This meta-analysis aims to clarify the relationship between teacher-child interaction and children's outcomes in language, mathematics, literacy, social development, and self-regulation based on the perspective of the Classroom Assessment Scoring System (CLASS). A total of 24 studies with 139 independent effect sizes and 67,919 participants were…

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…

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…

A recent national report heartily supported arts integration as an effective, innovative, and cost-efficient way to address teachers' and students' needs; however, the report called for a better understanding of when, for whom, and what content areas are best served by arts integration methods. The effectiveness of drama-based pedagogy (DBP), a…

Children who are dual language learners (DLLs) often have more difficulty acquiring English early literacy skills than their English monolingual peers. Much remains to be learned about efficacious early literacy instructional interventions and their effects on English early literacy skills of DLLs. The purposes of this systematic review were to…

This meta-analysis examines the effectiveness of a group of instructional approaches (i.e., cooperative, collaborative, and peer tutoring) at improving literacy outcomes for English language learners. Main effects analyses of a sample of 28 experimental and quasi-experimental studies reveal that peer-mediation is more effective for ELLs than…

The authors reviewed all peer-reviewed studies with participants from preschool to Grade 8 for this meta-analysis of morphological interventions. They identified 22 applicable studies. Instructional effects (Cohen's d) were averaged by linguistic outcome categories (morphological sublexical, non-morphological sublexical, lexical, and supralexical)…

The series of articles in this issue test conceptual models of the processes by which levels of educational attainment are passed from one generation to the next. Collectively, the investigations indicate that although proximal family processes mediate the relation between parent education and children's educational achievement, these processes…

Recent governments in the United Kingdom have introduced a number of initiatives aimed at improving the literacy levels of children. Policy and practice should be informed by rigorous evidence, and this evidence should be subjected to critical scrutiny. In the present paper the results of a "tertiary" review of systematic reviews in…

This report systematically reviews research on the outcomes of programs that teach young children in a group setting before they begin kindergarten. Study inclusion criteria included the use of randomized or matched control groups, evidence of initial equality, and study duration of at least 12 weeks. Studies included valid measures of language,…

This What Works Clearinghouse (WWC) topic report addresses reading interventions for students in grades K-3, including core reading curricula, programs, or products to be used as supplements to other reading instruction, programs that focus on staff development, and literacy software. The WWC review on beginning reading focuses on programs…
