Research On GeoGebra Software Assisted High School Physics Kinematics Teaching Based On Scaffolding Teaching Mode

With the reclassification of curriculum objective dimensions in the Physics Curriculum Standards for Senior High Schools(2017 edition,2020 revision),more attention is paid to the cultivation of students’ autonomous learning ability,the improvement of students’ ability to analyze and process complex data,and the establishment of physical models.Under the background of educational informatization reform,how to integrate information technology and physics classroom effectively is an urgent problem for physics teachers to solve.Scaffolding teaching mode is to use questions,tools and images to build scaffolding between students’ existing knowledge and experience and teaching objectives.With the continuous improvement of learners’ ability,the scaffolding teaching mode is gradually removed to achieve the purpose of cultivating students’ ability of independent inquiry and independent thinking in the process.Therefore,it becomes crucial to select appropriate scaffolding.GeoGebra software,as a dynamic graphics software integrating geometry and algebra,can effectively simplify and visualize abstract knowledge,and make teaching courseware related to high school physics courses,which is also in line with the current background of education informatization reform.Based on this,under the background of scaffolding teaching mode,this research selects GeoGebra software as the tool support,writes two kinds of teaching cases of linear motion and curved motion in high school physics kinematics topic,and tests their effectiveness through teaching practice activities.The main work of this paper is as follows:First,the questionnaire survey is used to understand the situation of students’ physics learning and physics class.The survey results show that the frequency of computer graphics software is low in the current physics class,and students’ understanding and application of complex knowledge need to be further improved.Second,based on the investigation and analysis of the current situation of high school physics kinematics teaching,the principles and corresponding teaching strategies for the use of GeoGebra software as a tool support in teaching are proposed.By selecting the typical models of straight line and curve motion in high school physics kinematics,using GeoGebra software to build tool support and combining teaching principles and teaching strategies to develop teaching design,students can gradually understand complex knowledge,strengthen their ability to apply knowledge,promote their thinking from concrete to abstract,and further build physical models in their minds.Third,to test the effectiveness of GeoGebra software-assisted teaching based on scaffolding teaching mode through teaching practice.The experimental class uses the courseware developed and designed in this study for teaching,while the control class still adopts the conventional teaching mode.After three months of teaching practice,the experimental class has significantly improved in physics learning and attitude in physics class compared with before practice.Compared with the control class,the experimental class improved the dimension of modeling ability.It can be seen that GeoGebra software based on scaffolding teaching mode has certain practical value in assisting high school physics kinematics teaching.On the one hand,it can enhance the interest of physics class and enhance students’ learning interest.On the other hand,using visual computer drawing software as a tool support can help students construct complex knowledge better,deepen their understanding of knowledge,and improve their modeling ability to a certain extent.
