This study aimed to determine the effects of the Active Early Learning (AEL) childcare center-based physical activity intervention on early childhood executive function and expressive vocabulary via a randomized controlled trial. Three-hundred-and-fourteen preschool children (134 girls) aged 3-5 years from 15 childcare centers were randomly…

Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in…

The academic achievement places children on a positive trajectory for their lifespan. The aim of this study was to examine the academic trajectories of children in out-of-home care (OOCH) and whether kinship care has a protective effect relative to nonkin foster care. The sample analyzed for this study consists of 519,306 racially diverse youth in…

Object exploration is considered a driver of motor, cognitive, and social development. However, little is known about how early childhood education and care settings facilitate object exploration. This study examined if children's exploration of objects during free play was facilitated by the use of particular spatial components (floor, tables,…

Experimental research demonstrates sustained high-quality early care and education (ECE) can mitigate the consequences of poverty into adulthood. However, the long-term effects of community-based ECE are less known. Using the 1991 NICHD Study of Early Child Care and Youth Development (n = 994; 49.7% female; 73.6% White, 10.6% African American,…

This paper used the Early Childhood Longitudinal Study-Birth Cohort (N = 1,258) to examine the influence of hilevels of cognitive stimulation from mothers, fathers, and childcare providers at 24 months and children's pre-academic skills at 48 and 60 months in two parent families. Results from path analysis showed direct positive effects of…

Although professional development is widely used to improve the impacts of early childhood education, little is known about the conditions under which such interventions promote child outcomes. This study applies newly developed methods for quantifying intervention impact heterogeneity to understand whether educators' collective workplace stress…

This meta-analysis studies the association of pedagogical processes in early childhood care and education with outcomes in two academic domains: language and literacy as well as mathematics. It synthesizes evidence from 17 longitudinal studies in nine European countries with 16,461 children in regular center-based care spanning the period between…

This study considered the quality and stability of infant and toddler nonparental child care from 6 to 36 months in relation to language, social, and academic skills measured proximally at 36 months and distally at kindergarten. "Quality" was measured separately as caregiver-child verbal interactions and caregiver sensitivity, and…

This study examined the value of using a group-centered approach to evaluate process quality of early childhood education and care (ECEC). Is observed support of group processes a different aspect of classroom quality, and does it predict children's collaborative play in ECEC in the Netherlands? In two play situations, 37 teachers and 120 two- to…

This study is the first to test whether receipt of a federal child care subsidy is associated with children of immigrants' school readiness skills. Using nationally representative data (n ˜ 2,900), this study estimates the associations between subsidy receipt at age 4 and kindergarten cognitive and social outcomes, for children of immigrant…

In this Norwegian study, bidirectional relations between children's behavior problems and child-teacher conflict and closeness were examined, and the possibility of moderation of these associations by child-care group size was tested. Eight hundred and nineteen 4-year-old children were followed up in first grade. Results revealed reciprocal…

Caregiving is requisite to wholesome child development from the beginning of life. A cross-sectional microgenetic analysis of six caregiving practices across the child's 1st year (0-12 months) in 42,539 families from nationally representative samples in 38 low- and middle-income countries is reported. Rates of caregiving varied tremendously within…

The sociopolitical context of Norway includes low poverty rates and universal access to subsidized and regulated Early Childhood Education and Care (ECEC). In this context, the association between family income dynamics and changes in early child behavior problems was investigated, as well as whether high-quality ECEC buffers children from the…

This study examined the third-grade outcomes of 11,902 low-income Latino children who experienced public school pre-K or child care via subsidies (center-based care) at age 4 in Miami-Dade County, Florida. Regression and propensity score analyses revealed that children who experienced public school pre-K earned higher scores on standardized…
