Quantity fifty five covers a few rather sizzling themes. Linda Harasim writes approximately schooling and the net in "The digital college: A nation of the Art." She discusses the problems that may have to be addressed if on-line schooling is to dwell as much as expectancies. Neville Holmes covers a similar topic in his bankruptcy "The internet, the net, and the Children." He argues that the internet is an evolutionary, instead of progressive, improvement and highlights the department among the wealthy and the negative inside of and throughout international locations. carrying on with the WWW subject matter, George Mihaila, Louqa Raschid, and Maria-Esther Vidal examine the issues of utilizing the internet and discovering the knowledge you want.Naren Ramakrishnan and Anath Grama speak about one other point of discovering suitable info in huge databases of their contribution. They speak about the algorithms, innovations, and methodologies for powerful software of medical facts mining.Returning to the internet subject matter, Ross Anderson, Frank Stajano, and Jong-Hyeon Lee deal with the difficulty of defense regulations. Their survey of the main major protection coverage types within the literature exhibits how safety may well suggest various things in numerous contexts.John Savage, Alan Selman, and Carl Smith take a step again from the functions and deal with how theoretical laptop technology has had an effect on functional computing ideas. ultimately, Yuan Taur takes a step even additional again and discusses the improvement of the pc chip.Thus, quantity fifty five takes us from the very basics of machine science-the chip-right to the purposes and consumer interface with the net.

Our turning out to be dependence on more and more complicated machine and software program structures necessitates the advance of formalisms, innovations, and instruments for assessing practical homes of those structures. One such strategy that has emerged within the final 20 years is version checking, which systematically (and instantly) exams no matter if a version of a given approach satisfies a wanted estate akin to impasse freedom, invariants, or request-response homes.

The definition employed excludes approaches that emulate traditional lecture halls by using synchronous technologies (videoconferencing, real-time chat rooms) and/or traditional distance education and individualized machine-based approaches such as computer-based training (individualized self-paced learning), nor does it consider models that use the Web primarily for publishing instructional or student materials with perhaps some e-mail connection between faculty and student. In this chapter, we consider a virtual university to be one that encourages the acculturation of students into the discourse of the discipline through interaction among peers and the professor.
4 Spatial Metaphor Until the invention of the Web, online learning environments were completely text based. 2 environments as they d o when reading prose. With multimedia, it became possible to provide explicit orientation cues, both for navigating around the virtual environment and for setting social norms about the appropriate behavior expected in each virtual space. In Virtual-U’s spatial metaphor. users navigate using images of university buildings, offices, and study areas (see Fig. 3 ) . While the key spaces are instructional, the Virtual-U environment also includes spaces for administrative activities, a library, social exchange (the virtual cafe).
1 Pedagogic and Administrative Models for a Virtual Un iversity A synthesis of emergent models for virtual universities includes the following: 0 0 0 Prestigious virtual university: Group/semester model, Prestigious traditional and virtual university combo, Professional virtual university: Group/cohort model, Best of breed virtual university (networked), and Niche virtual university. Before looking at these models, we should briefly compare them to the traditional university. Virtual and physical universities have unique attributes that determine major aspects of instructional design and delivery.
