Design And Development Of Physics Experiment In Middle School Based On Virtual Reality Technology

Due to the current situation of the rapidly developing virtual reality technology which is based on the Web3 D and the virtual experiments which is poorly applied in physics of junior school,I put forward the solution that we develop virtual experiments based on the Three.js.While integrating the theories between the new edition of information technology and the subjects,i also has explored the developing process through the virtual experiments with the Three.js and the problems I came across.Nowadays the documents of the development of virtual experiments which are based on the Three.js is poor,and the references and books are foreign languages related and most of their contents are just on the primary level,the interactive part in the virtual experiments are basically not involved,so as to this condition objectively has increased the difficulty of the experiment development.Firstly,this paper introduces the situation of the developing virtual reality technology and the application in physical experiment teaching.Secondly,It studies and analyzes the basic theory of education supporting the virtual experiment.Then it introduces the virtual reality technology,especially the realization technology based on Web3D: VRML,X3 D,XML,the animation script language and so on,specifically including three parts:model,display and interactive,the model section includes the geometric-based modeling and the image-based modeling;the display section is the rendering engine which mounted by the browser;the interactive section mainly consists of Java3 D,Cult3D,WebGL and the Three.js framework which based on the WebGL.Finally,taking the Ohm law of physics experiment as an example,according to the designed goal and principle,I explained the developing process through the virtual experiment based on the 3DS Max and Three.js in detail.Finally,this paper summarizes the innovation and shortcomings of the development on the experiment and planes the later works.Base on the final achievement,this paper rethinks the status of the virtual experiment in the experimental teaching while the information technology integrated into the subjects and puts forward the final suggestions on the teaching.
