| The booming development of information technology has promoted the change of education methods and prompted education to develop in the direction of informatization.In order to realize informatization in education,the state has introduced various policies to promote the reform of informationization in education teaching.The “Curriculum Standards for Compulsory Education in physics”(2022 Edition)also proposes to integrate information technology with physics teaching to effectively help students learn.Junior high school physics is an important course,which is relatively simple compared to high school physics,but it has a certain level of abstraction in comparison to students’ level of cognitive development.Due to the contradiction between the abstract nature of physics teaching content and the visual thinking level of students,it is important for physics teachers to use visualization and illustration as much as possible in the teaching process to help students better understand.Visualization and illustration of physics knowledge rely heavily on the support of information technology.Geo Gebra(GGB),a dynamic educational software,is a free and open-source software with powerful data computation capabilities.It combines“numbers” with “shapes”,visualizes abstract concepts,animates static laws,and simulates physics experiments.These features of GGB demonstrate that it is a very suitable software for visualized teaching.This study explores the specific methods and processes of assisted physics visual teaching based on GGB software: First,consult literature to understand the status quo of GGB software in physics teaching and the status quo of visual teaching in physics;The second step,aiming at the difficulties encountered in the teaching of physics concepts,laws,experiments and exercises,GGB software is used to develop a series of teaching courseware to visualize these physics contents,break through teaching difficulties and help students understand physics knowledge.The third step,based on the developed courseware and visual teaching concept,design teaching cases;Finally,from the aspect of teaching practice,the case design is applied to teaching practice,and the effect of GGB visual teaching is analyzed by questionnaire survey and educational experiment.The results of the questionnaire survey show that visual teaching with GGB software can improve students’ learning interest and promote students’ mastery of physics knowledge.In order to further verify the effect of visualization teaching with GGB software,two parallel classes were selected for teaching practice.SPSS software was used to test the significance of students’ post-test results,and it was found that GGB software could indeed promote students’ understanding and mastery of physics knowledge,especially the understanding of image problems.Based on the use of GGB to make courseware and teaching practice experience,the author puts forward some suggestions for using GGB software to carry out visual teaching,that is,model construction should conform to the real situation and the law of students’ cognitive development,courseware making should be problem-oriented,GGB software should be suitable for segment teaching,attention should be paid to mobilizing students’ enthusiasm and rational use of existing GGB resources.The innovation of this study is that GGB software is used to develop and produce relevant cases,which provides certain reference value for front-line teachers to carry out visual teaching. |
