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.

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…

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…

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…

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…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

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…

Some education policy analysts have called for increased participation of young children in full-day kindergarten programs as opposed to part-day kindergarten. However, little is known about whether students with disabilities are increasingly attending these programs and what their teachers are like. This study addresses this gap by examining…

Student absenteeism is a barrier to learning and an issue that requires policy intervention. Students with disabilities are of particular concern, as they miss school more often than students in any other demographic group. Affecting a key attribute of school structures, policies promoting full-day kindergarten began as an effort to improve…

Executive function skills are a set of cognitive processes that help individuals to engage in goal-directed behavior and have been linked to benefits in academic achievement and other learning-related outcomes. Recently, there has been interest in understanding how attending center-based preschool may relate to the development of executive…
