Fractions are a challenging mathematics topic for many elementary and middle school students, and even for adults. However, a growing body of developmental research suggests that young children can reason about visually presented proportions, well before fraction instruction, providing insight into how fractions might be introduced to improve…

This study considers a contextualized approach to grammar instruction, asking: "Does embedded instruction using published authors as mentors improve grammar and usage for young writers?" Twenty-three students in one second-grade classroom participated. Students were taught grammar conventions through use of mentor texts for 45 minutes a…

Algebraic thinking is an important part of mathematical thinking, and researchers agree that it is beneficial to develop algebraic thinking from an early age. However, there are few examples of what can be taken as indicators of young students' algebraic thinking. The results contribute to filling that gap by analyzing and exemplifying young…

Researchers in educational measurement use Differential Item Functioning (DIF) to examine whether test items are functioning uniquely across subgroups of test participants while taking into account their ability level. DIF is essential for test validity arguments, thus making it a necessary part of validity studies. This study examines DIF across…

The purpose of this quantitative comparative research was to determine if there was a statistically significant main effect of teaching method (project-based vs traditional) on second-grade students' learning in mathematics and if gender differences exist between the scores of male and female students in general and the scores of male and female…

Numerous research based social emotional learning curriculums are available to school districts. The purpose of this study was to examine the potential impact of Second Step, a researched social emotional learning curriculum, and the impact it had on kindergarten, first grade, and second grade students' discipline in school. This…

This study aimed to examine whether a computational thinking (CT) intervention related to (a) number knowledge and arithmetic (b) algebra, and (c) geometry impacts students' learning performance in primary schools. To this end, a quasi-experimental, nonequivalent group design was employed, with 61 students assigned to the experimental group and 47…

A longitudinal study was conducted to identify unique sources of individual differences in later understanding of the equal sign as a relational symbol of equivalence (i.e., formal understanding of mathematical equivalence). The sample included 141 children from a mid-sized city in the Midwestern United States (M[subscript age] = 6 years, 2 months…

Stories live within us and shape our identities. What opportunities do students have to share their stories during the learning of mathematics? How can storytelling enhance the development of mathematical identities? In this article, the author shares reasons for and examples of ways that storytelling in mathematics can support the development of…

We examined how children (N = 448) with separate or co-occurring developmental language disorder (DLD) and dyslexia performed on school-based measures of academic functioning between second and fourth grades. Children were recruited from 1 school district in the U.S. state of South Carolina via classroom screenings and met common research criteria…

A contributing factor to the loss of play in many early childhood classrooms is a sharp separation between literacy learning as serious, even urgent, academic work and play as optional, socially-beneficial-at-best, fun. To recenter play in the academic curriculum, early childhood educators must not only demonstrate how play benefits the existing…

Background: Spelling is a prevalent strategy to teach children to read. However, research on the mechanism underlying the contribution of spelling to reading comprehension in Chinese children is limited. Methods: The primary aim of this study was to investigate the concurrent and longitudinal associations between spelling and reading comprehension…

Studies on the relation between children's reading motivation and early developmental stages of reading competence are rare and have neglected on-line measures of reading skill (e.g., eye movements indicating word decoding). For this reason, we investigated the effects of intrinsic and extrinsic reading motivation on the efficiency of reading…

There is growing evidence that increased physical fitness and physical activity (PA) rates are positively associated with academic achievement. Recent efforts toward Comprehensive School Physical Activity Programs (CSPAP) include the use of PA breaks during academic learning activities. This study examined the acute and chronic effects of PA…

Developmental dyscalculia (DD) is a mathematics learning disorder that affects approximately 5% to 7% of the population. This study aimed to detect the underlying domain-specific and domain-general differences between DD and typically developing (TD) children. We recruited 9-year-old primary school children to form the DD group via a 2-year…
