Computer-Assisted Instruction Via Video Telephone
A teaching system utilizing a video telephone as a terminal in which the video telephone is tied into a computer whereby information is fed into the video telephone and other information is returned to the computer. A video tape recorder, containing a central bank of pre-recorded reels of video tape, is connected to the central processing unit of the computer and the video telephone whereby pictorial representations as distinguished from the alpha-numerical representations will appear on the screen of the video telephone enabling interaction with the student. This central bank of pre-recorded reels of video tape is connected to a buffer unit so that selected tape reels can be transfer recorded into the buffer unit where it is played back to the student selecting such tape. In this manner, the pre-recorded reels of video tape in the central bank will be available almost simultaneously to a large number of students at different terminal units in the teaching system.
