Distance learning provides training to remote locations.
Distance learning has been available for many years and can be
categorized into public education (grades K–12), university
and colleges, professional (industry), government training, and
military training segments. In the early years, distance learning
was provided through the use of books and other printed materials
and was commonly referred to as correspondence courses.
Distance learning has evolved through the use of broadcast
media (e.g., televisions) and moved on to individual or small
group training through the availability of video-based training
(VBT) or computer-based training (CBT). These systems
evolved into interactive distance learning (IDL).
Distance learning relies on communication systems (e.g.,
phone lines or mail) to connect students and teacher as an
alternative to classroom training. Electronic learning
(eLearning) is a form of distance learning that is becoming a
viable option to traditional teaching methods and is poised for
major growth over the next several years.
Through the ability of broadband video and interactive
graphic technologies, students are exposed to far greater education
stimulus than in the traditional learning environment.
Integrated sound, motion, images, and text all serve to create a
rich new learning atmosphere and substantially increase student
involvement in the learning process.
The rapidly changing global economy is forcing industry
professionals to continually update their skill sets. Adults may
change their occupations several times in a lifetime as technologies
and skill sets become outdated. This requires continual
learning for adults. Adults between the age of 35 and 45 are
the fastest growing group of college learners.* To advance or
consolidate their careers, over 5 million adults complete some
form of distance learning each year.† This is one of the primary
reasons why online learning is booming, especially among
working adults with children. Distance learning via broadband
connectivity allows adults to attend classes in the comfort of
their living room or study, at their convenience.
Many online universities, including training and professional
specialty course programs, are catering to the rising
demand of industry to deliver skill-development courses to the
desktop at remote locations. These schools offer Web-based
professional certificates as well as associate and bachelor’s
degrees that are built around a solid core of business and computer
classes. Companies rely on these certificates to ensure
employees are qualified for their new jobs.
In 1999, most online classes did not require that students
have the latest high-powered computer. However, they did
require Internet access (via low-speed analog modem). These
distance learning courses were provided using low-resolution
graphics or slow-scan Web video. As broadband services
become more available and cost effective, it is predicted that
distance learning courses will evolve to use high-resolution
services such as high-resolution video conferencing.‡ Online
distance learning courses can be accredited by regional accrediting
agencies or via the Distance Education and Training
Council.
