Patent number: 5997306Abstract: The present invention is directed to an instructional method based on the concept that as a student learns to perform a mental task consisting of a set of elements or steps, whether conceptual or concrete, the student develops a distinct mental connection or path for every element related to the primary mental task being learned. For example, as a student learns to type a particular key on a keyboard, (the primary mental task), the student develops a distinct mental impression for every typing key logically associated with the first key. In other words, a distinct connection or path is defined as a link between two or more elements, one key being a primary element, the other being a related key connected to the primary key by a logical mental step. The present method is also useful for learning a musical instrument, a foreign language, mathematics, test taking skills, and the like logical though processes.Type: GrantFiled: December 16, 1997Date of Patent: December 7, 1999Inventor: Joseph B.
