The Development And Application Of A Virtual Experiment System Based On Web

It's that the application on Virtual Experiment in the field of education, what becomes more and more popular and valued. Under the quickly development of Virtual Reality now, Virtual Experiment is not only a very significant element in E_Learning (modern distance education learning), but also a solution about those problems existed in Exp.Teaching. Virtual Experiment gets good foreground especially in those Primary&Secondary Schools, which are weak in experimental installation and investment. However, design, development and application of Virtual Experiment become hotspot in colleges, which are under good conditions. The paper develops practice and research, centering on development and application of Virtual Experiment System based on Web, which getting a Media experiment—the use of Video Presenter as an example. It comes from "Modern Educational Technology", a national superior course.After literature being combed though and summarized ,concept,history,peculiarities and sorts of Virtual Experiment are expounded systematically .What's more, the current situation domestic and overseas of Virtual Experiment is presented besides the trend.Theoretical principles about the application of Virtual Experiment in the field of education are summed up. It could be known from Dell and his "Cone of Experience", Experience could be gotten from using Virtual Experiment Systems; further more, it could be transferred into reality if experience comes from a proper Virtual Experiment System. Combining the transfer with peculiarities of Virtual Experiment, it could help learners carry autonomic learning. And new foreground about Virtual Experiment instruction is brought from Blended Learning.After principles of Virtual Experiment's development, VRML&JavaScript are selected; the path of Virtual Experiment's development is established. Then the development is described in details as the example selected, including modeling,parts of functions and etc.Based on the experience of the original, a case for the application of the Virtual Experiment is presented at last, besides instructional evaluations about it.
