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).…

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…

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…

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…

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…
