A branched teaching machine that selects frames for presentation to the student in accordance with individualistic responses is connected to the remote control of a rotatable slide projector and causes the slide projector to move either forward or reverse in step with its search for the frame to be selected and presented. As the frame is presented, a slide in the slide projector may also be shown. As a primary feature of this invention, a printed paper record, attaChed to the rotatable tray, and giving a frame-by-frame resume of the teaching machine's branched programs, is electrically marked at all frames viewed by the student. Hence, a permanent, readily readable record is provided which can be used by a teacher to diagnose the path the student took in going through the teaching machine program.
