Distance education is possible and does occasionally occur without the support of pre-produced courses. A tutor, with whom the student is in non- contiguous contact, then guides the individual student's study of pre-agreed literature.
11.

"Teleconferencing is the bringing together by electronic means of three or more people in two or more locations to share a common discussion. It is generally understood to include the use of two-way and one-way video (both full motion and slow scan), electronic blackboards, facsimile, computer graphics, radio satellites, and telephones. The most essential portion of all effective teleconferencing is good quality audio". From Robertson, B. "Audio Teleconferencing: Low Cost Technology for External Studies Networking".
