An interactive audio-visual teaching apparatus includes a video tape player, a video monitor, a student keyboard, a printer, and a programmed teaching controller, which can include a microprocessor. Teaching programs recorded on video tape include a plurality of lesson segments. A program control information code group is contained within the audio track of the tape in advance of the first program and indicates the position of the top of each program and the end of the last program. Segment control information code groups, recorded in the audio track respectively at the onset of each program, contain segment location data, correct answer data, branch instruction data, and the like for the segments of the respective program. A temporary memory, e.g., a RAM, is provided with the program and segment data, and a permanent memory, e.g., a ROM, contains universal software which is used with any previously prepared teaching-program tapes. The teaching controller provides mode control signals to the video tape player, as governed by the contents of the control information code groups in dependence on control pulses picked up from the control track of the tape. |
