A computing device is adapted to construct a user-memory data structure for a user based on interactions with the user. The user-memory data structure may comprise a plurality of memory representations for concepts and items important for gaining proficiency in a subject matter. The memory representations are dynamic, and characterize how well each of the concepts and items are retained as a function of time by the user. The computing device uses the user-memory data structure to guide operation of the computing device.

A method for controllable toggling viewing of written materials with adjuvant or explanatory notation material as a teaching or memorization tool. The method comprises the steps of imprinting adjuvant or explanatory notation materials adjacent to or in close conjunction with a visible text or notation, as a non visible or an invisible imprint. The non visible invisible adjuvant or explanatory notation material is made to become temporarily visible or viewable with a heat source or a viewing device for a controlled desired period of time by using the visible adjuvant or explanatory notation to perform a reading or writing function. Removing the viewing device or reducing heat renders the adjuvant or explanatory notation non visible or invisible.

A learning aid for learning a primary text along with a related secondary text, such as a translation of the primary text. The secondary text is interlineated with the primary text. Highlighting and flagging specific portions of the text may be done by using color coding, symbols, and similar techniques known in the relevant art. Further, coordinated spacing is used to line up similar words, and gaps are inserted where the words of the primary text and secondary text do not correspond directly. Also disclosed is a method for learning a manuscript using this learning aid. Further disclosed is a learning aid for learning cantillation of a primary text by color coding the cantillation notations.
