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 study explored the extent learners' age variances impacted their achievement in a national education assessment in Ghana and how these were moderated by the types of schools (i.e., private and public) they attended. A multistage sampling method was used, and the data were analyzed using a multilevel modeling technique. The sample comprised…

This research aims to examine the effect of birth month on student achievement as well as social and spiritual development in the classroom. We designed this research as a mixed embedded experimental design, one of the mixed research designs. For the experimental group, first-grade students in a primary school in Aziziye District of Erzurum…

In this study, we explored associations between perception of musical features (pitch, tonality, timing, timbre, and loudness), vocal abilities (singing accuracy, melodic achievement, and rhythmic performance), and cognitive levels (reading accuracy and comprehension, grammar, and math) among children ages 6 to 12. Musical perception abilities…

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 examined 1337 children or adolescents from various educational stages (primary, junior, and senior high school levels) along with their parents. First, we examined the effects of parental education anxiety, children's academic anxiety, children's self-academic achievement expectation, and parental self-blame on the progression of…

Purpose: Good verbal signals and low background noise are key factors for all children to maximize understanding of what is being taught. Classroom shape, surroundings, and even furnishings change how the environment "sounds" and how speech is "heard" in the classroom. Classroom acoustics is perhaps one of the most important,…

The article explores the interactions between learners' age and achievement in rural and urban primary schools in a national education assessment in Ghana. The study sample comprised 12,207 learners from 349 public schools, and the data were analysed using multilevel modelling. The findings revealed a statistically significant and negative impact…

Children show marked improvements in executive functioning (EF) between 4 and 7 years of age. In many societies, this time period coincides with the start of formal school education, in which children are required to follow rules in a structured environment, drawing heavily on EF processes such as inhibitory control. This study aimed to…

This study examined the effect of class sizes on differences in the trajectories of elementary school students' long-term Japanese language achievement by analyzing panel data composed of standardized achievement test scores at five points from around the end of first grade to around the end of fifth grade. The data for 103 schools, 162 classes,…

High achievers vary in terms of the constraints and difficulties they encounter on the road to success. The present study investigates whether and how children consider the constraints one overcomes in their beliefs and reasoning about academic achievement. Four- to nine-year-olds (N = 98, 57 girls, 41 boys) and their parents (N = 92, 80 females,…

Gender differences in teacher ratings of academic performance, social skills, and externalizing behavior were examined from fourth through seventh grade in a group of 1,023 students from 65 primary schools. Cohen's "d" and "t" tests and were used to report the magnitude of gender differences, and structural equation modeling…

Mobile devices in the primary school classroom may improve literacy and numeracy learning, though concerns about risk of bias and uncertainty about modes of effect limit conclusions. This review gathered evidence on how mobile devices (including tablets, mobile phones, and handheld digital games) are used in primary school classrooms to help…

As an important part of adolescents' social capital, teacher-student relationship (TSR) and parental involvement (PI) are important for student learning. However, we know little about how PI works with TSR in relation to adolescents' learning outcomes. The present study aimed to examine the association between TSR and adolescents' learning…

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…
