Teaching Children with Autism Spectrum Disorder to Answer Questions Using an iPad-Based Speech-Generating Device.

Abstract

This study investigated whether a systematic instruction package was effective in child acquisition of question answering using an iPad-based speech generating device (SGD). The study was conducted with two children with autism using a multiple probe across behaviors design. Results demonstrated that the systematic instruction package consisting of graduated guidance, discrete trial teaching, time delay, and reinforcement resulted in acquisition of answering all questions. Follow-up data were collected one, three, and five weeks after instruction ended. For all participants, skills maintained during follow-up and generalized to novel settings and skills. Social validity data were also collected and indicated that teachers without experience using SGDs found them to be effective and feasible for teaching communication skills.
