Background: In today's fast-paced world, the complexity of family relations is growing. This demands a closer look into the effects of parental marital relationships and parents' involvement on children's literacy outcomes. Objective: The study objective was to examine the connections between parental marital status, parental involvement, and…

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…

The purpose of this quantitative study was to analyze the ECLS-K:2011 longitudinal study to determine the impact the mother's education has on her child's kindergarten academic performance, growth and attainment from kindergarten through fifth grade, and the background characteristics that affect child academic development. This study employed a…

Childhood overweight and obesity are major public health problems in the United States. Children who experience poverty are 1.5 times more likely to suffer with overweight and 1.6 times more likely to have obesity. The extent to which overweight or obesity exacerbates the negative influence of socioeconomic inequality on child academic outcomes…

The specific purpose of this study was to add to the previous research using The Early Childhood Longitudinal Database to examine if there is a difference in the mathematics achievement growth trajectory of African American students based on racial-ethnicity, socioeconomic status, and kindergarten participation (attendance for the first time or…

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…

This study investigated the extent to which class-specific parameter estimates are biased by the within-class normality assumption in nonnormal growth mixture modeling (GMM). Monte Carlo simulations for nonnormal GMM were conducted to analyze and compare two strategies for obtaining unbiased parameter estimates: relaxing the within-class normality…

The piecewise latent growth models (PWLGMs) can be used to study changes in the growth trajectory of an outcome due to an event or condition, such as exposure to an intervention. When there are multiple outcomes of interest, a researcher may choose to fit a series of PWLGMs or a single parallel-process PWLGM. A comparison of these models is…

Half of kindergarten teachers split children into higher and lower ability groups for reading or math. In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…

The purpose of this study was to estimate the longitudinal and reciprocal predictive relations between children's social skills, measured by an adaptation of the frequently used Social Skills Rating Scale, and their standardized academic achievement. A large nationally representative sample of elementary school students were assessed at least…

Spanish-speaking students constitute the largest subgroup of emergent bilingual (EB) students in the United States. Using longitudinal data on a nationally representative sample of Spanish-English EBs, we explore profiles of English reading trajectories and how early individual differences (i.e., early Spanish reading and English oral proficiency)…

This study provides estimates for the impact of centre-based care participation during pre-kindergarten on Latino children's academic readiness skills at kindergarten-entry. Using the ECLS-K:2011 dataset, findings indicate that Latino children who participated in centre-based care during their pre-kindergarten year had significantly higher English…

In education, relative age effects (RAE) are present if a student's age when compared to that of his/her classmates has implications for scores on measures of achievement and performance. Researchers studying relative age have established significant, but inconsistent effects of being relatively older or younger in a grade level on measures of…

Half of kindergarten teachers split children into higher and lower ability groups for reading or math. In national data, we predicted kindergarten ability group placement using linear and ordinal logistic regression with classroom fixed effects. In fall, test scores were the best predictors of group placement, but there was bias favoring girls,…
