There is a dearth of appropriate reading material for adults with intellectual or developmental disabilities (IDDs). Often, a book's content is relevant to younger audiences, or its reading level is inaccessible. In this pilot study, we determined which factors facilitate reading accuracy and comprehension for this population. We wrote and tested…

This multiple baseline across-participants single case desgin study examined the effect of small group, phonological awareness intervention on the phonological awareness skills of three school-age children with Down syndrome. Each child with Down syndrome was paired with a typical peer to participate in small group intervention, three sessions per…

The purpose of this study was to analyze published decoding tests, at the item level, to determine what decoding skills and discrete letter-patterns are assessed, and identify potential instructional implications of these measures. Twenty published word list decoding tests, either used in research or within a Multi-Tiered Systems of Supports…

For students who show inadequate response to research-based intervention, intensification of intervention using data-based decision making (DBDM) is recommended. There is a paucity of research on upper elementary students related to the efficacy of (a) word reading interventions and (b) DBDM procedures. This randomized controlled trial examined…

Classroom-level influences on literacy skills in kindergarten through Grade 2, and on literacy and numeracy skills in Grades 3, 5, 7, and 9, were examined by comparing the similarity of twins who shared or did not share classrooms with each other. We analyzed two samples using structural equation modeling adapted for twin data. The first, Study 1,…

This study investigated the effects of an instructional technology device, specifically, a computer-based graphic organizer, called the "Real-World Connections Vocabulary" graphic organizer (Ellis, 2015), on vocabulary acquisition for college entrance testing skills of students with high-incidence disabilities. Although graphic…

The overlapping waves model put forth by Robert Siegler emphasizes variability, adaptive choice, and gradual change in children's problem solving. These concepts were applied to emergent reading of an alphabet book with pages of three difficulty levels. Ninety-one kindergartners completed tests of emergent literacy. Twice, about 12 weeks apart,…

Automaticity in word recognition has been hypothesized to be important in reading development (LaBerge & Samuels, 1974; Perfetti, 1985). However, when predicting educational outcomes, it is difficult to isolate the influence of automatic word recognition from factors such as processing speed or knowledge of grapheme-phoneme correspondences.…

The writing skills of autistic university students have received very little empirical attention. Previous research has suggested that autistic people may struggle with writing, in part, due to challenges with Theory of Mind. However, other research indicates that Theory of Mind difficulties are far from universal in autism, varying across…

Helping young children become proficient readers is a critical goal. Research tells us that students who experience difficulty reading in the early years of school often struggle to catch up (Stanley, Petscher, & Catts, 2018; Ozernov, Palchik et al., 2016; Cunningham & Stanovich, 1997; Francis, Shaywitz, Stuebing, Shaywitz, & Fletcher,…

We attempted to strengthen an evidence-based, peer-mediated, first-grade reading program (First Grade Peer-Assisted Learning Strategies [PALS]) by modestly revising its content and adding a repeated-reading (RR) component. In a cluster-randomized trial, we conducted a component analysis of the revised program by creating two versions of it.…

States are increasingly recommending that districts and schools use multi-tiered systems of support (MTSS) to improve reading outcomes for all students. States have also suggested MTSS is a viable service delivery model in response to new state legislation to screen, identify, and treat students with word-level reading disability (i.e., dyslexia).…

Inferencing skills uniquely contribute to the reading comprehension skills of older grade-school and college students. Evidence also suggests that children's reading component skills, such as decoding and language comprehension, differentially contribute to various reading comprehension assessments. However, additional research is needed to…

Motor skills have been linked to language and social development with implications for theory of mind. This study examined theory of mind (attribution of intentions task) in school-age children (N = 62, mean age 8 years; 2 months, standard deviation [SD] = 1;3) in relation to fine motor skills (grooved pegboard), receptive vocabulary (Peabody…
