Mathematical competence in middle childhood predicts socioeconomic status in adulthood. Therefore, it is important to understand the components that constitute mathematical competence from kindergarten to sixth grade. Using an analytical approach, in this article, I identify three components: understanding numbers, understanding mathematical…

Research Findings: This study aims to examine the latent profiles of parents' mediation and their predictors, as well as links between different profiles and children's problematic media use. A total of 1415 children aged 3-6 years (47.8% boys) and their paired parents were recruited in Shanghai, China and surveyed demographic information,…

We investigated performance levels on conducting continuous two-footed jumping of preschool children (4 years old) to high school students (16 years old) to clarify the developmental progression and sex differences in motor coordination and agility. In total, 450 children (boys: 227; girls: 223) participated in this study. We set 10 obstacles to…

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…

Background: Few studies have examined associations of public library use and shared book reading to kindergarten children's academic skills. Methods: The study sample consisted of 13,385 kindergarten students enrolled in the Early Childhood Longitudinal Study, Kindergarten Class of 2010-2011 (ECLS-K: 2011). Parents reported on public library use…

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…

Multiple studies have shown that children conform to majorities in perceptual judgment tasks against their better knowledge. However, these studies report contradictory results about how conformity develops over age. Here, we study variation in conformity over the course of middle childhood: we examined potential informational and normative…

Working memory is an important component of executive functioning, an area of difficulty for many autistic children. However, executive functioning and working memory are highly malleable throughout childhood, and various student-level and environmental factors play important roles in their development. This study used the Early Childhood…

Inequities have existed in formal public education since its inception in the United States. The educational experiences and outcomes for Black students have historically lagged behind their non-Hispanic, and White peers. This dissertation uses data from The Early Childhood Longitudinal Survey for the Kindergarten Class of 2011 (ECLS-K: 2011) to…

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…

Students' level of academic skills at school entry are a strong predictor of later academic success, and focusing on improving these skills during the preschool years has been a priority during the past 10 years. Evidence from two prior nationally representative studies indicated that incoming kindergarteners' math and literacy skills were higher…

The present study examined, within a longitudinal family-informed design and across middle childhood, the predictive associations between preference for solitude and social wariness, two forms of social withdrawal, and peer difficulties. Specifically, preference for solitude, rather than social wariness, was expected to predict peer victimization…

Leading research argues the distinct importance of earliest detection of childhood behavior problems and the value of discovering subsequent change patterns as children transition through the early education years. This study examined the relative contributions of earliest assessments of children's problem behaviors as compared to the changes in…

The school adjustment of children is the cornerstone of their development, and has been known to be influenced by a variety of factors. This study investigated the effects of peer relationships, theory of mind (ToM), hot executive function (hot EF), and cognitive ability on young children's school adjustment. Participants were 183 children with a…
