Abstract: A system and method of communication based on the Reverse Multiple-Choice Method of teaching and testing is disclosed where at least one communicant is a machine. The method is applicable for training a machine for knowledge engineering and artificial intelligence oriented applications, as well as for a trained machine to assist a human being engaged in the activity of teaching or testing.

Abstract: The present invention comprises methods of developing and implementing educational products or materials, including testing products or materials, by utilizing multiple-choice questions. Starting with a given set of facts to be presumed in a question, the method may require one to examine each answer choice, and inquire how a set of facts to be presumed could be modified to make that answer choice the “correct” or “best” answer choice. If a given answer choice is already correct, no modification is needed. If a given answer choice is not correct, various modifications may be employed, including changing some of the words or phrases, or other symbols or objects within the set of facts to be presumed.
