1. A method for interpreting a problem statement and providing goals for solving a problem in said problem statement comprising the steps of:

  • storing in electronic memory a plurality of goal statements, each indicating an educational purpose of a subject matter area;

    identifying in each goal statement at least one subgoal statement address and/or prerequisite goal statement address;

    forming in electronic memory a semantic network by storing a plurality of key words associated with each of said goal statement addresses;

    a goal statement address of each of said key words, a list of any synonyms for each of said key words, a list of any terms generic to each of said key words, and a list of any terms which are a species of said key words, each key word being given a specific address location, each of said key words, synonyms, generic and species terms being thereby interlinked to one another and to each goal statement associated therewith and being linked to a corresponding key word in memory and to its synonyms, generic and species terms;

    inputting a problem statement;

    determining key words of said input problem statement;

    comparing said key words with said stored key words; and

    searching goal statements having said key words therein wherein said determining the key word step includes the steps of determining if a connector term connects two or more key words in the problem statement; and

    searching said goal statements in accordance with said connector terms further comprising the steps of;

    applying constraints to said input problem statement to thereby limit the scope of goal statements listed; and

    wherein each of said goal statements includes a vector designating the constraint criteria for said goal statement wherein said constraints listed for each of said goal statements includes a designation of the level of complexity, the level of mastery of the subject matter required and the anticipated study time in order to master said subject matter to the degree indicated further comprising the steps of changing each connector to an "in the context of" function; and

    performing said search for goal statements containing said key words.
