A computer-based system--the Educational Assembly System for Student Executed Educational Design (EASSEED)--is used to generate individualized curricula for students with varying needs and goals. It combines advances in management and computer technology to define the processes of curriculum development and thus moves toward an explicit operational description of a normative theory of curriculum development. EASSEED functions by directing students to instructional materials, the completion of which fulfills the goals set by the student. The system is organized into content and structure modules; the former direct the student to materials related to achieveable goals while the latter decompose broad goals into progressively more manageable sub-goals until a level is reached at which a suitable instructional material is available. Goals are processed by the system's semantic net; all terms in the system are located in the net and pointers lead the student to higher order, equivalent, and implied terms. The system provides the basis of computer constructed education, for it can be used as a course prerequisite, supplement, or substitute, for course design and subject area definition, as a resource evaluator, and for generalized program support.
