A student's socioeconomic status (SES) has a significant relation to their academic achievement. Much of this work has explored this in math and reading, but less is known about how SES relates to science achievement, particularly in the early grades. Using quantile regression with nationally representative data, we explored this relation in…

Research Findings: This study examined age-based developmental trajectories of four key number sense (NS) skills within an accelerated longitudinal design. Using data from 408 preschoolers, ages 45 to 68 months, linear and latent basis growth curves were evaluated. Results indicated growth across NS skills was best represented as nonlinear for all…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of initial variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

The effectiveness of Tier 2 interventions may depend on the variability of student skills within an intervention group. We investigated the effect of pretest variability within intervention groups using data from a large-scale study of ROOTS, a Tier 2 kindergarten mathematics intervention. Our research questions were as follows: Does mathematics…

Objective: Executive Function (EF) is thought to be a core component of various cognitive processes. Two common ways to measure EF are through report-based measures that assess EF by collecting informant(s) reports on children's behaviors, and performance-based measures that assess EF through the completion of a task related to EF dimension(s).…

Background: Pre-k convergence refers to the tendency for the positive effects of pre-k on children's academic skills to diminish over time, observed across decades of observational and experimental studies (Ansari et al., 2020). Researchers have tested multiple mechanisms to explain convergence, with mixed results; none of the proposed mechanisms…

Research Findings: Self-regulation is an important determinant of children's developmental outcomes, but little research has explored its different facets simultaneously. This study aims to explore a sample of Chinese children's behavioral, cognitive and emotional self-regulation characteristics by examining their gender and age differences,…

The study examines students' skills at kindergarten entry and gains in skills across the kindergarten through first-grade period (pre-COVID-19) for predicting literacy, language, math, inhibitory control, and social-adjustment outcomes in the spring of fourth grade, after schools reopened. In a large US school district, longitudinal data were…

Low cost, non-invasive instruments for the identification of high academic potential in early childhood education and care are scarce, and the complexity of cognitive development indicates that combinations of screening instruments are needed. This study investigates the reliability and validity of three instruments (individually and in…

Structural equation modelling was used to investigate the predictive associations between kindergarten developmental, socio-behavioural, and biotic influences on third grade achievement among a nationally representative sample of low-SES children. The findings validate the understanding that developmental and learning trajectories start early in…

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…

We investigated whether the cool and hot executive functions (EFs) exhibited by kindergarteners could predict their academic achievement in the middle grades of elementary school. The study assessed the cool and hot EF of 48 Japanese kindergartners (M = 78.12 months) and then measured these same children's academic achievement in language and…

The purpose of this mixed-methods study was to continue the efforts of other researchers in determining whether enrollment in a Pre-K classroom had any impact on students' literacy and math achievement scores in kindergarten. The researcher conducted a two-way repeated measure ANOVA model for the study. The study sample included 6 teachers and 76…

Background: Socioeconomic gaps in children's academic and social skills are large upon Kindergarten entry (von Hippel, Workman, and Downey 2018; Reardon 2011; Reardon and Portilla 2016). Preschool programs may yield particularly large benefits to low-income students and racially minoritized groups and may be promising for reducing inequalities…

Individual characteristics of neighborhood context, like concentrated socioeconomic disadvantage, are associated with children's cognitive development, including their academic skill development and executive functions. However, questions remain regarding how neighborhood structural, process, and physical features uniquely predict children's…
