Design and development of virtual experiment based on WEB3D

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 experiments, with the help of graphics, simulation and virtual reality created via computer. This paper analyzes problems in experiment teaching of Modern Educational Technology. The technical line of development of virtual experiments which develop via VRML and JAVA was proposed. And instructional media virtual experiment shows as the case. At last, we simply discuss the application of virtual experiment in teaching.
