Research And Implementation Of Virtual Laboratory Platform

Along with the constant popularization practices of computer, multimedia and telecommunication in the field of education, virtual laboratory has been widely applied. Virtual laboratory can not only be a useful tool to support the research work of universities, but also plays a significant role in experimental teaching. However, deficiencies still exist in the progress of designing and developing this new teaching method. The purpose of this thesis was to make intensive study on key technologies in designing virtual laboratory platform, demonstrate a feasible proposal for virtual laboratory platform and implement a virtual laboratory on the platform.This thesis firstly introduced the background and research status both domestic and abroad. Following in this thesis, web services, single sign-on, technologies in implementing virtual experiments were referred. The third chapter analyzed the functional requirement of virtual laboratories, on top of that, common services and CAS (central authentication service) were explicitly designed according to the infrastructure of virtual laboratory platform, primary interfaces and database design were included as well. Related feature implementations were involved in the forth part, concerning details of utilizing web services and Yale CAS to configure the virtual laboratory platform. In order to validate the feasibility of the proposed platform design for virtual laboratory, a component of computer hardware based on fundamental of university computer was designed, which was mainly implemented by invoking common services, deploying CAS client, and fixing a well designed virtual experiment.
