Establishing evidence- and research-based practices relies upon research synthesis of individual studies in reviews and meta analyses. Further summarizing scientific evidence about a specific topic by synthesizing reviews is an area of need to determine practices that have a strong evidence base and to identify areas of methodological weakness and…

This review investigated virtual reality and augmented reality (VR/AR) communication interventions for children, adolescents, and adults with communication disability and neurodevelopmental disorders, as well the feasibility of these technologies. A search of five scientific databases yielded 5385 potentially relevant records of which 69 met…

People interact with individuals who use Augmentative and Alternative Communication (AAC) based on personal attitudes and perceived communicative competence. The purpose of this study is to investigate how different means of communication, such as an iPad-based Speech Generating Device (SGD), a communication board, and natural speech influence the…

Children with intellectual disabilities experience well-documented challenges in the development of problem-solving, particularly related to mathematical word-problem solving. Such challenges are related to both linguistic and conceptual skills. While interventions to assist children in developing conceptual skills are well reported, linguistic…

Enabling functional communication is critical for accessibility in school and society for all pupils. This systematic review analyzed the results of educational studies on developing communication skills for learners ([less than or equal to]21 years) with autism spectrum disorder and comorbid intellectual disability. Systematic database searches…

This community-partnered participatory study explores the outcomes of adult alternative and augmentative communication (AAC) users who qualified for special education under autism and/or intellectual disability. This multiple case study examines outcomes, the transition to adulthood, K-12 and special education experience, and the diagnosis and AAC…

Meaningfully synthesizing single case experimental data from intervention studies comprised of individuals with low incidence conditions and generating effect size estimates remains challenging. Seven effect size metrics were compared for single case design (SCD) data focused on teaching speech generating device use to individuals with…

Although functional communication training (FCT) is an effective intervention for increasing appropriate forms of communicative behaviors and decreasing inappropriate forms of communication (i.e., challenging behavior) in students with disabilities, its effectiveness might depend to some extent on the expertise of the interventionist. The purpose…

What are today's best methods for teaching literacy skills to students with complex support needs--including autism, intellectual disability, and multiple disabilities? This comprehensive guidebook has up-to-date, evidence-based answers for pre- and in-service educators. Developed by Copeland and Keefe, the experts behind the landmark book…

A phonics-based reading curriculum in which students used an iPad to respond was created for students with developmental disabilities not able to verbally participate in traditional phonics instruction due to their use of augmentative and assistive communication. Time delay and a system of least prompts used in conjunction with text-to-speech…
