However, this approach may inadvertently facilitate literacy gatekeeping and limit…

This study examined the effects of an intervention that integrated peer-mediated instruction (PMI) with augmentative and alternative communication (AAC) using speech-generating devices (SGDs). Nine trained peer tutors without disabilities taught science concepts and modeled use of SGDs following a script to three elementary school students with…

Children with Down syndrome (DS) are at higher risk for both delayed expressive language and poor speech intelligibility. The current study utilized the quantitative automated language environment analysis (LENA) to depict mother and child vocalizations and conversational patterns in the home of 43 children with DS, chronologically aged 24-64…

In this single-case design study, we tested the efficacy of peer…
