This study examined the impact of COVID-19 on academic "redshirting" in kindergarten, the practice of holding a child back for a year and enrolling them in kindergarten at age 6, using student-level data on all Delaware kindergarten students from fall 2014 through fall 2022. The rate of redshirting declined by 40% in fall 2020, then…

Literacy and numeracy are correlated throughout development, however, our understanding of this relation is limited. We explored the predictors of literacy and numeracy covariance (i.e., shared fluency between literacy and numeracy) in children (N = 1167, girls = 563) in rural Côte d'Ivoire, with specific focus on how developmental timing of…

Grade placement of newcomer immigrants into U.S. High schools continues to challenge many educators. This becomes even more significant when newcomer immigrants come from countries where education systems are different; or in some cases, their educational development is completely disrupted. Also, curriculum analyses have suggested math concepts…

Relative age effects occur when older and younger students are peers in the same classroom. Previous research in this field has shown that older children have higher academic achievement compared to the youngest children in the same grade. This study examined the effects of separating kindergarten students into classes based solely on age. The…

With the development of technology, people's gaming tools and practices have also changed. While games are an activity that people need to have fun, they are also important for their cognitive and affective development. Today, digital games have largely replaced traditional games and become popular among children and young people. This situation…

Segregated schools have not been sufficiently explored and reflected upon. The appearance and facilities of these schools have not yet been mapped in detail, nor how they operate day by day. This article attempts to help fill this knowledge gap through the example of a segregated school in eastern Slovakia attended exclusively by Roma pupils. The…

The purpose of this archival quantitative research study was to investigate the effects of relative age and eligibility for special education through third grade. This study further examined relative age as it related to gender, ethnicity, socioeconomic status, and multilingual learner status on eligibility for special education under the…

Adolescent mental health is a growing concern in the United States. Children who experience mental health issues struggle in the school environment if their needs are not met. Teachers play a critical role in the classroom when identifying students who struggle with mental health issues. The purposes of this convergent, parallel mixed-methods…

There is an increasing interest in the integration of computational thinking (CT) in the K-12 curriculum. By integrating CT into other disciplines, the aim is to equip students with essential skills to navigate domain-specific challenges. This study conducts a systematic review of 108 peer-reviewed scientific papers to analyze in which K-12…

The School Admissions Code ('the Code') requires school admission authorities to provide for the admission of all children in the September following their fourth birthday. This is when children usually start school, but a child does not reach compulsory school age until the "prescribed day" following their fifth birthday (or on their…

Restraints of the age-graded classroom on grade-level organizational structures have been present since the beginning of formal schooling in the United States. Using interpretivist case study methods, this research explored administrators' and teachers' experiences with self-contained and departmentalized classrooms at the elementary level. Data…

The Negative Year in School Effect (NYiSE) claims that grade-relative-to-age influences academic self-concept. Being young for your grade is associated with lower self-concept, whereas being old for your grade is associated with higher self-concept. We extend this research in several ways. First, we aim to improve causal claims for the NYiSE by…

When student achievement is assessed, we seek to elicit a student's maximum performance -- a goal requiring the assumption that the student is fully engaged. Otherwise, to the extent that disengagement occurs, test performance is likely to suffer. Effectively managing test-taking disengagement requires an understanding of the testing conditions…

In the United States, when a child turns five years of age, he or she is eligible to enroll and attend five-year old kindergarten. Parents and caregivers are often tasked with making the decision on whether or not to enroll their child when eligible to attend kindergarten or if the child should be held back another year (redshirted) and attend…
