection between graphics and physical objects,Cultivate the geometric and intuitive ability;In the representation visual stage,The sliding bar function of GeoGebra software can dynamically demonstrate the formation process of stereo geometry concepts,theorems,The transformation process of presenting number and shape synchronization,The idea of osmosis number and shape combination,Help students understand conceptual theorems;In the imagination visual phase,GeoGebra’s 3D display and graphic transformation feature,Help the students to build mathematical models,Improve students’ spatial imagination ability.Moreover,the integration of GeoGebra into stereoscopic geometry class can effectively solve the spatial structure and dynamic changes that students cannot imagine stereoscopic geometry,and improve students’ learning enthusiasm and classroom efficiency.
