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,…

There is evidence of a relation between the approximate number system (ANS) and later mathematics achievement. Researchers have proposed various mediators of this relation, including executive functioning (EF), numeral knowledge, and mathematical language. The goal of the present study was to determine which factors mediate the relation between…

Digital badges have long been assumed to possess motivational qualities that could encourage learners to engage with learning content. However, prior studies have found the effects of badges to be complex, differing by learner, type of badge, and potentially other factors. Qualitative reports suggest that individuals' perceptions of digital badges…

Despite the recognized importance of addressing belief bias in critical thinking, little is known about the neural activity underlying belief-bias reasoning and its connection to critical thinking. The study utilized event-related potentials (ERPs) to examine the neural responses during belief-bias reasoning and explored the extent to which these…

Decades of research suggest that learning styles, or the belief that people learn better when they receive instruction in their dominant way of learning, may be one of the most pervasive myths about cognition. Nonetheless, little is known about what it means to believe in learning styles. The present investigation uses one theoretical…

Fraction arithmetic facility is fundamental to learning more advanced math topics. However, attaining the ability to add and subtract fractions is hard for many students. The present longitudinal study examined students' growth on simple addition and subtraction word problems between fourth and sixth grades (N = 536). Latent class growth analyses…

Achievement emotions have received increasing attention in research on adolescence and young adulthood, but little is known about these emotions in the early years of schooling. Studies addressing the development of different achievement emotions and their linkages with achievement during these years are largely lacking. The present longitudinal…

Poorer language ability has been shown to predict the development of externalizing behavior problems such as aggression and conduct problems. However, the developmental process that links poorer language ability to externalizing problems is unclear. The present study examined (a) whether within-child changes in language ability predict…

Self-handicapping is a maladaptive strategy that students employ to protect their self-image when they fear or anticipate academic failure. Instead of increasing their effort, students may harm their chances of success by procrastinating, strategically withdrawing effort, or engaging in destructive behaviors like drug abuse, so that potential…

The present study longitudinally investigated proportional reasoning abilities in early elementary school before the start of its instruction. Three aims were put forward: (a) distinguishing the different developmental states in young children's understanding of missing-value proportional situations, (b) investigating how children transition…

A great deal of bullying behavior takes place at school, however, existing literature has predominantly focused on individual characteristics of children associated with bullying with less attention on school-level factors. The current study, comprising 23,215 children (51% boys) recruited from Year 4 or Year 5 (M = 9.06 years, SD = 0.56 years)…

Inference making is fundamental to the construction of a coherent mental model of a text. We examined how vocabulary and verbal working memory relate to inference development concurrently and longitudinally in 4- to 9-year-olds. Four hundred and twenty prekindergartners completed oral assessments of inference making, vocabulary breadth, vocabulary…

Teacher-student relationships are an important part of students' interpersonal context at school that impacts their academic development. This study extended prior research into teacher-student relationships by exploring the relative balance of negative and positive teacher-student relationships in high school students' academic lives (in each of…

Although peer victimization in school mainly takes place between children in the same classroom or grade and bullying is generally seen as a group process, little is known about how stability and change in classroom composition affect peer victimization. Hence, this study addressed the following questions: (a) Are newcomers in the classroom more…

Immigrant and refugee children and adolescents form a growing socially, culturally, and economically diverse group with the potential for wide-ranging adaptation outcomes. The goal of the study was to examine whether developmental competencies (social-emotional and academic) and sociodemographic disparities (e.g., SES and migration class)…
