Abstract
An educational learning aid which obtains its procedural data via bar code or other indicia imprinted on the edge of detachable work book sheets. The aid holds the detachable sheet over a touch sensitive array of switches so that touching or marking of the sheet is sensed by the underlying switches in the aid. The correct content of the answers is communicated to the aid by a bar code or machine readable section either on a work sheet or on a second sheet. In this fashion the operator responds to printed material on the sheet and is verbally reinforced by the learning aid for correct answers. Preferably a running tally of the operator's correct responses is kept and he is informed at the end of the exercise of his score. This score is optionally printed upon the paper upon completion of the exercise.
