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…

The need for effective reading instruction is of high priority. One of the many ways that students learn to read is through multisensory instruction. Elementary-age students struggle to become proficient readers. This is due to the lack of reading skills. The goal of reading is comprehension. As students learn letter-sound correspondence,…

Background: Failure to learn early reading skills leads to lower reading comprehension later in elementary school (Double et al., 2019; Paige et al., 2019), which can then lead to poverty, underemployment, and increased likelihood of being incarcerated (World Literacy Foundation, 2018). Early reading skills are best developed in kindergarten…

Fluency with skills that operate below the word level (i.e., sublexical), such as phonemic awareness and alphabetic knowledge, may ease the acquisition of decoding skills (Ritchey & Speece, 2006). Measures of sublexical fluency such as phoneme segmentation fluency (PSF), letter naming fluency (LNF), and letter sound fluency (LSF) are widely…

The importance of letter sound knowledge (LSK) as a precursor to later literacy skills has been well-documented. Since English language learners (ELLs), or students who first acquired a language other than English, continue to underperform in reading compared to their English-speaking peers, they are particularly at-risk for reading and academic…

Central questions in the study of visual word recognition and developmental dyslexia are whether early lexical activation precedes and supports decoding (a dual-stage view) or not (dual-route view), and the locus of deficits in dysfluent reading. The dual-route view predicts early word frequency and length interaction, whereas the dual-stage view…

Two groups of freshman students, enrolled in a Vocabulary I and Reading I courses, participated in the study. Before instruction, both groups took a recognition (vocabulary) and a production (oral reading) pre-test. Comparisons of the pre-test scores showed no significant differences between the experimental and control group in decoding skills…

The purpose of this study was to evaluate the effects of an 18-day summer tutoring program in which graduate student tutors delivered 15 minutes of differentiated reading instruction (DRI) and a 30-minute interactive read-aloud (IRA) lesson each day. Students in grades K-5 (N = 179) attending a summer program at one urban elementary school…

Recent efforts to motivate parents' involvement in their child's literacy development involve informing parents about how to incorporate literacy development into daily routines. Teacher leadership and communication are critical--the more teachers encourage and assist parents and caregivers in supporting their child's literacy development, the…

Reading Horizons partnered with LearnPlatform by Instructure to investigate the relationship between teacher implementation of Reading Horizons Discovery (RHD) and student literacy outcomes. The study involved 83 educators and 1,242 students across seven elementary schools in North Carolina during the 2022-23 school year. Researchers used mCLASS…

Quantifying the decoding difficulty (i.e., 'decodability') of text is important for accurately matching young readers to appropriate text and scaffolding reading development. Since no easily accessible, quantitative, word-level metric of decodability exists, we developed a decoding measure (DM) that can be calculated via a web-based scoring…

Background: Reading development in agglutinating African languages is a relatively underresearched area. While numerous studies highlight the low comprehension levels among learners reading in African languages in South Africa, little has been done to probe beneath this 'comprehension iceberg' in terms of decoding skills. Aim: As a tentative step…

Learning to read begins at home through everyday parent-child interactions, long before children attend school. Parents' continuing support of literacy development throughout elementary school positively affects their children's reading ability. Many recent efforts to motivate parents to be involved in their child's literacy development involve…

Background: We examined the component skills of reading comprehension (i.e., letter sound knowledge, syllable reading fluency, decoding fluency, text or oral reading fluency and listening comprehension) and their structural relations using data from three sub-Saharan African languages with transparent orthographies in a multilingual context.…
