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…

We investigated the effect of cognitive training of executive functions on children's cognitive outcomes. To address this issue, a systematic meta-analysis of published research articles on cognitive training interventions was performed considering children's age, training duration, -procedure, and -technology in moderator analyses. The results (N…

Scientific modeling (SM) is a core practice of science and an important component of scientific literacy. Supporting students in developing the competence to construct, use, evaluate, and revise models is hence of particular relevance. While research has shown that spatial visualization (SV), a core component of spatial ability, is correlated with…

Formal climate education without consideration of the ocean is incomplete. The effectiveness of a new climate lesson for youth that includes the ocean-climate nexus was examined by delivering the lesson to nine classes situated in separate British Columbia, Canada public schools and assessing the students' understanding of basic climate concepts…

The fact that the passion for digital gaming, which brings a sedentary lifestyle, replaces traditional games requiring exercise and physical education also has a negative impact on the health of children and adolescents. In this study, it was aimed to examine and evaluate high school students' attitudes towards digital gaming and sports by certain…

The aim of the present study was to gain an insight into French young people's conceptual development regarding the greenhouse effect. Because this effect cannot be directly manipulated, we can assume that its conceptualization is mainly shaped through the sharing of information. Eighty French students from Grade Seven through to adulthood…

The relative age effect (RAE) refers to that children born early in their year of birth show higher performance compared to children born late in the same cohort. The present study evaluated whether RAE exists within non-competitive physical education (PE) attainments, change in RAE magnitude with age, and possible gender differences. The results…

Past research has investigated the development of stereotypes surrounding race and gender in children; however, there is a lack of literature examining the development of children's stereotypes of older adults. In this study, 163 children from four grades: first (n = 44), fourth (n = 49), fifth (n = 35), and eighth (n = 35) completed a new…

This paper is a follow-up on our 2017 study of the effect of Age of Onset of learning English (AO) on the academic performance of University of Papua New Guinea (UPNG) students in the School of Humanities and Social Sciences (SHSS). It investigates the relationship between three factors in the students' Early Language Education {Age of Onset of…

This study contributes to the investigation of the variability of the schooling effect on cognitive development between educational systems and its underlying factors, by focusing on 3 cases differing in the characteristics assumed to affect the magnitude of the schooling effect (the quality of the schooling and students' mean ability to benefit…

Complex problem solving (CPS) as a cross-curricular competence has recently attracted more attention in educational psychology as indicated by its implementation in international educational large-scale assessments such as the Programme for International Student Assessment. However, research on the development of CPS is scarce, and the few…

When do children develop the ability to imagine their future lives in terms of a coherent prospective life story? We investigated whether this ability develops in parallel with the ability to construct a life story for the past and narratives about single autobiographical events in the past and future. Four groups of school children aged 9 to 15…

A socio-psychological analytical framework will be adopted to illuminate the relation between socioeconomic status and academic achievement. The framework puts the emphasis to incorporate micro familial factors into macro factor of the tracking system. Initially, children of the poor families always lack major prerequisite: diminution of cognitive…

Dual-process theories have been proposed to explain normative and heuristic responses to reasoning and decision-making problems. Standard unitary and dual-process theories predict that normative responses should increase with age. However, research has focused recently on exceptions to this standard pattern, including developmental increases in…

According to Klahr's (2000, 2005; Klahr & Dunbar, 1988) Scientific Discovery as Dual Search model, inquiry processes require three cognitive components: hypothesis generation, experimentation, and evidence evaluation. The aim of the present study was to investigate (a) when the ability to evaluate perfect covariation, imperfect covariation,…
