geographically dispersed public network. This trial environment
offered an opportunity to explore existing biases about fiber optic
and high-speed networks, overcome the constraints of distance and
dispersed population centers, and bridge the ever widening
educational gap between technological "haves" and "have nots."
Education and lifelong learning are primary keys to societal
success on both a personal and a national level. As our
information-oriented society continues to move rapidly forward,
tremendous pressures are exerted on schools at every level of
learning. The rate of information acquisition in learning and
scientific inquiry is astounding, making it extremely difficult for
teachers and school districts to keep up. The problem is
particularly difficult for both rural and urban schools with
limited enrollments, diverse student populations, and constrained
budgets. Many students in these types of schools are being taught
advanced topics by minimally qualified teachers with outdated
textbooks. These students are placed at a decided disadvantage if
they advance to the college level and are forced to compete with
students coming from schools with advanced curricula based on more
current information. Worse yet, certain subjects may not even be
taught in some schools due to lack of resources or expertise.
The trial activities described in this paper support the premise
that these shortcomings can be addressed by means of a high-speed
network to integrate communications transport at a variety of
speeds and bandwidths and effectively partner university-level
experts with teachers and students in the K-12 system. Such a
network, both technological and human, can allow for a more
efficient delivery of information and curricular material at both
the university and K-12 levels.
Beginning in April 1994 and extending through March 1995, US
West engaged in a set of technical trials of asynchronous transfer
mode (ATM) technology in western Oregon and in Boulder, Colorado.
Partnering with several leading universities and a number of other
organizations, these trials explored issues surrounding the use of
advanced networking technologies in combination with existing
network services. Issues that were addressed included network
platforms and architectures, along with an understanding of the
types of applications that would use such an advanced mix of
networking technology. Many planners assumed that high-end niche
applications associated with such things as supercomputers would
predominate. However, we soon realized that trial participants were
placing a strong emphasis on the extension of advanced technologies
to secondary schools. Even as that trend began to emerge, some felt
that while extension of advanced technologies to secondary schools
might be technically feasible, economic and social factors would
make such applications unworkable.
Innovative work conducted separately by the University of Oregon
and the University of Colorado proved the skeptics wrong. Advanced
capabilities were in fact extended to a number of secondary schools
in both Oregon and Colorado with encouraging results. This paper
discusses the experiments that were performed, the trends observed,
and subsequent plans made for follow-on activities. Insights gained
are used to project a baseline of technologies that could be
deployed over the next 5 to 7 years. We believe that these results
should influence the deployment of advanced technology to secondary
classrooms and could serve as a model for effective future
cooperation between universities and K-12 schools.
Background
US West announced a multiphase ATM strategy in October 1993.1 Key elements of this strategy
included small, scalable ATM switches flexibly and economically
deployed in a distributed architecture, as was done in the western
Oregon and Boulder, Colorado, trials. The results were positive,
and US West subsequently announced availability of an ATM-based
Cell Relay Service offering in its 14-state region in January
1995.2
Experimentation in Oregon was conducted in conjunction with the
Oregon Joint Graduate Schools of Engineering as part of "Project
NERO" (Network for Education and Research in Oregon).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. In addition, connectivity was also extended to a
teacher training workshop at school district headquarters in
Springfield, Oregon. Experimentation in Boulder, Colorado,5 was conducted in conjunction with
