Sophisticated computer description based on interrelated object models are advanced stores of information to be collected and applied during various fields of activities. The authors of this paper studied some advancements in object models for the description of course related groups of objects. They discuss several issues from this area that are considered to be important for the future development of highly integrated course models in higher education. In this paper, an introduction to high level application of Internet technology for virtual computer based teaching and learning is given. Following this an integrated concept for virtual classroom is cited and evaluated. The main part of the paper discusses three issues, namely resources, possibilities for storage of results, and entities for flexible model description.
The rapid economical development as well as the economic globalization put forward new requests for the application-orientated talent cultivation. Zhejiang University of Science and technology deepen teaching reform o...
