Naturalistic observations of classrooms serving severely handicapped persons: establishing evaluative norms.

A naturalistic, observational analysis was conducted of 43 self-contained classrooms serving severely handicapped students. The primary focus of the observations was on levels of on-task student performance and student involvement in functional educational tasks. Results indicated that during designated instructional periods, slightly less than half of all student time was spent on-task. When students were on-task, almost two-thirds of their time involved nonfunctional instructional tasks. Results are discussed in terms of establishing norms for evaluating and improving educational services for the severely handicapped. Additionally, future research directions are noted, with a particular emphasis on investigating means of assisting educators in providing more useful teaching tasks for severely handicapped students.
