"Pre-K Mathematics" is a supplemental mathematics program focusing on a range of mathematical concepts to help develop children's informal mathematical knowledge. The "Pre-K Mathematics" program includes teacher-led, small-group mathematics activities that are engaging and hands-on, as well as caregiver-child activities that…

In recent years, a new movement to raise awareness about early math learning has been growing in the U.S., driven by research showing that foundational math knowledge is more predictive of later success in school than nearly any other indicator, including literacy. This awareness of the importance of early math has led to an increasing focus among…

As applications of multilevel modelling in educational research increase, researchers realize that multilevel data collected in many educational settings are often not purely nested. The most common multilevel non-nested data structure is one that involves student mobility in longitudinal studies. This article provides a methodological review of…

The Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011) is the third in a series of longitudinal studies of young children conducted by the National Center for Education Statistics (NCES), within the U.S. Department of Education's Institute of Education Sciences. The ECLS-K:2011 collected information about the early…

"Math Expressions" is a curriculum for students in prekindergarten through sixth grade that aims to build students' conceptual understanding of mathematics and to develop fluency in mathematical problem solving and computation. The curriculum encourages student learning of mathematics through real-world situations, visual supports such…

Policymakers have advocated academic skills building at kindergarten as a way of improving student achievement. However, early childhood educators have concerns with this policy as gains in achievement may come at the expense of children's social-emotional skills. Using a nationally representative data set of kindergartners, we find that advanced…

Policy research highlights educational disparity between Blacks and Whites, thereby, emphasizing the need to determine malleable ecological factors that support the positive development and learning of Black children during the early schooling years. The purpose of this study was to examine whether change in home environment and neighborhood were…

The Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011), is collecting information about the early educational experiences of a nationally representative sample of children who were in kindergarten or who were of kindergarten age in ungraded classrooms or schools in the 2010-11 school year. The data collection began in…

In this study we use data from the Early Childhood Longitudinal Survey third- and fifth-grade samples to investigate teacher judgments of student achievement, the extent to which they offer a similar picture of student mathematics achievement compared to standardized test scores, and whether classroom assessment practices moderate the relationship…

Closing achievement gaps--disparities in academic achievement between minority and white students, and between low-income and higher-income students--has long been an unrealized goal of U.S. education policy. It has now been 60 years since the Supreme Court declared "separate but equal" schools unconstitutional in "Brown v. Board of…

Overview: A recent evaluation of children who had participated in the Parent-Child Home Program (PCHP) as toddlers found that at kindergarten age, these children were performing at levels expected for their age, despite the fact that they had multiple factors putting them at risk for school failure. The Study: In the winter and spring of 2002, 135…

Using multilevel models of data from the Early Childhood Longitudinal Study-Kindergarten Cohort (N = 20,356), the authors find that parental involvement in education partially mediates the association between family poverty and children's math and reading achievement in kindergarten, but differences exist across race. In Asian families, poor and…

This report shows the rural disparities in the baseline data of the Birth and Kindergarten Cohorts of the national Early Childhood Longitudinal Study (ECLS). The National Center for Rural Early Childhood Learning Initiatives, known as Rural Early Childhood, commissioned Child Trends to perform the analysis of key indicators of child well-being and…

This paper will review several important constructs in the area of social and emotional development of children in grades 2-5. The importance of social and emotional development has become increasingly evident in light of new research on the brain and the development of programs to prevent social and behavioral disorders in youth. This review will…
