Categories and Variables in Special Education

Abstract

This paper advocates an educationally focused definition of problems and procedures in educating handicapped children, with particular emphasis on the aptitude by treatment interaction model as a useful guide for both instructional and research activities. Specialized instructional systems based on decision variables are proposed as an alternative to simple categorization and placement of children based on source variables. A brief review of aptitude by treatment interaction research with handicapped children is followed by implications for the organization of schooling, diagnostic and instructional procedures, and preparation of teachers.
