Children's white matter development is driven by experience, yet it remains poorly understood how it is shaped by attending formal education. A small number of studies compared children before and after the start of formal schooling to understand this, yet they do not allow to separate maturational effects from schooling-related effects. A clever…

We studied the effect of the number and characteristics of siblings (sex, age) on school achievement in several grades (kindergarten, first grade, and fifth grade), in two large French cohorts, with more than 16,000 children. Running linear mixed-effects models, we find that, independently of socioeconomic status, having more siblings is…

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…

Within an Orff-based program implemented in Israel, this mixed-methods study examined the effects of age on emerging rhythmic literacy in children. Participants (N = 132) were kindergarteners (n = 45) and first-graders (n = 87) aged 4 to 7.8 years. The participants performed a rhythm entitled "Rhythm-A" through the body and instrumental…

This study employed a discourse analysis methodology to compare Korean bilingual students in first and third grades by examining different functions and forms of translanguaging in Korean heritage language classrooms in the U.S. By identifying linguistic functions and forms of each translanguaging occurrence, the study presents that the bilingual…

In this article, we present research on eight kindergarten and eight first-grade students' understandings of the arithmetic properties of commutativity, additive identity, and additive inverse during a classroom teaching experiment, selected from a larger study that included 88 students. In this study, we explore the students' types of…

Previous studies reported that a substantial number of students with autism spectrum disorder (ASD) encounter challenges in mathematics as they advance through their education. The present study evaluates the mathematical competence of 17 students diagnosed with ASD who were recruited from first through fourth grades in 12 different mainstream…

Background: Recent research suggested fluent processing as an explanation on why number sense contributes to simple arithmetic tasks--'Fluency hypothesis'. Aims: The current study investigates whether number sense contributes to such arithmetic tasks when other cognitive factors are controlled for (including those that mediate the link); and…

Background: The COVID-19 pandemic created a unique learning experience, characterised by school closures and a shift to online learning. Research suggests that online learning during the pandemic negatively impacted the reading development of elementary school children. However, little is known about the challenges of learning a second language…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results. This study investigated the effects of exposure and age of onset of acquisition (AOA) of L3-English, as well as first and second language (L1/L2) skills and use, in the development of…

There is a lack of research on students' conceptions of giftedness and intelligence, despite recognition of their influence on real-life factors such as achievement and motivation. This paper presents a cross-sectional mixed methods study that investigated Finnish students' (age 6-16 years; N = 1282) implicit conceptions of giftedness and…

Purpose: Both fictional oral narrative and expository oral discourse skills are critical language competencies that support children's academic success. Few studies, however, have examined African American children's microstructure performance across these genres. To address this gap in the literature, the study compared African American…

Following a theoretical framework that recognizes the potential of promotive and inhibitive effects on children's development, this study explored child-, family-, classroom-, and school-level factors as predictors of Latinx (N = 4,590) students' early elementary science achievement. Research Findings: Employing a path modeling approach with…

This investigation aimed to explore the feasibility of implementing the strategic and interactive signing instruction (SISI) framework and its potential to enhance the signed composition skills of four deaf students in a first/second-grade classroom. SISI was adapted from the existing strategic and interactive writing instruction (SIWI) framework…
