This study uses data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K), to examine the texts assigned to eighth-grade students. By comparing student demographic information from the ECLS-K with demographic information from the texts, we examine adjustment of assignments to match students' backgrounds. In…

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 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…

Scholars have differentiated other-oriented (OO) purpose (i.e., a personally meaningful life aim intended to contribute to the world beyond the self) and self-oriented (SO) purpose (i.e., a personally meaningful life aim without intention to contribute beyond the self). OO purpose is associated with adolescent thriving, yet little is known about…

The purpose of this study was to explore the relationship between eighth-grade violinists' pitch perception and instrument tuning skill. The perceptual task was a researcher-developed computer-based Violin Tuning Perception Test. The instrument tuning task involved tuning two violins, one mistuned flat and the other mistuned sharp. Participants (N…

Given their significance to school violence, this study quantifies the association between bullying victimization and perceptions of safety separately for victimization where the type is not specified versus victimization that is physical in nature. Generalized liner mixed modeling was employed with 5,138 sixth- to eighth-grade students in 24…

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…

The present study used data from the Early Childhood Longitudinal Study--Kindergarten Class of 1998-1999 to examine whether the relationship between first-grade word-reading and reading-comprehension growth through eighth grade was different for language-minority learners (LMs) versus native English-speaking students (NEs). Among high word…

This study examined the relationships between youth and parental sensation-seeking, peer influence, parental monitoring and youth risk involvement in adolescence using structural equation modeling. Beginning in Grade 6, longitudinal data were collected from 543 students over 3 years. Youth sensation-seeking in Grade 6 contributed to risk…

Shy children display wariness in unfamiliar social situations and often experience feelings of social anxiety. This study explored the potential mediating role of cognitive biases in the link between shyness and social anxiety in early adolescence. In particular, we focused on judgments of the probability and cost of negative social situations…

Overexcitabilities and perfectionism are often discussed within the context of gifted education, given that both are observed among gifted individuals.

This study investigates the relationships between Internet addiction and the areas of life satisfaction and positive or negative affects in Turkish adolescents. The research sample comprised 358 students studying in the sixth, seventh and eighth grades at four different middle schools in Canakkale city centre during the 2012-2013 academic year, of…

In large-scale educational surveys, a latent regression model is used to compensate for the shortage of cognitive information. Conventionally, the covariates in the latent regression model are principal components extracted from background data. This operational method has several important disadvantages, such as the handling of missing data and…

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…
