Abstract


Modern education theory emphasizes that learning process is the interaction process between human and environment and knowledge should be based on the presentation of real learning conditions. Virtual Reality technology is a totally new technology that succeeds multimedia and network technology and it plays an active and necessary roll in providing an emulated learning environment for learners.Virtual Reality technology is classified into four types according to immersion degree, and desktop virtual reality technology has its advantages for its low develop cost, widely used application platform and obvious effect. Desktop virtual reality technology mainly means Web3D technology and it includes two types: one is synchronous model creation and dynamic display technology based on geometry model, the other is synchronous model creation and dynamic display technology based on image. VRML, Cult3D and QTVR of Web3D technology is being paid more and more attention by education field for its powerful function, easy application, prominent effect and plentiful resource and they provide environment for popularizing virtual reality technology in subject teaching.The first half of the article begins with E-Learning. It explains the active effect of importing virtual reality technology into subjectteaching. Then, several mainstream learning theories (including constructivism learning theory and circumstances cognition learning theory) are analyzed. And its basic perspective and typical teaching methods are analyzed and it serves as the theoretic foundation. Based on introducing virtual reality technology, the article compared several mainstream Web3D technologies, analyzed technology feature, develop system and teaching application case, etc of QTVR, VRML and Cult3D and put forward the basic train of thought of popularizing them in subject teaching.The second half of the article illustrated Modern Teaching Media Three-dimension Simulation Virtual Teaching System developed by myself, from the view of technology, the author introduced applying VRML, Cult3D and QTVR to develop teaching resources in subject teaching and the concrete process and realizing means to create learning circumstances in detail. And some perspectives of applying Web3D to subject teaching are also presented.
