Education by TV
The potential for education by TV is unlimited. Advantages of using television for training are:
The world's best expert(s) can be secured to talk about the subject.
The expert's presentation can be rehearsed until perfect and then taped, eliminating human error.
The expert is always available on the tape—permanently, 24 hours a day. The tape never gets tired or makes mistakes.
Many copies of the program can be made.
The program can be shot on location anywhere in the world if the budget permits. The world becomes the classroom.
A taped program can be reused many times.
Films, slides, graphics and outside videotaped material can be integrated into the program, providing a flexibility not possible in the live classroom situation.
The program can be edited and time, space and distance manipulated to create the best effect.
The program can be made available on easy-to-use standardized videocassette formats which can be displayed on ordinary TV sets.
Videocassettes can be played for large groups through a video projector or played privately by one person on a small portable TV set.
The program can he repeated many times, stopped or advanced forward for the individual student's needs.
The overall cost of videocassette learning tapes is usually very cost-efficient, especially if produced on a large scale.
NOTE: There are many kinds of learning experiences that are NOT well suited to videotape presentations. It may be less expensive, simpler and more effective to use audiotape recordings, slide or filmstrip presentations or good printed materials to express a concept through media.
