Increasing opportunities for requesting in classrooms serving children with developmental disabilities.

Evaluated an intervention package for increasing requesting opportunities in special education classrooms. Five teachers, serving 26 children with moderate to severe disabilities, received in-service training, consultation, and feedback on the use of three strategies designed to create opportunities for requesting (i.e., missing item, interrupted chain, delayed assistance). Observations were conducted in a multiple-baseline across classrooms design to record the number and types of opportunities provided by each teacher. During baseline, few opportunities for requesting were observed. The number of opportunities for requesting and the number of correct student responses increased during intervention. Opportunities continued to be provided during generalization and follow-up sessions. The study demonstrated an effective strategy for helping teachers incorporate opportunities for functional communication into the natural environment.
