Abstract
The need for access to educational material, courses, and programs anytime and
anywhere has led to the concept of distance learning or distance education. While the
delivery of education at distance is not new, recent advances in computer and
communications technologies have opened up new opportunities and created new
expectations for both recipients and providers. In particular, the internet and the WorldWide-Web promise to revolutionize the educational delivery system and to change the
concept of distance learning.
The paper begins with a definition and brief historical perspective of distance
learning as a means to set the stage for discussing what the future may hold. Various
models of distance delivery are described and discussed in terms of their advantages
and disadvantages. The economic and social aspects of distance learning are explored
in the context of potential benefits and risks. Also, the paper addresses opportunities
and pitfalls that distance learning offers for learners and for providers. Finally, the
paper offers a glimpse at the potential impact that the internet will have on the global
educational delivery system.
