Abstract
Abstract A device for teaching a multiplicity of students the same subject matter or different subject matter on each of a plurality of machines, by presenting these in visual and audio form, asking pertinent test questions and receiving the answers on a sound track, such as a removable cassette tape, to enable the teacher to evaluate the progress of the student in the subjects being studied. A lesson selector element is utilized for each lesson to be taught. The lesson selector element automatically sets or resets the machine to the particular lesson to be taught. The lesson selector element thus teaches the lesson for a predetermined number of minutes, when the visual and audio portions are cut off, at which time a signal is given the student to answer or to recite answers to questions relative to the particular material taught, and to automatically stop and reject the lesson selector element, after the recorded material has been properly identified on the sound strip by indicia. The teacher may thus evaluate the answers in accordance with the subject matter exposed to the student.
