With the rapid development of Web-based learning, a new set of learning environments including virtual classrooms, virtual laboratories and virtual universities are being developed. These new learning environments, however, also introduce new problems that need to be addressed. On the technical side, there is a need for the deployment of effective technologies on Web-based education. On the learning side, the cyber mode of learning is very different from traditional classroom-based learning. On the management side, the establishment of a cyber university imposes very different requirements for the set up. The aim of this session is to invite researchers from various fields to present and discuss their ideas on Web-based learning technologies
