The present study evaluated the effects of online training on educators' knowledge and use of system of least prompts (SLP) to support the communication of individuals with autism who use augmentative and alternative communication (AAC). A pre/posttest group design with switching replications was utilized. Three dependent variables: (a) knowledge…

The adoption of methods and strategies validated through rigorous, experimentally oriented research is a core professional value of special education. We conducted a systematic review and meta-analysis examining the experimental literature on Technology-Aided Instruction and Intervention (TAII) using research identified as part of the National…

Refutation texts have been shown to be effective at promoting knowledge revision. It has been suggested that refutation texts are most effective when the misconception and the correct information are co-activated and integrated with causal networks that support the correct information. We explored two augmentations to a refutation text that might…

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…

Purpose: Many classroom educational assistants (EAs) have a significant amount of responsibility in carrying out educational plans for children who use augmentative and alternative communication (AAC), but they receive little instruction on how to do so (Kent-Walsh & Light, 2003). This study investigates the impact of using a communication partner…

Evidence-based practices (EBPs) are the basis on which teachers and other service providers are required to design educational programs for learners with autism spectrum disorders (ASD). As part of their work with the National Professional Development Center (NPDC) on ASD, researchers developed a process for reviewing the research literature and…

A study investigated whether the use of assistive technology would assist in the ability to identify symbols by three girls (ages 8-10) with Rett syndrome. Individualized multimedia programs resulted in a steady learning curve across symbol sets and a partial retention of knowledge throughout maintenance probes. (Contains references.) (CR)

Cognitive disability entails a substantial limitation in one's capacity to think, including conceptualizing, planning, and sequencing thoughts and actions, remembering, interpreting subtle social cues, and understanding numbers and symbols. Cognitive disabilities include intellectual disabilities and can also stem from brain injury, Alzheimer's…

A study evaluated the use of computer-based video anchors to increase photograph recognition by two students with severe intellectual disabilities. A substantial increase was made in the number of photographs correctly selected with the computer program with results generalizing to selection of photographs on each participant's augmentative…

This article discusses the assistive technology training needs of families and provides an overview of the instructional CD-ROM, "Families, Cultures, and AAC". This CD-ROM is designed to provide information about assistive technology, especially augmentative and alternative communication, to both professionals and families through an engaging…

Thirty children (age 2) were assigned to three system approaches: vocabulary in a grid format organized taxonomically; vocabulary in a grid format organized schematically; and vocabulary in an integrated scene organized schematically. Children performed poorly in all conditions but were able to locate more items in the schematic scene condition.…

In the study reported on here, the authors used computer-based video instruction (CBVI) to teach 3 high school students with moderate or severe intellectual disabilities how to order in fast-food restaurants by using an augmentative, alternative communication device. The study employed a multiple probe design to institute CBVI as the only…
