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…

Recent federal, state, and district policies that have mainstreamed English language learner (ELL) students into general, English-only elementary school classrooms have raised questions among educational stakeholders about the widespread effects of these policies. Most research has focused on the outcomes of ELL students; almost nothing is known…

Teachers require knowledge of the unique skills that each child brings to the classroom in order to effectively target instruction towards students' learning needs. Despite substantial investments in programs aimed at enhancing teacher knowledge of individual students' skills (KISS), we know surprisingly little about how KISS is distributed or how…

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.…

Multilevel modeling was used to investigate the relationship between poverty status, mathematics achievement gains, and behavioral engagement in learning over kindergarten. Data included information on 11,680 poor, low-income, and non-poor kindergartners from the Early Childhood Longitudinal Study-Kindergarten Cohort of 1998-1999 (ECLS-K). Results…

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…

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…

Teachers' subjective understandings of their students' cognitive abilities have important implications for classroom interactions, children's access to resources and opportunities, and educational equity more broadly. Using nationally representative data and three-level hierarchical linear models, this study explored the links between teacher…

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…

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…
