In this brief, we use a nationally representative sample of ever-English learners (ELs; N = 783) to examine relations between EL concentration within classrooms and reading growth between kindergarten and Grade 5. Piecewise growth models were used to estimate relations for four developmental periods (K-1, Grades 1-2, Grades 2-3, and Grades 3-5).…

In this brief, we use a national representative sample of ever-English learners (N = 783) to examine relations between English learner concentration within classrooms and reading growth between Kindergarten and Grade 5.

Using the Early Childhood Longitudinal Study, Kindergarten Cohort of 1998 (ECLS-K, 98), a nationally representative sample of kindergarteners in the United States, we investigated the relationship between approaches to learning and spring reading achievement with particular emphasis on classroom and school-level differences. We employed…

We apply "value-added" models to estimate the effects of teachers on an outcome they cannot plausibly affect: student height. When fitting the relatively simple models that are widely used in educational practice to New York City data, we find the standard deviation of teacher effects on height is nearly as large as that for math and…

Our nation's classrooms have become increasingly racially and ethnically diverse. Given these demographic changes, many policymakers and practitioners have expressed the need for increased attention to how teacher diversity might be linked to reducing racial/ethnic differences in teachers' ratings of social-emotional skills for students of color.…

Research Findings: Relying on a newly released national data set of kindergarten students from the 2010-2011 school year (Early Childhood Longitudinal Study-Kindergarten Class of 2010-2011), the findings suggest that having a greater percentage of same-needs classmates positively boosts both achievement and socioemotional outcomes among…

Parent engagement in early care and education (ECE) settings is a component of high quality childcare, yet little is known about mechanisms of parent engagement in centre-based care. Using a nationally representative U.S. sample, we examined centre, classroom, and teacher characteristics associated with practices ECE providers use to engage…

Over the past 20 years, the number of teacher's aides in the United States has more than doubled, potentially in response to the growth of special education programs now taking place in general education schools. Surprisingly, little research at all has focused on the role that teacher's aides may play in improving student achievement, and no…

Using data from the Early Childhood Longitudinal Study-Kindergarten Cohort (N = 13,970), we examined whether two aspects of school-family connections, parental involvement and communication quality, accounted for the association between classroom composition and children's academic and socioemotional functioning following the transition to…

This study examines how affective (student-teacher relationships) and sociological factors (race) interact in educational settings to shape differential educational experiences for diverse subgroups. Studying these factors in isolation only partially explains the mechanisms that drive outcomes for students, especially those belonging to…

Many kindergarten teachers use ability groups to differentiate instruction in reading and math. Ability group placement should depend primarily on student achievement, but critics charge that placement is biased by socioeconomic status (SES), gender, and race/ethnicity. We predict group placement in the Early Childhood Longitudinal Study of the…

This article explores how the associations between student achievement and achievement growth influence our understanding of the role schools play in academic inequality. Using nationally representative data from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 (ECLS-K:2011), we constructed parallel growth and lagged score…

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…

There are few areas of school organization that reflect more dissatisfaction than how to structure the education of adolescents in the middle grades. This study uses multilevel models on nationally representative data provided by the Early Childhood Longitudinal Study to investigate the relationship between schools' middle-level grade span and…

Self-regulation is a critical component of school readiness and success. Practices for supporting self-regulation may be advanced by a better understanding of factors characterizing children at risk for challenges and contextual mechanisms associated with desirable developmental trajectories. The current study leverages a large national data set…
