Half of kindergarten teachers split children into higher and lower ability groups for reading or math. In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…

This nationwide study examined the relationships among gender, ethnicity, and poverty with fifth graders' (n = 8,741) science performance. Extant fifth grade data files (2003-2004), from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K), were used. An ANOVA test revealed that males performed significantly better than…

This study assessed how socioeconomic status (SES), race/ethnicity, and birth weight interacted to predict differential patterns of body mass index (BMI) growth among U.S. children born in the early 1990s. Three BMI growth trajectories emerged--one above the 50th percentile across the age range of 5 to 14, one in which children rapidly became…

This study examined the effects of computer access and computer use on the science achievement of elementary school students, with focused attention on the effects for racial and linguistic minority students. The study used the Early Childhood Longitudinal Study (ECLS-K) database and conducted statistical analyses with proper weights and…

Disparities in science achievement across race and gender have been well documented in secondary and postsecondary school; however, the science achievement gap in the early years of elementary school remains understudied. We present findings from the recently released Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 that…

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…

Understanding disparities in school readiness among America's children when they begin kindergarten is critically important, now more than ever. In today's 21st century global economy, it is expected that the great majority of children will complete high school ready to enter college or begin a career, and assume their civic responsibilities. This…

Inequalities in education outcomes such as test scores or degree attainment have been at the center of education policy debates for decades. Indeed, the first seminal national report on the state of U.S. education--the 1966 Coleman Report--examined some of these inequalities 50 years ago. Since then, researchers have examined performance gaps by…

A latent growth model was used to investigate the longer term efficacy of phonics and integrated language arts instruction as well as amount of such instruction on children's reading development, using the nationally representative Early Childhood Longitudinal Study data set (kindergarten through fifth grade). Type and amount of instruction were…

Working from a core perspective on the developmental implications of economic disadvantage, this study attempted to identify "family-based" mechanisms of economic effects on early learning and their potential "school-based" remedies. Multilevel analysis of the Early Childhood Longitudinal Study-Kindergarten Cohort revealed that…

This study addressed concerns about the potential for differential gains in reading during the first 2 years of formal schooling (K-1) versus the next 2 years of schooling (1st-3rd grade). A multilevel piecewise regression with a node at spring 1st grade was used in order to define separate regressions for the two time periods. Empirical Bayes…
