With the rapid development of Web-based learning, a new set of learning - vironments including virtual classrooms, virtual laboratories and virtual u- versities are being developed.

On the learning side, the cyber mode of learning is very di?erent from tra- tional classroom-based learning. On the management side, the establishment of a cyber university imposes very di?erent requirements for the set up.
