Background: The working memory (WM) system is recognized as a crucial cognitive function that underpins the acquisition of new knowledge and the development of foundational skills during childhood. Children's early literacy and numeracy skills lay the foundation for future academic success in reading and mathematics. While previous research has…

A short form of the 60-item computer-based orthographic processing assessment (long-form COPA or COPA-LF) was developed. The COPA-LF consists of five skills, including rapid perception, access, differentiation, correction, and arrangement. Thirty items from the COPA-LF were selected for the short-form COPA (COPA-SF) based on cognitive diagnostic…

The Hearts and Flowers (H&F) task is a computerized executive functioning (EF) assessment that has been used to measure EF from early childhood to adulthood. It provides data on accuracy and reaction time (RT) across three different task blocks (hearts, flowers, and mixed). However, there is a lack of consensus in the field on how to score the…

The concept, development and assessment of computational thinking have increasingly become the focus of research in recent years. Most of this type of research focuses on older children or adults. Preschool age is a sensitive period when many skills develop intensively, so the development of computational thinking skills can already begin at this…

Research indicates that the achievement gap in reading between typical and dyslexic readers is already evident in first grade and persists through adolescence. However, it is not known whether this reading gap persists into adult life. In this report we use an epidemiologic sample of 312 children (typical readers = 246; dyslexic readers = 66),…

The ability to effectively identify students for advanced learning opportunities has been an ongoing issue within the field of gifted education. Common criteria to guide the design and evaluation of identification systems has been essentially non-existent. In this article we provide a practical guide for evaluating and reflecting on the…

Working memory is an often studied and important psychological construct. The growth of working memory capacity (WMC) in childhood is described as linear. Average adult WMC is estimated as either four or five "chunks." Using latent curve models of data from a measure of digit span backward that was administered longitudinally to a large…

With the increasing importance of Computational Thinking (CT) at all levels of education, it is essential to have valid and reliable assessments. Currently, there is a lack of such assessments in upper primary school. That is why we present the development and validation of the competent CT test (cCTt), an unplugged CT test targeting 7-9 year-old…

Courses in teacher training programmes, especially science method courses, play a major role in the development of beliefs. Because children's science learning starts in preschool years, it is critical to investigate early childhood teachers' beliefs about scientists and science teaching. The purpose of this study was to describe, document, and…

We report on an innovative computer-adaptive assessment, the Comprehensive Research-based Early Math Ability Test (CREMAT), using the case of 1st- and 2nd-graders' understanding of geometric measurement. CREMAT was developed with multiple aims in mind, including: (1) be administered with a reasonable number of items, (2) identify the level(s) of…

Observational studies comparing child outcomes in early care and education classrooms of differing quality are often confounded by between-child differences. A within-child design, tracking children across contexts, can identify the effects of quality with less confounding. An analysis of Australian children (N = 1128, mean age 5 years, 48%…

The early elementary years are foundational for future academic achievement, and, as the number of Latino students in U.S. schools continues to rise, more attention has been given to the academic performance of these young learners. Yet little is known about the cognitive skills, such as executive function (EF), that may underlie Latinos' academic…

This study explores the influence of kindergarten care on the social and cognitive development of Saudi Arabian and international students in early childhood education in Saudi Arabia. A mixed-methods approach assessed the development of 302 children, aged between 5 years and 11 months to 7 years, and their mothers in Saudi Arabia's Eastern…

Research Findings: Greater self-regulation has been identified as a protective factor for low-income children's academic achievement. However, we know less about the long-term protective nature of specific aspects of self-regulation. Data were drawn from predominantly African American and Latino children in low-income communities in Boston,…

Children's Approaches to Learning (AtL) represents how children seek learning opportunities in their classrooms. It can include children's persistence, attention, and initiative. It has often been studied using a composite of a teacher-rated scale. However, person-centered approaches may account for heterogeneity in children's learning approaches,…
