This study contributes to a growing body of scholarship at the intersection of bilingual education and education policy and examines reclassification, or the transition out of formal English language services in schools, as one potential lever in accelerating or decelerating multilingual learners' science learning. More specifically, it traces…

Multilingual learners (MLs) represent an increasing proportion of public school students. Although much attention has been given to their academic performance in English language arts and math, less research has addressed their academic performance in science, particularly in elementary school. This study leveraged nationally representative data…

Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

Kindergarten is emphasized as a critical first entry into the education system, as politicians and pundits believe kindergartners' success can lead to later academic achievement. Therefore, a comprehensive understanding of kindergarten school readiness data should consider how it is measured and how that affects learning. Using the Early Childhood…

Science, Technology, Engineering, and Math (STEM) education is considered critical and valid for the modern workforce which is strongly enveloped in technology. Therefore, it is imperative to reinforce science and math education and knowledge among students early in their educations. Despite this understanding, most research has focused on the…

This study examines the associations between class size, teacher characteristics, and children's academic achievement in mathematics, reading, and science using a recent, large-scale, longitudinal dataset. Individual fixed effects models, which control for observed and unobserved time-invariant student variables, were employed to conduct analysis…

We analyzed a population-based cohort (N = 10,922) to investigate the onset and stability of racial and ethnic disparities in advanced (i.e., above the 90th percentile) science and mathematics achievement during elementary school as well as the antecedent, opportunity, and propensity factors that explained these disparities. About 13% to 16% of…

Executive functions (EF) are domain-general cognitive skills that predict foundational academic skills such as literacy and numeracy. However, less is known about the relation between EFs and science achievement. The nature of this relation might be explained by the theory of mutualism, which states that development is the result of complex and…

Following a theoretical framework that recognizes the potential of promotive and inhibitive effects on children's development, this study explored child-, family-, classroom-, and school-level factors as predictors of Latinx (N = 4,590) students' early elementary science achievement. Research Findings: Employing a path modeling approach with…

Recent evidence points to the early elementary grades as a pivotal point for the development of science learning trajectories and achievement gaps. Using data from the Early Childhood Longitudinal Study, this study estimates the degree to which time spent on science and the breadth of science topics/skills covered predict science achievement in…

Recent research has indicated that science-based achievement gaps open early in children's educational careers and are explained largely by malleable factors. Two potentially important variables to consider include children's executive function (EF) and learning-related behaviors exhibited in the classroom. These variables have been identified as…

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…

Significant racial and ethnic achievement gaps exist between students in the U.S. by elementary school, although the underlying causes for these achievement gaps differ. One factor for racial/ethnic achievement gaps is between-group differences in socioeconomic status (SES), particularly exposure to poverty. Moreover, other factors contributing to…

In the face of rising economic and social inequality, American parents increasingly seek to promote their children's academic achievement through provision of enriching learning opportunities. In this study, we hypothesized that parental investments in both home and out-of-home learning resources may partially explain socioeconomic disparities in…

This study documents gaps in kindergarten and first-grade science achievement by family income and explores the degree to which such gaps can be accounted for by student race/ethnicity, out-of-school activities, parental education, and school fixed effects. In doing so, it expands on prior research that documents disparate rates of science…
