Naturalistic observation procedures examined the use of time by 230 elementary students with disabilities in four special education placements--regular class, resource room, special class, and special school.

In response to criticism (EC 600 437), H. L. Rich and S. M. Ross defend their research published in April 1989. Naturalistic observation techniques used are discussed, conclusions regarding the regular education initiative supported, and findings concerning drawbacks of resource rooms reiterated and clarified.
