Abstract: Apparatus and a method are disclosed for offering branch programming for instructional purposes. The apparatus comprises a tape player of the cassette variety, preferably having a tape index or counter. A prerecorded tape cassette carrying the program of instruction is also included. The tape has a plurality of segments of primary material recorded over corresponding spans of tape in a forward direction on a first track. A plurality of segments of supplemental material related to the primary material are recorded in a reversed direction on a second track. The primary material segments each terminate in segment-defining indicia aligned with the initiation of the corresponding secondary material segment. In use, the listener plays a primary material information segment, and then stops the tape player. If further development of the subject is desired, the listener removes the cassette, and flips it over or reverses its orientation. He then reinstalls it in and upon the tape player.
