Using meta-analytic techniques, we examined systematically the evidence linking peer social acceptance to academic achievement. Based on 72 studies that yielded 157 effect sizes, we analyzed relations between social acceptance and academic outcomes (e.g., academic grades, test scores), including the extent to which relations were moderated by sex,…

Theoretical models of reading comprehension have consistently highlighted the importance of inference generation in the meaning-making process. Additionally, previous research has indicated that instruction in making inferences is effective at improving inference ability and general reading comprehension. In this meta-analysis, we aimed to further…

This review examined the relations between grit and academic achievement based on a meta-analysis of 137 studies yielding 156 dependent samples (N = 285,331). Using the robust variance estimation, we found that the correlations of overall grit level with academic achievement were generally weak to moderate (weighted r = 0.19). The correlation of…

In this review we examine the evidence regarding self-determination theory within the school physical education context. We applied a multilevel structural equation modeling approach to meta-analyze data from a systematic review that identified 265 relevant studies. In line with theory, autonomous motivation was positively correlated with adaptive…

Principal strain and burnout is a major issue in desperate need of further investigation and solutions. Deepening our understanding of emotional exhaustion, the central dimension of burnout, would greatly further this pursuit. Using a large, longitudinal, representative sample of Australian school principals, the present study decomposed emotional…

This meta-analysis synthesized the available empirical evidence on the impact of interventions on the development and enhancement of mathematical word problem solving skills for K-12 students with learning disabilities (LD) and those with mathematics difficulties (MD). A total of 33 studies met inclusion criteria for this meta-analysis. After…

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…

This study utilized multilevel modeling to examine the student characteristics (gender and age) and school factors (private vs. public school, urban vs. rural school, socioeconomic status, curricular organization, resources, activities, and equipment) associated with individual and between-school differences in the verbal, numerical, and figural…

The contributions of domain-general abilities and domain-specific knowledge to subsequent mathematics achievement were longitudinally assessed (n = 167) through 8th grade. First grade intelligence and working memory and prior grade reading achievement indexed domain-general effects, and domain-specific effects were indexed by prior grade…

This study investigated the effectiveness of the KiVa Antibullying Program in two samples of students, one from Grades 1-3 (7-9 years old, N = 6,927) and the other from Grades 7-9 (13-15 years old, N = 16, 503). The Grades 1-3 students were located in 74 schools and Grades 7-9 students in 73 schools that were randomly assigned to intervention and…

This investigation's aims were to map prevalence, normative trends, and patterns of continuity or change in school-based peer victimization throughout formal schooling (i.e., Grades K-12), and determine whether specific victimization patterns (i.e., differential trajectories) were associated with children's academic performance. A sample of 383…

The present study investigated (a) how a latent profile analysis based on representative data of N = 74,868 4th graders from 17 European countries would cluster the students on the basis of their reading, mathematics, and science achievement test scores; (b) whether there would be gender differences at various competency levels, especially among…

A large body of research has demonstrated a big-fish--little-pond effect (BFLPE) by showing that equally able students have lower academic self-concepts in high-ability schools than in low-ability schools. Although the BFLPE generalizes across many countries, it varies significantly between countries. The reasons for this variation are still…

Using data from a 40-year longitudinal study, the authors examined 3 related hypotheses about the effects of grade skipping on future educational and occupational outcomes in science, technology, engineering, and mathematics (STEM). From a combined sample of 3,467 mathematically precocious students (top 1%), a combination of exact and propensity…

Two studies were designed to extend Butler's (2007) model and measure of achievement goals for teaching, to recognize that teaching is an interpersonal endeavor, not just personal endeavor. In Study 1, results from 530 teachers in Israel confirmed the predicted 5-factor model comprising relational goals, whereby teachers aspire to create close and…
