Mathematical competence in middle childhood predicts socioeconomic status in adulthood. Therefore, it is important to understand the components that constitute mathematical competence from kindergarten to sixth grade. Using an analytical approach, in this article, I identify three components: understanding numbers, understanding mathematical…

This document summarises key findings and recommendations from an analysis of Australian Early Development Census (AEDC) data conducted by the Australian Education Research Organisation (AERO) in 2022. AERO's report marks the first time that the skills considered through the Language and Cognitive Skills (school-based) domain in AEDC have been…

More than half of North Carolina's grade 3 students struggle with reading. The percentage of students scoring below proficient in reading at the end of grade 3 was 55 percent in 2017/18. That percentage has remained largely unchanged, at above 50 percent, since 2013/14, when North Carolina passed its K-3 Read to Achieve literacy act. Read to…

This report summarizes results from the Georgia's Pre-K Longitudinal Study Third-Grade Report. The study followed a representative sample of children (n=1,169) from their pre-k experience (2013-2014) through the third grade (2017-2018). Study components include: (1) Standardized child assessments that measure skills across learning domains. By…

Item response theory (IRT) models are the main psychometric approach for the development, evaluation, and refinement of multi-item instruments and scaling of latent traits, whereas multilevel models are the primary statistical method when considering the dependence between person responses when primary units (e.g., students) are nested within…

Every teacher, principal, and school administrator wants their young students to thrive as they move through the transitional kindergarten and kindergarten years and into the early elementary grades. With the implementation of the Common Core State Standards and the Local Control Funding Formula, school districts have new opportunities to…

In Australia and many other countries, the provision of the healthiest possible start in life for all children has been a priority for government. Evidence to support the importance of the early years for future development has accumulated over the past two decades [1]. Patterns of childhood development predict health, wellbeing, learning and…

This executive summary provides highlights from the full report (published separately) that summarizes analyses of the effects of the Social and Emotional Learning (SEL) program on outcomes of interest over time. Data are analyzed based on school longevity in SEL. [For the full report, see ED626963.]

This executive summary presents results from a study that began in 2013-2014, and involves a longitudinal design to follow a sample of 1,169 children (139 Spanish-speaking DLLs) who attended 199 randomly-selected Georgia's Pre-K classrooms. These findings focus on results from the second year of the study, which included 1,034 of these children…

A valid screening system requires a screener that accurately predicts whether or not students are at risk given their current performance. To understand a screening measure's accuracy, predicted student performance data (i.e., screening data) must be compared with actual performance data. When these sets of data are compared in a setting where…

This article purports to present this Special Issue about Bullying and, at the same time, to introduce the phenomenon of bullying in order to facilitate readers an updated vision about the problem that will be worked from different perspectives by researchers from national and international scope.
