Introduction
Over the past decade, there has been a sustained increase in and a need
for courses taught at a distance. Shotsberger (2000) reported that though it
took radio 38 years to reach 50 million users and TV took 30 years, the World
Wide Web hit that usage mark in a mere 4 years. The U.S. Department of Education reported in 1998 that
75% of 12–17-year-olds in the United States were online. The National
Center for Education Statistics (NCES) also reported that an estimated 25,730
courses were offered through distance education. Of these courses, 45% were
offered by public 4-year colleges and universities, private 4-year institutions
offered 16%, and 2-year colleges offered the remaining 39%. These institutions
offered approximately 700 degrees and 170 certificates that could be completed
by taking distance education courses exclusively (NCES, 1998). That was
determined in academic year 994–1995, and represented 33% of higher educational
institutions and over 750,000 students. Palloff and Pratt (2001) reported a
December 1999 NCES study that indicated ‘‘between the Fall of 1995 and 1997–98
the percentage of all higher education institutions offering distance education
courses increased by about one-third and that the number of course offerings
and enrollments in distance education courses doubled’’ (p. 4). Not only are
higher education institutions expanding their use of distance education
geometrically, but business and industry have also entered the distance
education field. Distance education courses and programs can now be found in
all of the 50 states and U.S. territories (Barker & Dickson, 1996). Miller
(1997) wrote that a 1995 survey in the United States showed that 62% of
middle-aged workers employ computers in their work, and in an additional survey,
46% of the people interviewed listed the computer as essential technology.
Computers and online distance education appear to
offer unrealized possibilities for lifelong learning in a country where
corporations are investing more than $80 billion each year on education and
training (Miller, 1997).
