Education or training courses are delivered to remote locations via synchronous or asynchronous means of
instruction, including written correspondence, text, graphics, audio

and videoconferencing, interactive TV, and facsimile. Distance learning does not preclude
the use of the traditional classroom.

technology is used to make new approaches to the teaching and learning processes possible.
