The purpose of this study was to investigate the effect of an intervention package that included constant time delay (CTD) and sentence frames on correct word selection for sentences constructed using technology-aided instruction (TAI) during and following a story-based lesson (SBL) for participants ages 6-8 who have intellectual disability, developmental delays, and autism (IDD). A multiple probe across participants design was used to evaluate the efficacy of the intervention. Probes were conducted during baseline, intervention, generalization, and maintenance phases to determine the effectiveness of the intervention on correct word selection for sentence construction. Results indicate a functional relation between the intervention package on correct word selection for sentence construction during a shared story. Additionally, the Percent of Nonoverlapping Data (PND) indicate overall strong effects. Finally, students were able to demonstrate both generalization and maintenance of skills.
