Students with Attention-Deficit/Hyperactivity Disorder (ADHD) are struggling writers. Yet no comprehensive model has been validated to explain their poor writing outcomes. This study aims to test whether an extended version of the Not-So-Simple View of Writing (NSVW) model can describe the effects of key abilities on writing performance in…

Decades of research on early care and education have shown that four-year-old children who enroll in prekindergarten (pre-K) programs start kindergarten scoring higher on assessments of academic skills than those who do not. A handful of long-term follow-up studies of pre-K have also found that these programs can have lasting beneficial impacts on…

Teachers in early childhood education (ECE) settings are central to providing children with high-quality experiences that promote both early development and long-term well-being; unfortunately, rates of teacher turnover are high in ECE settings. There are strong theoretical reasons to assume turnover is negatively linked with children's academic…

Executive function and learning behaviour play an important role in children's academic outcomes by helping them maintain attention, work cooperatively, and stay focused, especially for those from lower family socioeconomic status (SES) backgrounds. This study explored whether these learning-related skills were associated with children's…

This study centered on emergent bilingual (EB) students with specific reading comprehension deficits (S-RCD), that is, with poor reading comprehension despite solid word identification skills. The participants were 209 students in Grades 2 to 4, including both EBs and English monolinguals (EMs) with and without S-RCD. Mean comparisons indicated…

This study centered on Dual Language Learners (DLLs) with specific reading comprehension deficits (S-RCD), that is, with poor reading comprehension despite solid word identification skills. The participants were 209 students in Grades 2-4, including both DLLs and English Monolinguals (EMs) with and without S-RCD. Mean comparisons indicated that…

As a spoken word unfolds over time, similar sounding words ("cap" and "cat") compete until one word "wins". Lexical competition becomes more efficient from infancy through adolescence. We examined one potential mechanism underlying this development: lexical inhibition, by which activated candidates suppress…

This study explored the role of growth in the executive components of working memory (WM) on second language (L2) mathematical problem-solving in elementary school children who are emerging bilinguals whose first language (L1) is Spanish. To this end, children (N = 429) in Grades 1, 2, and 3 at Wave 1 were administered a battery of math, reading,…

The present longitudinal study investigated the developmental trajectories of addition, subtraction, and multiplication fluency; their relationships to general cognitive functions; and potential interrelations between reading fluency and growth in arithmetic fluency for different operations. The central prediction was that measures of arithmetic…

The Computer-based Orthographic Processing Assessment (COPA) is a newly developed assessment to measure orthographic processing skills, including rapid perception, access, differentiation, correction, and arrangement. In this study, cognitive diagnostic models were used to test if the dimensionality of the COPA conforms to theoretical expectation,…

This research assessed the impact of combining small-group cognitive reading intervention with a motivational program targeting students' goals, emotions, and self-efficacy beliefs on the reading performance and motivation of third-grade students at risk for reading difficulties (n = 25, M[subscript age] = 8.99, SD = 0.38). Using a…

Research Findings: The aim of the current study was to examine the extent to which the effects of preschool classroom quality on children's mathematics is moderated by executive functioning (EF) during the preschool year. The study sample included 102 children (M age = 53.57 months [SD = 5.42]; 49% male) and one of their parents recruited from 26…

Research Findings: The study examined the relationship between Spanish-speaking DLL children's engagement within the preschool classroom with teachers, peers, and tasks and their school readiness skills compared to monolingual English-speaking peers. Results suggested that DLL children had lower language skills and phonological awareness by the…

This study examined the associations of preschool children's executive function (EF) and learning behaviour (CLB) with their concurrent academic skills and the role of CLB as a mediator for the EF-academic skills link. One hundred seventy-nine children were assessed on EF and math and literacy skills. Parents and teachers completed a questionnaire…

The National Institute for Early Education Research (NIEER) conducted a landscape evaluation of early childhood programs in Indiana (IN) between the spring of 2021 and the summer of 2022. The evaluation included assessments of infant, toddler, and preschooler children's developmental status in multiple domains at two time points to measure growth.…
