In 2 years of activity the Study of Curriculums for Occupational Preparation and Education (SCOPE) has moved in the direction of systematic, interdisciplinary, self-improving curriculum development. A major product of this phase of the study is a three-dimensional (domain-process-object) taxonomy covering the perceptual, cognitive, affective, and psychomotor domains. Also, conferences sponsored by SCOPE for 15 curriculum development laboratory directors resulted in the organization of the Vocational Instructional Materials group for the purposes of promoting interest in instructional materials. A third area of concern has been experimental studies of homogeneous versus heterogeneous ability grouping in secondary schools. In examining 18 such studies, SCOPE found that little support existed for either. SCOPE also attempted to design a curriculum development model that included task analysis, behavioral objectives, insructional activities, and evaluative procedures. SCOPE is based on a philosophy of a student-centered curriculum which emphasizes individualized, hands-on education. A related document is available as ED 027 438. (JS)
