ABSTRACT:
An electronic learning aid is provided with a display, a keyboard and circuits for posing a set of problems at the display and for comparing the operator's responses entered at the keyboard with correct solutions to the problems. A memory is provided for counting the total number of problems posed and the number of problems answered correctly. A circuit is provided for actuating the segments of the display with one of at least two different display presentations depending on the difference, if any, between the number of problems posed and the number answered correctly. The display presentations are fanciful actuations of the segments of the display of differing complexity of duration. The display presentations give the operator a "reward" for answering the set correctly. Also, particular display presentations may be initiated after each correct answer is entered. Further, a display presentation wherein the segments of the display are randomly actuated (at least in appearance to a casual observer) may be initiated for incorrect answers and/or a set of problems being answered with a low degree of correctness.
