Abstract: An electronic learning aid for interactive operation with an operator with capabilities for the synthesis of a tone or sequence of tones. The tone, in the alternative, is used to either prompt the operator to respond in like fashion or is in response to the operator's input of a tone or sequence of tones. In this fashion the learning aid selects a tune to be synthesized and communicates this tonal sequence to the operator who responds by attempting to mimic the sequence. An alternate operation of the learning aid is for the operator to audibly input a tone sequence and for the electronic learning aid to attempt to mimic the sequence of tones.

Abstract: An electronic learning aid in which the student supplies a problem to which the learning aid supplies a response. The response of the learning aid is sometimes correct and at other times incorrect, thus requiring the operator/student to respond as an educator of the learning aid. This educating of the learning aid by the student requires the ability to recognize the correct answer. Preferably, if the student recognizes the correct response, praise is given; otherwise, either the problem is explained to the student or the learning aid ventures another guess. This "educating" of the learning aid through the posing of problems from the operator allows the student to proceed at his own pace and yet tries the limits of his knowledge.
