The Structural Strategy Diagnostic Profile Project developed the elaboration model of instruction as a superior alternative to standard instructional sequencing based on hierarchical task analysis. The theory construction phase, the first of two phases, identified the instructional variables, postulated cause-effect relationships, and proposed optimal configurations of instructional conditions and methods through the construction of a model (or theory); the second phase included the application of the instructional model to the design of a course in a subject-matter area and the development of procedures for implementing this model in the design of new instruction. Four major products of the project are described: (1) an instructional model for sequencing, synthesizing, and summarizing related parts of a subject matter; (2) a taxonomy of the variables that are included in the model; (3) a set of procedures for designing instruction, based on the instructional model; and (4) a 'blueprint' illustrating the application of those procedures for the redesign of the Navy's Basic Electricity and Electronics course.
