The Application Of Virtual Experiment Technology In Physics Modeling In Middle School

In recent years,with the rapid development of information technology and Internet technology,the teaching system based on virtual reality technology has been attached importance to and applied in the teaching process of junior high school physics,and the application of this technology has created new vitality for the development of middle school physics modeling experiment.This is because virtual experiment technology gives full play to the advantages of high resolution display technology,multi-sensing interaction technology and 3D digitization technology.It can generate more realistic 3D virtual scenes in the process of physical modeling,and then make the scene and users realize real-time interaction,operation and perception of virtual objects.Therefore,the application of virtual experiment technology in middle school physics modeling can improve the teaching effect and experimental performance of physics modeling.In addition,through virtual experiment technology,middle school physics teachers can collect real on-site physical data,and then analyze and process the data in all aspects,and display the data in a diversified way.In this study for the application of virtual experiment technology in high school physics modeling as the subject,the analysis of the related research at home and abroad on the basis of the modeling technology of virtual experiment technology foundation,display technology,interactive technology,explores the function of library,and according to the results of the study,the technique of high school physics virtual experiment modeling scheme.Based on the establishment of modeling objectives and principles as the precondition,the model construction is divided into structure,environment and modeling,and the middle school physical modeling scene is built by frame,detection,scene,camera,rendering,light source,object,detection,coordinate and clicking.The modeling part includes the modeling supported by image and geometric model.The display part is the virtual experimental technology rendering engine installed on the browser side.The interactive part is the "three.js" composed of WebGL,Cult3 D,Java3D and encapsulation.Finally,this study proves the effect of virtual experimental technology in middle school physical modeling through scene change,dynamic connection,switching state,rheostat,bulb and other experiments.The experimental results also show that the creation of a model diagram for each key point of knowledge of middle school physics can help students produce clearer visual effects and better grasp the knowledge of middle school physics.Therefore,the application of virtual experiment technology in middle school physics modeling is particularly important.In addition,this study summarizes the innovation points and deficiencies of experimental development.Based on the experimental results,it reflects on the effect and status of virtual experimental technology after it goes deep into the middle school physics discipline,and then draws optimized teaching Suggestions.
