The Research On Design And Realization Of Virtual Experiment Of University Physics Based On VRML

While in the process of traditional learning, the contrition between the theory accumulation and improvement of practical skills is becoming more and more outstanding than ever. However, the fast development of multimedia and network technology is bringing the new opportunity for education and new virtual force, and then virtual experiment is appeared.Virtual experiment is an operating environment based on its own hardware and software, which can supplement or replace partly, or evenly wholly, the operating steps for traditional experiment, with the help of graphics, simulation and virtual reality create via computer. Under the great trend of this research, the thesis, on the basis of analyzing on present of situation about vital experiment, make profound exploration over virtual experiment based on VRML, and design the virtual experiment of University Physics.The first part of thesis explains that the author organizes current research situation home and abroad by searching database and websites, compares different current development technologies of virtual experiment, and relate to the characteristic of university physics experiments, and finally decides to adopt technology of VRML; secondly analyses theoretical foundation of virtual experiment design and application form three aspects of the meaning of theory(such as Blended Learning, Inquiry-Based Learning, Scenarios of learning and Similar theory), the characteristic and supporting to virtual experiments; thirdly details VRML of function, working principle, browser and editor as well as some important concepts; fourthly research and explain VRML modeling technology, interactive technology and optimization strategy; finally analyses university physics experiments, and integrate with VRML technology to design virtual experiment of the collision, climbing cone and electromagnetic induction experiment.With the result of our research, it's easy to find a effective approach to improve the experiment teaching, enhance experiment performance, especial for those that there are more students and less experimental equipment and is not easy to achieve in the real condition, and it can also hold good meaning on the process to accelerate the networking and modernizing of the experiment teaching.
