Early literacy skills are essential for children's academic development. This research used a comprehensive approach that included observations, assessments, and interviews with children and educators from various kindergartens, which involved 1040 children and 99 teachers from 71 early childhood institutions. The comparison of difficulties in…

The What Works Clearinghouse (WWC) released a report that applies two methodological approaches new to the WWC that together aim to improve researchers' understanding of how early literacy interventions may work to improve outcomes for students in grades K-3. First, this report pilots a new taxonomy developed by early literacy experts and…

Purpose: The purposes of this alphabet knowledge (AK) tutorial are to provide (a) a description of its developmental sequence, (b) evidence-based assessment considerations, (c) evidence-based intervention guidance, and (d) a discussion of three service delivery models that speech-language pathologists (SLPs) can use when providing intervention…

To learn to read, the brain must repurpose neural systems for oral language and visual processing to mediate written language. We begin with a description of computational models for how alphabetic written language is processed. Next, we explain the roles of a dorsal sublexical system in the brain that relates print and speech, a ventral lexical…

Research demonstrated that a dyslexia diagnosis is mainly given after the most effective time for intervention has passed, referred to as the dyslexia paradox. Although some pre-reading cognitive measures have been found to be strong predictors of early literacy acquisition, i.e., phonological awareness (PA), letter knowledge (LK), and rapid…

The appendices accompany the full report "Using Bayesian Meta-Analysis to Explore the Components of Early Literacy Interventions. WWC 2023-008," (ED630495), which pilots a new taxonomy developed by early literacy experts and intervention developers as part of a larger effort to develop standard nomenclature for the components of literacy…

We conducted a secondary analysis of data from a randomized control trial to explore this question: Does "response/no response" best characterize students' reactions to a generally efficacious first-grade reading program, or is a more nuanced characterization necessary? Data were collected on 265 at-risk readers' word reading prior to…

The purpose of this study was to examine the efficacy of the Children's School Success (CSS) curriculum for 4-year-old children enrolled in preschool programs designed to prepare them for success in their early public school grades. The study took place in preschool classes located in five regionally distributed states, all of which were inclusive…

Having strong alphabet knowledge early in life is a powerful predictor of long-term reading and academic outcomes. Upon tracking the alphabet knowledge of 172 children enrolled in their first year of Head Start, we identified that most of the children could name fewer than 10 letters at the beginning of the academic year. Approximately, one third…

Researchers report that early intervention can reduce and eliminate reading difficulties for early readers. What Works Clearinghouse evaluated several phonological awareness interventions, but only one had positive effects on alphabetics and one had potentially positive effects on phonological processing and alphabetics. Additionally, the most…

For two decades, it has been recommended that assessment of literacy for preschool children be conducted in a child's primary language. However, only a few literacy assessments have been validated with a preschool, Spanish-speaking population. The purpose of the present study was to test the latent structure of the Phonological Awareness Literacy…

This study examined the effects of receiving multiple intervention services on the language, literacy, and general development of preschool children from low-income families. By employing a hierarchical linear model on a sample of 1436 children, developmental outcomes of four-year-old children receiving varying numbers of intervention services…

Purpose: As part of this clinical forum on curriculum-based intervention, the goal of this tutorial is to share research about the importance of language and literacy foundations in natural environments during emergent literacy skill development, from infancy through preschool. Following an overview of intervention models in schools by Powell…

This study examined the classroom writing environment in 31 Head Start classrooms, and explored the relations between the writing environment, children's (N = 262) name-writing, and children's letter knowledge using pathway analysis. Our analyses showed that Head Start classrooms provided opportunities (i.e., writing materials and teachers'…

The current study examined whether Head Start children who experienced a high-quality preschool intervention, "Exceptional Coaching for Early Language and Literacy" ("ExCELL"), as three-year-olds began the subsequent pre-kindergarten (or four-year-old) year with stronger language and literacy skills than same-age peers who…
