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…

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. Work on remembered success has primarily been done with adults. We assessed (in a preregistered study)…

Relative age effects (RAEs), where older children within an age-based group have better academic, sporting, self-concept and mental health outcomes than their younger peers, have been demonstrated in multiple countries. Australian research has found self-concept and Attention Deficit Hyperactivity Disorder RAEs, but academic RAEs have not been…

Gender stereotypes about science, technology, engineering, and math (STEM) are salient for children and adolescents and contribute to achievement-related disparities and inequalities in STEM participation. However, few studies have used a longitudinal design to examine changes in gender stereotypes across a range of STEM fields. In a large,…

This study aimed to extend the literature by examining how bystander intervention (i.e. when a witness to a bullying episodes does something to address the situation) varies with respect to the type of bystander intervention (i.e. direct intervention, emotional intervention, involving an adult, ignore) across victim status (friend, unknown),…

Perceived life satisfaction during the period of childhood and adolescence can be considered a reliable measure of psychological and emotional growth of children and adolescents. The current study aimed to investigate age differences related to social support provided to students (by teachers, classmates, parents and close friends), and its…

There is a lack of research on students' conceptions of giftedness and intelligence, despite recognition of their influence on real-life factors such as achievement and motivation. This paper presents a cross-sectional mixed methods study that investigated Finnish students' (age 6-16 years; N = 1282) implicit conceptions of giftedness and…

Prior research links need for approval (NFA; the extent to which self-worth is contingent on peer approval or disapproval) to critical developmental outcomes, but little is known about how NFA develops over time or within social contexts. To address this gap, the present study used a sophisticated analytic approach (autoregressive latent…

Engaging key stakeholders, including students into the process of school-based physical activity (PA) intervention planning is considered important. The present study was part of the preparatory phase of the Estonian Schools in Motion pilot programme and aimed to examine students' perspective of PA opportunities in the classroom. Based on 17 focus…

We use nearly 430 million standardized test scores, including test scores from more than 6,500 rural school districts, to describe educational opportunity in rural America. Although we find modest differences in outcomes between rural and nonrural students overall, these disparities are larger for specific socioeconomic, racial-ethnic, and…

This research investigated whether delayed school entry was associated with higher achievement in national tests of reading and numeracy in Grades 3, 5, 7, and 9 (n = 2,823). Delayed entry was related to advantages in reading (0.14 SD) and numeracy (0.08 SD) at Grade 3, although little variance was explained (1%-2%). This slight advantage…

Growth in working memory capacity, the number of items kept active in mind, is thought to be an important aspect of childhood cognitive development. Here, we focused on participants' awareness of the contents of their working memory, or "meta-working memory," which seems important because people can put cognitive abilities to best use…

One hundred four students aged 8 to 16 worked on one Fermi problem involving estimating the number of people that can fit in their school playground. We present a qualitative analysis of the different mathematical models developed by the students. The analysis of the students' written productions is based on the identification of the model of…
