The Research And Design Of Middle School Virtual Chemistry Experiment Based On 3D And EON

Along with the rapid development of on—line education,the virtual experiment experienced from academic research to practical application. The research put forward the design method on the basis of the actuality of virtual chemistry experiment and the problem of tradition chemistry experiment,at the same time,do some work on the design and research.Virtual experiment is a kind of experiment mode that produce and develop relying on"virtual reality"technology. Presently,the form of VR mostly used in chemistry experiment teaching is desktop VR.The desktop VR mainly depend on VR software to be carried out with a little requirement toVR hardware which are too costly to be used in experiment teaching.There is some difference desktop VR and other more advanced forms of VR . But the traditional teaching chemistry experiment is a great innovation and improvement.This paper will be desktop VR and multimedia technology , network technology, presents a virtual chemistry experiments based on the platforms of EON Technology Architecture,and the conduct of research and design.After analyzing the theoretic basis,development clew,correlative technology in detail,The research introduce the development environment,and give a design example of virtual chemistry experiment instruction . In the part of summarization, Firstly,Virtual experiments in the development of the situation at home and abroad and the contents and characteristics of VR experiment. Secondly,In the part of the theory of chemistry experiment,Highlights outlined in the traditional teaching of chemistry experiment , Under the guidance of the theory of constructivism and analysis in the design of chemistry experiment and the lack of traditional chemistry experiment . And chemistry experiment to explore new forms of teaching.In the part of correlative technology about virtual experiment,the 3D technology and EON technology are introduced especially . In the last , in the platforms of EON Studio development tool environment,an experiment about copper sulfate reaction is designed.
