Using a sample of schools testing annually in grades 9-11 with a vertically linked series of assessments, a latent growth curve model is used to model test scores with student intercepts and slopes nested within school. Missed assessments can occur because of student mobility, student dropout, absenteeism, and other reasons. Missing data…

This study tested the theory that an authoritative school climate characterized by disciplinary structure and student support is conducive to positive academic outcomes for middle and high school students. Multilevel multivariate modeling at student and school levels was conducted using school surveys completed by statewide samples of 39,364…

Students' social goals--reasons for engaging in interpersonal relationships with peers-are consequential for students' interactions with their peers at school and for their well-being. Despite the salience of peer relationships during adolescence, research on social goals is generally lacking compared with academic goals, and it is unknown how…

Using multilevel modeling, this study examined how different types of bullying, involving both peers and teachers, relate to psychosomatic health complaints. Data were obtained via the Stockholm School Survey from 41,032 ninth- and eleventh-grade students in the years 2004, 2006, 2008, and 2010. Results showed that students involved in bullying as…

Background: Cluster-randomized experiments that assign intact groups such as schools or school districts to treatment conditions are increasingly common in educational research. Such experiments are inherently multilevel designs whose sensitivity (statistical power and precision of estimates) depends on the variance decomposition across levels.…

Using emergent motivation theory, this study analyzes the relationships between high school students' perceptions of their reading skills, task challenge, and personal control over assigned reading activities and their reading engagement (i.e., interest, enjoyment, and concentration) during science instruction. The study also examines how…
