An audiovisual display system utilizes the video recorded instruction material and a television at the student location. Video information depicts a sequence of events leading to a choice of alternative actions followed by an indication of the possible alternatives. The system allows the user to select his choice of alternatives by tuning his television monitor to the station corresponding to that alternative. The likely outcome of the user's selection is depicted by video information broadcast on the various channels. The programs on each channel are timed to coincide with the master instruction cycle which may be broadcast on one or more channels.
