Abstract: The present invention provides an electronic testing device for use in responding to questions of quizzes periodically provided in an educational text book. The testing device itself comprises a rectangular housing either permanently or removably affixed to the back cover of the book, an input section for entering selected answers corresponding to the questions, a logic section for comparing the selected answers with correct answers programmed into memory and an output section for providing immediate and enjoyable audio-visual feedback to the user. In a first embodiment of the present invention, the device comprises a small and compact rectangular housing adapted for permanent affixation or removable attachment to a protruded edge of the back cover of a specific educational book. Alternatively, the device may form a small, portable unit that can be detached from the book for use with quizzes of a plurality of different text books.

Abstract: An electronic educational teaching apparatus is disclosed herein for use in learning key subjects such as geography, which has an information card presenting visual question and answer data and supported in a holder or stand which houses an electronic circuit for comparing user input answer data with memory stored correct answer data. In one form, the apparatus includes a microprocessor employed with an input keyboard for entering answer data and an output display to indicate answer results. Internal circuits compare the user input answer data with the stored correct answer data and with interconnecting circuits to sense right and wrong answers with alarm, display and score registering capability. The keyboard input is processed by the microprocessor, then coupled to LED displays via LED drivers. An audible device is connected to the microprocessor for providing audible indications of answer correctness. Power supply circuits, including D.C.

Abstract: An instructional device is disclosed herein having a booklet containing a series of sheets displaying questions, selectable answers and clues taking the form of pictorial, graphic and alpha/numeric characters. The selectable answers are displays of specific graphic forms and these graphic forms are repeated in seemingly random arrangement on an answer area of the sheet which includes an index mark. A separate decoder is provided having a case with open windows adapted to visually display underlying graphic forms from the answer area for visual comparison with selected graphic forms entered by the user into the decoder via movable members carrying graphic forms wherein the selected graphic forms on the movable members appear adjacent to windows with the correct answer association.

Abstract: Self-teaching apparatus is disclosed herein having a platform for supporting a card carrying printed indicia and a record disc. Information carried on the disc and the printed area is coordinated so as to be meaningful in practice. Record disc playback mechanism and an operating circuit is intercoupled with an electrical probe actuator so that the auditory instructions or information can be related to the printed indicia. In one form, a solid, pliable platform is employed with a membrane switch included in the circuit and, in another form, holes are placed through the platform for passing an electric tip on the probe for contact with a plate connected to the circuit. The card is provided with holes in the latter form and without holes in the former form.
