Construction of Design System of Network Virtual Chemistry Laboratory based on Virtual Reality Technology

In order to improve the teaching efficiency of chemistry classroom, to enhance students' interest in chemistry, this paper constructs a novel design system of network virtual chemistry laboratory based on virtual reality technology. This system is based on virtual reality technology and Internet technology, which is different from the traditional chemistry laboratory. It can build a realistic chemistry laboratory for teachers and students and promote the communication between teachers and students. The research results show that the design system can not only improve the teaching quality and efficiency of chemistry classroom, but also promote the modernization and intelligent development of chemistry classroom.
