A large literature documents that there are significant academic and non-academic differences between the youngest and oldest students in a school cohort. This paper investigates if being the youngest in a cohort has any impact on an individual's propensity to commit crime by utilizing a data set that contains over 4 million arrest records…

In this paper, the multidigit arithmetic-related strategy adaptivity, strategy flexibility and solution accuracy of Danish compulsory school students is examined. Participants, 749 grade three, 731 grade six and 818 grade eight, were drawn from twenty demographically different schools. Drawing on a tri-phase assessment tool, each student completed…

This study examined how adolescents' emotions in mathematics develop over time. Growth curve modeling was applied to longitudinal data collected annually from 2002 to 2006 (Grades 5-9; N = 3425 German adolescents; M[subscript age] = 11.7, 15.6 years at the first and last waves, respectively; 50.0% female). Results indicated that enjoyment and…

The "remembered success effect" (Finn, 2010) refers to the finding that challenging academic tasks that start or end with extra opportunities for success are preferred to challenging tasks that do not include these opportunities.

The current study was conducted to investigate the relationship between math anxiety and math achievement, highlighting differences in motivation based on age, and the mediating effects of task persistence as well as aspects of the expectancy-value theory. The students in the study (grade five N = 335, grade eight N = 251) were from Estonian…

To investigate students' interest in physics, this study explores the impact of a brief teaching intervention on the increase of interest. The intervention focused on modern physics, specifically exploring Einstein's theory of gravity and the dual nature of light. A total of 325 Greek students participated in the survey, comprising 83 students in…

We investigated how the sequence of presenting social media sources in an unsupervised inductive learning setting supports the acquisition of source evaluation skills in two different age groups. Participants were 63 upper and 59 lower secondary students. They had to identify characteristics of trustworthiness while studying sources labeled as…

Bullying is a considerable problem among school students, and school-wide positive behaviour support interventions are regarded as helpful in addressing it. One approach is the CATZ Cross-age Teaching Zone anti-bullying intervention. The present study assessed the social validity of the CATZ anti-bullying intervention among a sample of…

Previous research has evidenced a strong positive relationship between leisure print reading habits and reading comprehension across the lifespan. The rapid evolution of new forms of leisure digital reading could modify such a relationship. This meta-analysis extends previous research by analyzing the relationship between leisure digital reading…

Developing algebraic thinking is a key factor in learning mathematics. Despite its importance, many students still struggle with algebraic concepts. This research investigates students' achievements in algebraic thinking using Demetriou's test across 7th (approximately 12-13 years old), 8th (approximately 13-14 years old), and 9th (approximately…
