We investigated the stability and developmental interplay of word reading and spelling in samples of Swedish (N = 191) and U.S. children (N = 489) followed across four time points: end of kindergarten, grades 1, 2, and 4. Cross-lagged path models revealed that reading and spelling showed moderate to strong autoregressive effects, with reading…

Orthographic knowledge is predicted to be central in the process of children's reading development. We examined both the temporal order between orthographic knowledge and each of word reading and word spelling--effectively, which predicts which by including autoregressive controls--and cross-linguistic transfer between English and French for our…

This study aimed to describe 1-year changes in students' vocabulary in written narratives. Secondary aims included examination of accuracy and the relationship between lexical diversity and achievement. Participants included 749 students in first through eighth grades. Within-subjects 1-year change in diversity, productivity, and accuracy was…

Skilled reading involves rapid and automatic word recognition. Through a self-teaching process, phonological decoding during reading is thought to establish the word-specific representations in memory that support efficient word reading. Much is known about orthographic learning during reading; less is understood about this process during…

Although there is a growing research base on Arabic literacy development to inform our understanding of the factors that account for variability in word reading skill, the current body of research is limited by two major constraints. First, although several studies examine one or more early literacy constructs, we were able to locate only two…

Research consistently documents that girls outperform boys in literacy achievement, yet, when considering the starting point--early literacy--we do not have consensus on the origin, meaningful nature, or persistence of such differences. In this two-part study analyzing 5,816 Norwegian students (48.1% girls, average age of 6.1 years), we first…

The Computer-based Orthographic Processing Assessment (COPA) is a newly developed assessment to measure orthographic processing skills, including rapid perception, access, differentiation, correction, and arrangement. In this study, cognitive diagnostic models were used to test if the dimensionality of the COPA conforms to theoretical expectation,…

Assessments of oral reading rate in words correct per minute (WCPM) have proliferated in elementary classrooms. This study explores the similarities and differences among students at the end of second grade who demonstrate low WCPM. Using latent profile analysis, readers with low WCPM compared to peers were identified (n = 2,191) from a state-wide…

Orthographic processing -- the ability to perceive, access, differentiate, and manipulate orthographic knowledge -- is essential when learning to recognize words. Despite its critical importance in literacy acquisition, the field lacks a tool to assess this essential cognitive ability. The goal of this study was to design a computer-based…

The purpose of this study was to examine the effects of word boxes on the phoneme segmentation, word identification, and spelling performance of a sample of children with autism. Three children with autism were selected on the basis of similar performance on early literacy skills as measured by the Dynamic Indicators of Basic Early Literacy Skills…

This is a companion to the What Works Clearinghouse (WWC) practice guide, "Foundational Skills to Support Reading for Understanding in Kindergarten through 3rd Grade" (ED566956). This guide is organized according to the four recommendations and how-to steps from the WWC practice guide. The activities follow the typical developmental…

The study aimed to investigate the spelling performance and the semantic understanding of compound words by 103 Greek primary school children (first through sixth grade). The experimental group comprised of 25 children with spelling difficulties and compared with a control group of 78 children of typical development. Children were asked to spell…

The goal of the What Works Clearinghouse (WWC) Practice Guide, "Foundational Skills to Support Reading for Understanding in Kindergarten through 3rd Grade," is to offer educators specific, evidence-based recommendations for teaching foundational reading skills to students in kindergarten through 3rd grade. The guide suggests…

This study used a within-subjects design to explore two instructional conditions for developing vocabulary in second-grade Spanish-speaking English learners (ELs)--extended instruction and embedded instruction implemented during shared interactive reading. Words assigned to the extended condition were directly taught using a multifaceted approach…

The purpose of this study was to examine how readers build orthographic knowledge for irregular words, defined as words that do not conform to conventional phonics rules and patterns. This study tests my theory that readers use phonological decoding, crosschecking and mental markings to read and spell unfamiliar irregular words. Forty-three…
