The current study examined the contexts in which a preschool teacher professional development intervention was more versus less effective in improving student outcomes. We used a fixed intercept, random coefficient (FIRC) modeling approach to explore the contextual characteristics inside and outside school walls that predicted differential…

Pre-kindergarten (Pre-K) programs typically improve early academic skills, but those gains too often disappear after children transition to elementary school. At least three hypotheses explain this "fade-out" of Pre-K effects: Pre-K does not focus on the "trifecta skills" that uniquely support subsequent learning and…

The neighborhood literature consistently documents associations between neighborhood socioeconomic status (SES) and child development. Yet, this approach may miss important heterogeneity in neighborhood resources (e.g., libraries, doctors' offices) that have important implications for children. Moreover, the mechanisms that explain the relation…

Children's Approaches to Learning (AtL) represents how children seek learning opportunities in their classrooms. It can include children's persistence, attention, and initiative. It has often been studied using a composite of a teacher-rated scale. However, person-centered approaches may account for heterogeneity in children's learning approaches,…

The present study reports associations between features of directly observed classroom processes and school readiness skills across the academic year for 1498 children enrolled in publicly funded pre-K programs in a large and diverse county. In models adjusting for a range of child and family covariates, evidence was detected for the separate, and…

This study examined whether pre-K benefits persist through the end of first grade and the extent to which persistence differs based on outcome domains, subsequent classroom environments, and key subgroups of children. Data from 2,351 children living in a large and diverse county in Virginia revealed that the initial benefits of pre-K for academic…

One widely used tool that captures the process quality of preschool classrooms, including interactions between teachers and children, is the Classroom Assessment Scoring System-Preschool (Pre-K CLASS; Pianta et al. 2008). The Bill & Melinda Gates Foundation funded Mathematica to conduct a literature scan to search for recent studies analyzing…

Research Findings: The aim of the current study was to examine the extent to which the effects of preschool classroom quality on children's mathematics is moderated by executive functioning (EF) during the preschool year. The study sample included 102 children (M age = 53.57 months [SD = 5.42]; 49% male) and one of their parents recruited from 26…

Dual language learner children (DLLs) benefit from early childhood education (ECE) and learning multiple languages, but research has predominantly focused on English monolingual children, with limited insight on the ECE and early development of DLLs. This study investigated whether DLLs' developmental assets assessed at pre-k entry (i.e. English…

General measures of process quality are widely used in the early childhood education (ECE) field. However, the evidence regarding associations between the most widely used process quality measure, the Classroom Assessment Scoring System (CLASS; Pianta et al., 2008), and children's school readiness gains during the preschool year is mixed. Using…

A classroom randomized efficacy trial conducted over four years in 7 community-based preschool and 6 Head Start programs investigated effects of the Second Step Early Learning (SSEL) curriculum on end of preschool executive functioning (EF) and social-emotional (SE) skills in low-income children. Outcomes are reported for n=770 four-year-olds…

Research Findings: The increase in young Latino Dual Language Learners (DLLs) attending early care and education (ECE) programs has led to a focus on assessing classroom quality for DLLs, to evaluate the quality and impact of their early educational experiences. Experts have advocated for the use of multiple classroom observation tools (i.e.,…

The primary purpose of the 2017-2018 NC Pre-Kindergarten (NC Pre-K) Evaluation was to examine the effectiveness of the NC Pre-K Program using a randomized controlled trial (RCT) design. The major issue addressed by this type of study is around the benefits of offering children access to enrollment in NC Pre-K. An RCT is considered the…
