By Marvin Zelkowitz

Quantity fifty five covers a few fairly scorching issues. Linda Harasim writes approximately schooling and the net in "The digital collage: A country of the Art." She discusses the problems that might have to be addressed if on-line schooling is to stay as much as expectancies. Neville Holmes covers a similar topic in his bankruptcy "The internet, the internet, and the Children." He argues that the net is an evolutionary, instead of progressive, improvement and highlights the department among the wealthy and the bad inside and throughout countries. carrying on with the WWW topic, 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 element of discovering proper details in huge databases of their contribution. They speak about the algorithms, ideas, and methodologies for potent program of clinical information mining.Returning to the net subject matter, Ross Anderson, Frank Stajano, and Jong-Hyeon Lee deal with the problem of defense rules. Their survey of the main major defense coverage types within the literature indicates how protection may well suggest various things in numerous contexts.John Savage, Alan Selman, and Carl Smith take a step again from the purposes and tackle how theoretical computing device technological know-how has had an influence on sensible computing strategies. 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 desktop science-the chip-right to the functions and consumer interface with the net.

System administration tools: Functions that assist the system administrators in installing and maintaining Virtual-U, for example, creating and maintaining accounts, defining access privileges, and establishing courses on the system. Upload features: Tools that allow instructors and learners to send multimedia files from their local machines to the Virtual-U server. Learners electronically submit their assignments. and the instructors organize and comment on these submissions. 6 21 Results of the Virtual-U Field Trials The Virtual-U field trials are generating powerful data on instructional designs, impacts on instructor and learner workload, user satisfaction and practice, quality of learning, assessment issues, and student completion rates.

The costs presented reflect a teaching-oriented program, although the need for a virtual university to offer research orientation and graduate programming should be positively considered. The model proposed is based on offering three semesters a year (summer being a third semester) and allowing faculty to vary which of the three semesters they elect as vacation leave. 5. Defining the Virtual University: What It Is and Should Be Finally, this chapter examines what distinguishes existing virtual university model(s) according to the learning technologies and learning approaches employed.

Contrary to the general image of online instructors as young and male, we found that three-quarters of the professors adopting the Virtual-U were senior faculty and over one-third were female, and the majority taught in the social sciences, humanities, and health sectors, along with engineering and computing science. Their complaints generally related to workload and 22 LINDA HARASIM lack of technical support. These educators reported a powerful “rejuvenation” in their motivation and satisfaction with their accomplishments.
