This article examines the impact of within-class age differences on educational outcomes, using students' birth months in Madrid's primary schools as a natural experiment. Employing a regression discontinuity design, we analyze third-grade students to investigate these age-related effects. Additionally, we explore whether early childhood education…

This study investigated direct and indirect pathways from listening comprehension (LC) to reading comprehension (RC) via fluent word reading (FWR) in grades 1-3, and path equivalence across these grades. LC's total effects predicting RC range from 0.45 to 0.59 in grades 1-3, a stronger relationship than found in previous studies. Overall, LC's…

This study examined the relationships between word reading and rapid automatized naming (RAN) for objects and letters in Arabic-speaking children with and without dyslexia to determine potential modulating effects of color on naming by comparing children's performance on color and black-white RAN plates. Participants were 114 Arabic-speaking third…

Perceived life satisfaction during the period of childhood and adolescence can be considered a reliable measure of psychological and emotional growth of children and adolescents. The current study aimed to investigate age differences related to social support provided to students (by teachers, classmates, parents and close friends), and its…

The goal of this study was to examine the unique associations of aggression with peer status in a non-Western context. The moderating effects of peer community and teacher closeness at the classroom level and gender and grade at the individual level were considered. Participants were 1954 third to sixth grade students (M[subscript age] = 9.60…

Spelling errors are considered a paramount criterion in the evaluation of written texts. The present study aimed: (1) to describe the developmental path of spelling errors in expository texts written by Hebrew-speaking children from the second to fifth grades; and (2) to reveal the predictive power of cognitive, linguistic and reading variables on…

Math anxiety negatively predicts young children's math achievement. While some researchers have suggested that math anxiety may stem from poor math ability, others have argued that math anxiety occurs at all levels of math ability. An important question is whether math anxiety predicts math achievement over and above foundational math skills. We…

The current study examines the extent to which associations between internalizing problems, body mass index (BMI), and language skills from early (36 months) to late childhood (fifth grade) are due to relatively stable between-child differences, time-specific correlations, or cross-lagged paths. Data from the NICHD study, Early Child Care and…

Purpose: Identifying appropriate targets for vocabulary instruction and determining the optimal sequence for instruction continue to be a challenge. The purpose of this study is to investigate how previously studied lexical characteristics collectively influence children's word learning. Method: A secondary data analysis was conducted using the…

To understand mathematics, children must interpret mathematics symbols. In this study, we designed a brief assessment of mathematics symbols for children in the elementary grades. For each of 23 symbols, children identified the symbol, provided the meaning of the symbol, and used the symbol. We assessed 297 children in Grades 1, 3, and 5. Internal…

Growth in working memory capacity, the number of items kept active in mind, is thought to be an important aspect of childhood cognitive development. Here, we focused on participants' awareness of the contents of their working memory, or "meta-working memory," which seems important because people can put cognitive abilities to best use…

Background: Most previous studies of teaching styles and reading skills have been cross-sectional. Longitudinal research is needed to clarify the direction of effects. The present longitudinal study examined the degree to which differences in teaching styles in the third grade predict the sixth-grade reading performance. The consistency of the…

In the present research, we provide empirical evidence for the process of symbolic integration of number associations, focusing on the development of simple addition (e.g., 5 + 3 = 8), subtraction (e.g., 5 - 3 = 2), and multiplication (e.g., 5 × 3 = 15). Canadian children were assessed twice, in Grade 2 and Grade 3 (N = 244; 55% girls). All…
