The early development of spatial reasoning skills has been linked to future success in mathematics (Wai, Lubinski, & Benbow, 2009), but research to date has mainly focused on the development of these skills within classroom settings rather than at home. The home environment is often the first place students are exposed to, and develop, early…

Many studies examine how bilinguals and monolinguals differ in their executive function abilities at one time-point or cross-sectionally. Fewer examine how these groups of children may differ over time. Using nationally representative data obtained from the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 (ECLS-K:2011), this…

Spanking and parental verbal aggression are potentially toxic stressors that can negatively affect children's academic achievement by disrupting mental skills like executive function. Yet little empirical evidence has been provided for this mediating pathway. This study used data from the Early Childhood Longitudinal Study Kindergarten Cohort of…

Background/Context: The age at which children can enter kindergarten continues to be discussed in both educational research and practice, and the debate for whether to increase kindergarten entry age remains active on both sides. A critical oversight has been the lack of attention paid towards entry age for those students who begin school with a…

This paper used a nationally representative sample of children from the United States to examine the extent to which physical activity and sports participation may promote growth in children's executive functions (EFs), attention, and social self-control over time. Using data from the ECLS-K:2011 (N = 18,174), findings indicated that regular…

This study proposes a new model, termed the multiple membership piecewise growth model (MM-PGM), to handle individual mobility across clusters frequently encountered in longitudinal studies, especially in educational research wherein some students could attend multiple schools during the course of the study. A real data set containing some…

The problem of disproportionality in special education is complex and requires an investigation of multiple factors related to racial, ethnic, linguistic, and socioeconomic backgrounds, school context, and family characteristics. Researchers have debated whether language minority (LM) students are under or overrepresented in special education, but…

This manual provides guidance and documentation for users of the longitudinal kindergarten-fourth grade (K-4) data file of the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011). It mainly provides information specific to the fourth-grade round of data collection. The first chapter provides an overview of the…

This study employs data from both kindergarten cohorts of the Early Childhood Longitudinal Study (n ~ 12,450 in 1998; n ~ 11,000 in 2010) to assess whether associations between preschool participation and children's academic and behavioral outcomes--both at school entry (Mean age = 5.6 years in both cohorts) and through third grade--have changed…

Making a smooth transition to the K-12 (kindergarten through Grade 12) classroom context sets the stage for academic success throughout the life course. Parents' early education-related behaviors are linked with children's adjustment, yet less is known about how parental school readiness beliefs motivate parenting practices at this educational…

Scholars have argued that schools are "equalizers" because inequalities in test scores by race/ethnicity and socioeconomic status (SES) grow faster over summer vacation than over the school year. In this study, we use nationally representative data from the Early Childhood Longitudinal Study--Kindergarten Classes of 1998-1999 and…

Decades of research in the science of reading suggest that using scientifically based reading practices that are aligned with the science of reading will help improve literacy. Literacy is a necessary skill and is critical for a child's overall development. How well children learn to read in school can impact their future success. This mixed…

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…

Teachers provide emotional and behavioral supports essential for success in the classroom. This study examined the roles of child interpersonal skills, teacher expectations, and school racial and poverty compositions on the quality of relationships formed between teachers and children. A subsample from the Early Childhood Longitudinal…
