This study compares the effectiveness and efficiency of constant time delay (CTD) and simultaneous prompting (SP) to teach decoding and word reading to four students, 7 to 9 years of age, with intellectual disabilities (ID) in the mild to moderate range. An adapted alternating treatment design was implemented to assess the two methods. The results…

Children with Down syndrome (DS) using intensive computer-based phonics (GraphoGame, GG) were studied. The children's independence and improvement in phonological processing, letter knowledge, word decoding, and reading strategies were investigated. Seventeen children (5-16 years) with DS participated in a crossover design through 8 weeks (one…

Students with intellectual disabilities need more time and explicit instruction to develop word decoding. Most previous research on interventions among these students is performed in English. Therefore, the current study examined the impact of a word-decoding intervention in Swedish on individual students with intellectual disabilities. A…

This study examined the response of two students in the Southwestern United States with autism spectrum disorder and IQ in the intellectual disability range to a comprehensive, text-based reading intervention. The intervention, "Friends on the Block," includes multiple strands of literacy providing explicit instruction in phonics,…

The purpose of this article is to describe recommendations for providing evidence-based literacy instruction to students with intellectual and developmental disabilities (IDD), including students with comorbid autism spectrum disorder (autism). We identify six evidence-based practices, highlight key research that supports each practice, and then…

Purpose: Reading and writing are foundational skills that provide access to educational, vocational, and social experiences. However, while the gap widens between the literacy skills of individuals with intellectual disability (ID) and those with typical development as they grow into adolescence, little is known about meeting the comprehensive…

The importance of helping all children make meaningful progress in reading development is supported by legislative mandates and court rulings. The purpose of this research was to describe findings from a series of single-case design studies completed over three years to test the effects of a specific comprehensive literacy intervention, Friends on…

Purpose: Multiple factors impact reading acquisition in individuals with reading disability, including genetic disorders such as Williams syndrome (WS). Despite a relative strength in oral language, individuals with WS usually have an intellectual disability and tend to display deficits in areas associated with reading. There is substantial…

Success in school and future participation in college and workplace environments depend upon attaining proficiency in reading (National Governors Association Center for Best Practices [NGA], Council of Chief State School Officers, 2010). Proficient reading entails decoding printed words and comprehending their meaning (Hoover & Gough, 1990).…

The present article aimed to explore how the development of reading comprehension is affected when its cognitive basis is compromised. The simple view of reading was adopted as the theoretical framework. The study followed 76 children with mild intellectual disabilities (average IQ = 60.38, age 121 months) across a period of 3 years. The children…

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…
