The natural development of static lower limb varus/valgus alignments during early childhood is well understood. However, our understanding of dynamic lower limb frontal plane alignments is limited, and we lack normative descriptions of this phenomenon for both boys and girls. This study investigated dynamic lower limb alignment during…

This longitudinal study examined age- and gender-related differences in autobiographical memory about the COVID-19 pandemic lockdowns and whether the content of these memories predicted psychological adjustment over time. A sample of 247 students (M[subscript age] = 11.94, range 8-16 years, 51.4% female, 85.4% White) was recruited from public and…

Motivated by a curriculum privileging number-based strategies but national tests highlighting students' reliance on standard algorithms, this study analyses 2,216 Danish Grade 3, 6 and 8 students' solutions to various multidigit arithmetic tasks, each designed to elicit shortcut strategies, against background variables including sex, ethnicity and…

This study examines emotional well-being variations among students (n = 13,398) across 5 countries during the COVID-19 pandemic. Secondary analysis is conducted using data from the "Responses to Educational Disruption Survey" (REDS), which focused on the pandemic experiences, including well-being, of 8th-grade students. The study…

This study examined gender differences in reading behavior of 2652 Danish 5th-grade students (age 10-12 years, girls 51%, 14% immigrant background) observed for 218 days in 2019/2020, using data from a popular reading app. Reading behavior was operationalized as time spent reading. Analyses of timing of reading behavior and models of day-to-day…

This study examined the variable relationships among four factors and school liking, controlling for gender, grade level, and maternal educational level. Repeated cross-sectional survey data from Danish public schools were analyzed across three measurement points (2015, 2017, and 2019) using multigroup structural equation modeling. Responses of…

Digital transformations within educational systems are recurrently justified by their promise to enhance learning activities and outcomes. We examine this claim in a study of pupils' perception and experiences with computer-based adaptive tests in higher classes in Danish public primary schools. The study relies on survey and interview data and…

The persistent gender gap in science, technology, engineering, and mathematics (STEM) is often attributed to differences in students' confidence in their own academic abilities (i.e. self-efficacy). Yet, the role of self-efficacy in mediating gender differences in STEM attrition is unclear. To address this issue, we analyse administrative register…

Background: There is a need to systematically compare and contrast mortality predictors and disparities in people with intellectual disabilities (ID) for global prevention strategy development. Method: Bibliographic databases and grey literature were searched using systematic review methodology and the machine learning tool "Abstrackr."…

In large-scale assessments, performance differences across different groups are regularly found. These group differences (e.g., gender differences) are often relevant for educational policy decisions and measures. However, the formation of these group differences usually remains unclear. We propose an approach for investigating this formation by…

Strategy use in single-digit addition is an indicator of young children's numeracy comprehension. We investigated Danish primary students' use of strategies in single-digit addition with interview-based assessment of how they solved 36 specific single-digit addition problems, categorised as either 'error', 'counting', 'direct retrieval' or…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

Smith-Magenis syndrome (SMS) is a genetic syndrome most often caused by a deletion on chromosome 17 or more rarely by a mutation in the retinoic acid-induced 1 gene. The aim of this study was to investigate the Developmental Behavior Checklist (DBC) profile of persons with SMS and the associations between behavioural and emotional problems, age,…

Objective: This study investigated active recess as an innovative approach to improving physical activity levels in European primary schools, addressing the need to counteract sedentary behaviour and enhance health in students. Method and Design: Using rapid reviewing, the article summarises empirical evidence from a variety of sources, including…

The pluralisation of European societies has produced national and cultural diversification, increasing the need for communication and understanding to support recognition, equality, justice, self-determination and identification with others. This paper responds to the social and political challenges accompanying immigration by focusing on gender…
