Outline
  • Need
  • Definitions
  • History
  • Delivery models
  • Opportunities
  • Barriers
  • Internet and the World-Wide-Web
  • Economic and social issues
  • Case Studies

4
The need
  • Any time, any place
  • Convenience
  • Asynchronous access
  • Remote locations

5
Definitions -- 1
  • Distance learning -- student and teacher
    separated in place and/or time
  • Asynchronous learning -- educational material may
    be accessed at the students convenience
  • Distance education -- the delivery of a complete
    course or program at distance
  • Multimedia courseware -- course material
    containing a variety of media types, e.g., text,
    audio, graphics, video, animation

6
Definitions -- 2
  • Distance learner -- the student receiving
    educational material at distance
  • Distance teacher -- the person primarily
    responsible for developing and delivering the
    educational material
  • Mentor -- a person responsible for assisting the
    distance learner
  • Competency-based education -- assessment of
    knowledge learned versus the accumulation of
    credits

7
Definitions -- 3
  • Content provider -- the institution that owns
    the course
  • Course broker -- the institution that offers
    the course
  • Educational infrastructure provider -- the
    institution that provides the services to develop
    and/or delivery courses at distance

8
Historical perspective
  • Correspondence courses (1940s to present)
  • Remote classroom facilities (1960s to present)
  • Closed-circuit television networks (1960s to
    present)
  • Video tape delivery (1980s to present)
  • Satellite television (1980s to present)
  • Video conferencing (1990s)
  • Internet delivery (1990s)

9
The providers
  • Traditional universities
  • Not for profit institutions, e.g.
