ABSTRACT:
An electronic learning aid of the type having a keyboard, a display at which problems are posed, a circuit for posing problems at the display, and a circuit for comparing proposed answers entered at the keyboard with correct answers, is provided with a timing circuit for measuring elapsed time while a set of problems is being posed to an operator of the learning aid. The timing circuit is preferably arranged to actuate different segments of a timing character in the display when the timing circuit is performing its timing function. The timing circuit is also preferably arranged to actuate, at the conclusion of a set of problems, the display to provide an indication to the operator of the learning aid the total elapsed time taken in solving the set of problems.
