Low mathematics achievement in the United States has led to the recent advances in the development and evaluation of Tier 2 mathematics interventions designed to close gaps in mathematics that exist at school entry and prevent these gaps from widening. Because Tier 2 mathematics interventions are generally effective for improving mathematics…

Executive functions (EF) and task persistence are key factors in academic development. However, EF and persistence have rarely been examined together, and it remains unclear whether these two constructs are independently related to intellectual development. The present study addressed this gap by examining whether EF and persistence in…

Young children have informal knowledge of fractions before learning about fraction symbols in school. In the current study, we followed 103 children in the Mid-Atlantic United States from the fall to the spring of first grade to characterize the development of individual differences in early informal fraction knowledge, as well as its relation to…

This study explored whether executive functioning skills and maths test anxiety were associated with children's untimed and timed algorithmic computational performance and their discrepancy. It also investigated whether such relations were moderated by children's basic maths fact fluency. One hundred and thirty third-graders were rated by teachers…

The role of play in early elementary education (K-2) generates dichotomous opinions, and more research is required to support efficacious pedagogical decision-making. This pilot study explored the effects of pedagogical approaches on Title I kindergarten students' executive function (EF) to test the hypothesis that children, especially those from…

Using the Early Childhood Longitudinal Study Kindergarten Cohort (2010-2011), this study is the first to investigate predictors of kindergarten science achievement and growth across elementary school--English language proficiency (ELP), executive functioning, math and reading achievement, parent-engaged science and math activities, and classroom…

Children's ability to discriminate nonsymbolic number (e.g., the number of items in a set) is a commonly studied predictor of later math skills. Number discrimination improves throughout development, but what drives this improvement is unclear. Competing theories suggest that it may be due to a sharpening numerical representation or an improved…

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…

Background: In several countries, children's math skills have been declining at an alarming rate in recent years and decades, and one of the explanations for this alarming situation is that children have difficulties in establishing the relations between arithmetical operations. Aim: In order to address this question, our goal was to determine the…

Research shows that executive functions (EF) and fine motor skills (FMS) contribute to early academic skills, possibly in overlapping ways. We examine whether and how EF and FMS interact in the concurrent prediction of maths, reading and spelling skills at the start of kindergarten. Structural Equation Modelling (SEM) on data from 1248…

Children's ability to discriminate nonsymbolic number (e.g. the number of items in a set) is a commonly studied predictor of later math skills. Number discrimination improves throughout development, but what drives this improvement is unclear. Competing theories suggest it may be due to a sharpening numerical representation or an improved ability…

Spanking and parental verbal aggression are potentially toxic stressors that can negatively affect children's academic achievement by disrupting mental skills like executive function. Yet little empirical evidence has been provided for this mediating pathway. This study used data from the Early Childhood Longitudinal Study Kindergarten Cohort of…

We aimed to investigate the effects of phonological awareness -- PA, rapid automatised naming -- RAN, visuospatial and verbal working memory -- WM and executive functions -- EF on the reading and arithmetic skills of children with low- to medium-performance levels. Participants were 472 Brazilian children from 3rd to 5th grades. Quantile…

We explored whether and how cognitive measures of executive function (EF) can be used to help classify academic performance in Kindergarten and first grade using nonparametric cluster analysis. We found that EF measures were useful in classifying low-reading performance in both grades, but mathematics performance could be grouped into low,…

This study explored the effects of pedagogical approaches on Title I kindergarten students' executive function (EF) and academic achievement to test the hypothesis that children, especially those from low socioeconomic backgrounds, will benefit when purposeful play is incorporated into learning. Students in the play-based group generally had…
