Significant socioeconomic disparities exist across the neighborhoods where children grow up today, which may exacerbate inequities in children's educational opportunities (Leventhal et al., 2015; Leventhal & Dupere, 2019; Mijs & Roe, 2021; Reardon et al., 2018). Prior research documents associations between neighborhood socioeconomic…

In this manuscript we show how readalouds can significantly enrich student vocabulary and comprehension by demonstrating enhancements that will foster student learning and language development. We anchor our examples to empirical evidence demonstrating that the content of a readaloud (i.e., the what we teach) as well as the quality of the…

Zambia has a large, autonomous community schooling system that formed during the nation's transition from a socialist economy. The community schooling system has expanded during the past 20 years to increase education access in remote areas. Estimates suggest that the number of Zambian community schools has increased from 100 schools in 1996 to…

The present study examined teacher sensitivity as a potential moderator of the relationship between children's temperament in infancy and their social development in first grade. Using data from the Study of Early Child Care and Youth Development (NICHD SECCYD), we found that first grade teachers who were sensitive and responsive to students'…

Observational studies comparing child outcomes in early care and education classrooms of differing quality are often confounded by between-child differences. A within-child design, tracking children across contexts, can identify the effects of quality with less confounding. An analysis of Australian children (N = 1128, mean age 5 years, 48%…

This study examines whether the physical location of Pre-K programs--whether in elementary school buildings or stand-alone centers--leads to differences in student outcomes in elementary school. Over the past several decades, public investment in Pre-K programming has burgeoned. According to the National Institute for Early Education Research, 32…

This study investigated the vocabulary development of children (N = 547) from linguistically and socioeconomically diverse classrooms in Germany from age 3 in preschool to age 7 in Grade 1. The results showed that for dual language learners (DLLs, n = 107) growth rates in their German majority language skills varied over classrooms. Compared to…

Using data from the NICHD Study of Early Child Care (n = 1364), we examined how experiences in early childcare (ECE) and in families from 6 to 54 months predicted the development of first-grade prosocial behaviour (PSB), a core component of social and emotional success. SEM analyses revealed several key pathways: (1) both ECE process quality and…

This appendix provides additional details on the underlying data, statistical models, and results presented in "The Big Lift Descriptive Analyses: Progress across Three Kindergarten Classes." First the authors describe how they created each control and outcome variable and its source (e.g., parent report), followed by an overview of the…

The Big Lift™ (Big Lift), a collective impact initiative extending from preschool through third grade in San Mateo County, California, aims to boost reading proficiency and kindergarten readiness through four programmatic pillars: High-Quality Preschool, Summer Learning, Attendance, and Family Engagement. In this report, the authors present…

Using data from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD), this dissertation examined the relationship between pre-K quality and children's academic achievement at 54 months and in first, third, and fifth grades, controlling for child and family covariates and the…

The purpose of this qualitative case study was to explore the implementation of a Professional Learning Community (PLC) as a professional development model effective in altering teachers' perceptions of their knowledge and skill in teaching developmental writing in grades K-3. This research is necessary to examine how offering teachers…

This report explains the work that has taken place over the last decade in Boston to not only improve pre-K, but to build on the successes of pre-K through reform of classroom environments, instructional practices, and curricula in pre-K, kindergarten, and, more recently, in first and second grade. It is a story of reforming from the bottom up, of…

A growing body of research has shown that high quality early care and education (ECE) is positively related to the development of children's social and academic skills (e.g., Barnett, 2011; Lamb & Ahnert, 2006; NICHD ECCRN, 2006). There is evidence that high quality ECE experiences can improve children's levels of social adjustment (Bierman et…

In this "FastFacts," a state's Department of Education requests information from the Center on Enhancing Early Learning Outcomes (CEELO) on how the research defines skills in social-emotional development, approaches to learning, and executive function, to inform planned revisions to the early childhood indicators of progress for children…
