In this meta-analysis of 54 longitudinal studies with over 58,000 students in kindergarten through 12th grade, we examined the predictive nature of early numeracy measured at or before the first year of formal schooling in relation to later mathematics. Results showed that early numeracy significantly predicted mathematics measured after 6 months…

Working memory is an essential mechanism in the cognitive learning process. However, its definitions and mechanisms remain a topic of debate. Miller-Cotto and Byrnes ("Journal of Educational Psychology," "112"(5), 1074-1084, 2020) reported a comparison of three models of working memory to determine which best accounted for data…

The purpose of this qualitative research study is to portray the complex language practices of multilingual children when learning mathematics. To do so, I draw on data collected as part of a three-year research study that was designed to understand the relationship between young children's language use and mathematics learning, focusing on…

Background: Observation Studies, Unmeasured Confounding, and Sensitivity Analysis: An important part of educational research is identifying important, potentially causal, factors that influence children's learning from observational studies. However, it is well-known that discovering such factors from observational studies can be biased due to…

Background: Children with developmental language disorders (DLDs) often struggle with classroom behaviour. No study has examined whether positive teacher-child relationships may act as a protective factor for children with DLDs in that these serve to enhance children's important classroom-learning behaviours. Aims: To examine the association…

When identifying parental socialization processes influencing children's reading achievement, building self-regulation is a potential underlying mechanism. Yet socialization (i.e., warmth, stress) of self-regulation may vary based on the sociocultural context of ethnic minority families. Using the ECLS-K: 2011 (N = 17,020; M[subscript Age] = 73.43…

Publicly funded center-based preschool programs were designed to enhance low-income children's early cognitive and social-emotional skills in preparation for kindergarten. In the U.S., the federal Head Start program and state-funded public school-based pre-kindergarten (pre-k) programs are the two primary center-based settings in which low-income…

Background: There is an increased focus on randomized trials for proximal behavioral outcomes in early childhood research. However, planning sample sizes for such designs requires extant information on the size of effect, variance decomposition, and effectiveness of covariates. Objectives: The purpose of this article is to employ a recent large…

First-time kindergartners who demonstrated positive approaches to learning behaviors more frequently in the fall of kindergarten tended to make greater gains in reading, mathematics, and science between kindergarten and second grade. For each additional point in students' fall kindergarten approaches to learning score, average gains from…

Recent studies focused on the influence of orthographic processing on reading and spelling performance. It was found that orthographic processing is an independent predictor of reading and spelling performance in different languages and children of different ages. This study investigated sensitivity to orthographic regularities in German-speaking…

This article reports on the study of differential change trajectories for early childhood approaches to learning. A large sample (N = 2,152) of Head Start children was followed through prekindergarten, kindergarten, and first grade. Classroom learning behaviors were assessed by teachers through the Preschool Learning Behaviors Scale twice in Head…

This study aims to explain how the practice of two languages (French and Creole) in French overseas departments affects the first educational competencies acquired by children. The students' performance in both languages was investigated at the beginning of kindergarten, and their reading capacities were measured at the end of Grade 1. The data…

Using a cluster randomized trial design, we evaluated the persistence of effects of a research-based model for scaling up educational interventions. The model was implemented in 42 schools in two city districts serving low-resource communities, randomly assigned to three conditions. In pre-kindergarten, the two experimental interventions were…

Grade 1 literacy skills of twin children in Australia (New South Wales) and the United States (Colorado) were explored in a genetically sensitive design (N = 319 pairs). Analyses indicated strong genetic influence on word and nonword identification, reading comprehension, and spelling. Rapid naming showed more modest, though reliable, genetic…

Research on learning disabilities (LD) depends upon a conceptual framework that specifies what it should explain, what kinds of data are needed, and how these data are to be arranged in order to provide a meaningful explanation. An argument is made that LD are no different in this respect than any other form of human illness. In this article, a…
