An Instructional Support System for Occupational Education (ISSOE) was designed to support and facilitate instruction by systematizing those functions essential to occupational programs--reporting, monitoring, and evaluating. ISSOE operates on several levels simultaneously: individual student achievement can be reported, class progress can be monitored, and entire programs can be evaluated. ISSOE rests upon a performance-based modularized curriculum as basis for reporting the achievement of individual students. The ISSOE curriculum package is a compendium of objectives which lead to employability in the world of work. These objectives have been based on task analyses, and the judgments of experienced teachers and are employer-validated. They are written in behavioral terms to provide a criterion-referenced testing system. Phase I (1975-76) focused on the development and testing of a system of curriculum development for the ISSOE effort. Phase II (1976-77) provided for format revision in the model. Phase III (1977-78) resulted in the following: (1) transition of the system from Cornell to other higher education institutions in New York State; (2) development of a process of employer validation of ISSOE major objectives in regard to their relevance to competencies needed by entry level workers in related occupations; and (3) the designing and piloting of a prototype competency-based student reporting system for ISSOE, with the manual system to be tested during 1978-79.
