Multimedia workstations were used for video to the desktop, desktop video teleconferencing, and access to multimedia servers via Mosaic and the World Wide Web. The tests that were conducted, and the results and trends, are covered in detail in this paper.

.3 4 Five widely dispersed graduate-level engineering schools (Oregon State University, Oregon Graduate Institute, University of Oregon, Portland State University, and Oregon Health Sciences University) and several state office buildings were linked together via a network of ATM switches and associated OC3c and DS3 lines in several major cities In western Oregon.

Direct ATM connectivity was extended to workstations and hosts to allow them to communicate directly over ATM using native IP per RFC 15777 as well as to distributed ATM hubs supporting lOBASET and 100 Mbps Ethernet for devices using LAN emulation.8 Based on this high level of sophistication, one moot make the mistaken assumption that LANs are therefore too sophisticated for school districts to deploy. However, we found that the trial school district and library locations had numerous LANs already in place.

These workstations provided the ability to receive audio/video broadcasts at the desktop, to engage in desktop video teleconferencing, and to access multimedia servers. Initial testing was primarily with high-end SG!

A 3-week-old baby at the patty was given the distinction of being the "youngest person to ever do an Internet broadcast." Desktop Video Teleconferencing Closely related to the delivery of video to the desktop is the use of desktop workstations for video teleconferencing. Desktop video teleconferencing emerged as a strong trend in bow the Oregon and the Boulder trials.

It is precisely this kind of new, dynamic interaction between experts, information resources, and students at venous levels that precipitates the kind of quantum leap the experience of learning can undergo. Finally, a number of demonstrations were held In conjunction with efforts associated wad the Council of Great City Schools, a nonprofit organization representing 50 of the nation's largest urban public school systems.

Along He same lines but on a larger geographic scale, He Council of Great City Schools is proposing an "Urban Leanung Network" to link urban high schools in 14 states to deliver usefi~t information and practical educational services to teachers and students in the real-world environments of urban community high schools. The proposed list of services and applications to be provided should sound familiar at this point: video on demand, interactive multimedia courses, distance instruction or teleconferencing, electronic field trips, and filthy equipped smart classrooms.

, means Hat K-12 and learning communities can begin accelerated access to the information highway today, migrating to over exclusively fiber networks over time. Although DS3 and over higher speed network capabilities are open desirable, it is currently neither feasible nor financially possible to extend these capabilities universally to all schools.
