Purpose: This study investigated the etiology of late language emergence (LLE) in 24-month-old twins, considering possible twinning, zygosity, gender, and heritability effects for vocabulary and grammar phenotypes. Method: A population-based sample of 473 twin pairs participated. Multilevel modeling estimated means and variances of vocabulary and…

Applications of multilevel models to continuous outcomes nearly always assume constant residual variance and constant random effects variances and covariances. However, modeling heterogeneity of variance can prove a useful indicator of model misspecification, and in some educational and behavioral studies, it may even be of direct substantive…

Identifying sources of variation has been used extensively in educational research as a tool to identify potential drives of variances in student achievement. However, prior research predominantly relied on findings from national- or international-level data, and thus their conclusions remain very broad-based. This study contributes new insight by…

This article examines if and how characteristics of appraisal systems used for secondary school teachers affect job satisfaction. Using multilevel analyses on data of 3 473 teachers in Flanders (Belgium), we found that appraisals with a developmental purpose and appraisals perceived as being a fair judgement, both have a positive impact on job…

Valid and reliable measurement of teaching is essential to evaluating and improving teacher effectiveness and advancing large-scale policy-relevant research in education (Raudenbush & Sadoff, 2008). One increasingly common component of teaching evaluations is the direct observation of teachers in their classrooms. Classroom observations have…

Background and Aims. This study used Ecological Momentary Assessment (EMA) in mother-child dyads to examine the day-level associations of stress and eating. Method. Mothers and their 8- to 12-year-old children (N = 167 dyads) completed between three (weekday) and eight (weekend) EMA survey prompts per day at random nonschool times across 8 days.…

Hong Kong underwent tremendous changes after the transfer of its sovereignty to China in 1997. This study attempts to explore the changing role of schools in preparing students for future democratic citizenship in the post-colonial era. Different researchers have postulated that schools play a crucial role in the political socialization process in…

Previous research on curriculum-based measurement of oral reading fluency (CBM ORF) found high levels of variability around the estimates of students' fluency; however, little research has studied the issue of variability specifically with well-designed passage sets and a sample of students who scored below benchmark for the purpose of progress…

This study extends previous research investigating the effects of state-wide exit exams by studying the change from a class-based to a state-wide exit exam system over 5 years, using multilevel analyses and examining mediating effects of teachers' practices on students' motivational orientations. In this multi-cohort study, we analyzed in…

Student affairs practitioners and scholars are paying greater attention to issues of religion and spirituality on college campuses. The present study explores the link between campus religious/worldview climate and overall student engagement within a longitudinal sample of 14,517 undergraduates at 134 colleges. When controlling for various student…

Purpose: To examine the extent to which neighborhood disadvantage accounts for variation in blood pressure. Methods: Demographic, biometric, and self-reported data from 19,261 health screenings were used. Addresses of participants were geocoded and located within census block groups (n = 14,510, 75.3%). Three hierarchical linear models were…

The relationships between reasoning and school achievement were studied taking into account the multilevel nature (school- and class-levels) of the data. We gathered data from 51 classes at seven schools in metropolitan and Eastern Finland (N = 769, 395 males, 15-year-old students). To study scientific reasoning, we used a modified version of…

Qualitative research has identified college choice organizational habitus (CCOH) as an important mediating mechanism through which high school socioeconomic composition influences students' college choice, perpetuating social reproduction and educational inequity. This study examines the mediation effects of 2 general forms of CCOH: normative…

In Chile, the influence of the socioeconomic make-up of classrooms on achievement has been extensively studied in mathematics and language, but less in currently important non-traditional subjects such as civic knowledge. This paper analyses the effects of the socioeconomic composition of classrooms on students' civic knowledge achievement in…

When students chatter in class it can be disruptive, but could that chatter also have some redeeming qualities? We asked students to keep track of their social interactions in a particular class. On days when students had more social interactions than usual, they reported a greater sense of belonging, which was, in turn, related to greater class…
