We conducted three preregistered studies using the Organization for Economic Co-operation and Development Programme for International Student Assessment (PISA) data to provide a worldwide estimation of the standardized test gap between students from lower and higher social classes. We investigated: (a) the degree to which academic anxiety…

Effective collaborative problem solving comprises cognitive dimensions, in which men tend to outperform women, and social dimensions in which women tend to outperform men. We extend research on between-country differences in gender gaps by considering collaborative problem solving and its association with two indicators of societal-level gender…

"Grit" is defined as passion and perseverance for achieving long-term goals and consists of two proposed subcomponents: consistency of interests and perseverance of effort. It has become a much-discussed construct even though research on its underlying factor structure has produced inconclusive results. Furthermore, grit as measured by…

The home numeracy environment (HNE) is an essential factor to explain family engagement in relation to numeracy. Research in this field has mostly focused on English-speaking families and has not taken into consideration cultural differences that contextualize the home environment. Measuring HNE in more ethnically diverse samples might counter…

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…

Many primary school students have difficulties understanding mathematical equivalence with considerably poorer performance in some countries than in others. However, students' formal understanding of equivalence has significant and long-lasting effects, as it predicts arithmetic and algebra achievement throughout school years. Currently, little is…

Extensive support for the seemingly paradoxical negative effects of school- and class-average achievement on academic self-concept (ASC)-the big-fish-little-pond effect (BFLPE)--is based largely on secondary students in Western countries or on cross-cultural Program for International Student Assessment studies. There is little research testing the…

Classmates can influence a student's academic achievement through immediate interactions (e.g., academic help, positive attitudes toward reading) or by sharing tangible or intangible family resources (books, stories of foreign travel). Multilevel analysis of 141,019 fourth-grade students' reading achievements in 33 countries showed that…

In the past 40 years, the proportion of women in science courses and careers has dramatically increased in some nations but not in others. Our research investigated how national differences in women's science participation related to gender-science stereotypes that associate science with men more than women. Data from ~350,000 participants in 66…

Chinese classrooms present an intriguing paradox to the claim of self-determination theory that autonomy facilitates learning. Chinese teachers appear to be controlling, but Chinese students do not have poor academic performance in international comparisons. The present study addressed this paradox by examining the cultural differences in…

A classic distinction in the literature on achievement and motivation is between fear of failure and success orientations. From the perspective of self-worth theory, these motives are not bipolar constructs but dimensions that interact in ways that make some students particularly vulnerable to underachievement and disengagement from school. The…

Although there is increasing awareness of the overrepresentation of ethic minority students--particularly Black students--in disciplinary actions, the extant research has rarely empirically examined potential factors that may contribute to these disparities. The current study used a multilevel modeling approach to examine factors at the child…

Mexican-American and Anglo-American children from a semirural low-income elementary school were tested for competition, individualism, field independence, and school achievement. The Mexican-American children were found to be more prosocial and less competitive, but these factors were not necessarily related to lower school achievement. (GDC)

Peer preferences and perceptions of 258 African-American and 401 White third through fifth graders (313 males and 346 females) attending either majority White or majority African-American classrooms were studied. Racial minority status is associated with peer rejection of girls but not boys. Results support the subjective culture hypothesis. (SLD)

Given the increasingly culturally diverse composition of students in American classrooms, understanding the nature of cultural differences is necessary to generate effective instructional interventions. This study examines the individual differences in epistemological beliefs, ways of knowing, study strategies, and academic performance among…
