Using data from the Early Childhood Longitudinal Study--Kindergarten cohort (ECLS-K), this study aimed to identify body mass index (BMI) trajectories from kindergarten to eighth grade using group-based trajectory modeling (GBTM), examine the relationships between BMI trajectories and adolescents' school achievement (reading and math), determine…

This study examined the cross-lagged relationships between students' autonomous motivations (intrinsic motivation and identified regulations) and approach goals (mastery and performance) in school. The sample included 449 students (52% girls) in Grades 7 and 8 (secondary 1 and 2). Results showed that intrinsic motivation (IM) positively predicted…

The Responses to Educational Disruption Survey (REDS), conducted by the International Association for the Evaluation of Educational Achievement (IEA), studied how teaching and learning were affected by the disruptions caused by COVID-19 and aimed to paint a picture of national responses to the global pandemic. REDS was based on the premise that…

The purpose of this non-experimental, cross-sectional, correlational study was to examine the influence, if any, of mathematical-instructional minutes on academic achievement as measured by the 2014 New Jersey Assessment of Skills and Knowledge (NJ ASK) 6, 7, and 8 mathematics scores. Additionally, the study accounted for other factors that…

This 2-year prospective study aimed to examine the predictive role of students' achievement goals (mastery-approach and performance-avoidance) on socioemotional adjustment in high school by assessing the potential mediating contribution of academic motivations. A total of 407 high school students (46% boys) were surveyed each year in Secondary 2…

Using data from the Early Childhood Longitudinal Study Kindergarten Cohort of 1998 (n = 15,070), this study used propensity scores to examine the short- and long-term academic and psychosocial benefits of preschool education for a diverse sample of middle-class children. Compared with children who attended informal care at age 4, preschool…

Gaps in educational achievement between high- and low-income children are growing. Administrative data sets maintained by states and districts lack information about income but do indicate whether a student is eligible for subsidized school meals. We leverage the longitudinal structure of these data sets to develop a new measure of economic…

The present study used multiple regression analyses to examine the relationships between fifth-grade social skills and eighth-grade academic achievement. Data were drawn from the Early Childhood Longitudinal Study-Kindergarten Class of 1998-1999 (ECLS-K). Results indicated no relationship between positive or negative social behavior in fifth grade…

Programme for International Student Assessment data from 29 countries was used to measure immigrant school gaps (differences in scores between immigrants and natives) in relation to various potentially correlated factors. Results show that negative gaps are concentrated in the European Union; in the South, they are mainly correlated with school…

For a sustainable world, it is very important for students to develop positive environmental attitudes and to have awareness of energy use. The study aims to investigate the effect of web assisted instruction with emotional intelligence content on 8th grade students' emotional intelligence, attitudes towards environment and energy saving, academic…

The present paper (1) examined variables, which could predict traditional bullying, cyberbullying, traditional victimization and cybervictimization and (2) looked at persons to examine whether academic, socio-emotional and demographic characteristics differed between traditional, cyber and mixed bullies, victims and bully-victims. A sample of…

Recently, researchers have begun to employ rigorous statistical methods and developmentally-informed theories to evaluate outcomes for students retained in non-kindergarten early elementary school. However, the majority of this research focuses on academic outcomes. Gaps remain regarding retention's effects on psychosocial outcomes important to…

We examined the age of onset, over-time dynamics, and mechanisms underlying science achievement gaps in U.S. elementary and middle schools. To do so, we estimated multilevel growth models that included as predictors children's own general knowledge, reading and mathematics achievement, behavioral self-regulation, sociodemographics, other child-…

Using Hofstede's culture dimensions and World Values Survey (WVS) dimensions, the study uses a series of multiple regressions to explore the relationship among national culture, creativity as measured by patents, economic productivity as measured by gross domestic product per capita, and student achievement as measured by Trends in International…
