As the computer is popularized in individual and society, it is using in a many of area. In particular, there are many materials to learn a science knowledge using multimedia through computer. Many of them are web-based learning materials, which are developed by Java or Flash. Since the technology of the representation, storage, computation and communication in computer make progress, the environment of education is also developed. Especially, the internet and VR technology will cause the education to change. A key feature of VR is real-time interactivity, in that the computer is able to detect student input and instantaneously modify the virtual world. It is reported that using the VR simulation in chemistry education can increase student engagement in class, promote understanding of basic chemical principles, and augment laboratory experience. In this study, application way of the virtual reality technology in chemistry education is examined.

452! Fig. 2. Spin Indicator: The frame around the spinning electron is an active interface element. One end of the frame is a golden arrow, which indicates the direction of the electron s spin. The electron s spin direction can be changed by grabbing the golden arrow and moving it to point in the opposite polar direction. Students are required to change the spin direction for the second electron placed in each orbital shell. (http://www.imprintit.com/creations/atom.html). Fig. 1. Symbols for the atomic particles: protons (3-D plus signs), neutrons (cubes) and electrons (minus signs)(above). Power Bar: puts required energy into the system enabling the addition of electrons. Settings on the power bar indicate the various orbital levels: S1, S2, P1(below). (http:// www.imprintit.com/creations/atom.html).
