Informed by two theoretical models of homework effects, we extended a model of homework on mathematics achievement in a large sample of Chinese eighth graders. Our model incorporated six clusters of homework variables -- student background factors, homework characteristics, teacher variables, parent variables, student motivation, and homework…

Current practices for growth mixture modeling emphasize the importance of the proper parameterization and number of classes, but the impact of these decisions on latent class composition and the substantive implications has not been thoroughly addressed. Using measures of behavior from 575 middle school students, we compared the results of several…

We examined the mediating role of students' interpersonal and academically related social goals in linking students' perceptions of teacher and peer personal and academic emotional supports to their classroom behavior (prosocial, social responsibility) in a sample of young adolescents (n = 3,092) from 7 schools from the mid-Atlantic, Midwest, and…

This study examined the development of noncognitive skills in a sample of 4,769 Hispanic/Latino students as they went through middle school and the first year of high school using ACT Engage 6-9, an assessment designed to predict student outcomes by measuring students' behaviors and psychosocial attributes. The scales of Academic Discipline,…

Contending that justice experiences at school transmit messages about the wider society and affects students' attitudes and behaviour, we investigated the effects of students' sense of distributive and (school) procedural justice on their sense of belonging to school and on their social and institutional trust. The study was carried out among…

The authors investigated whether participation in school-based extracurricular activities would predict social and behavioral outcomes (school membership, peer prosocial orientation, and prosocial behavior) associated with school social capital in a group of Hispanic middle school students from the United States of America. Results of hierarchical…

Objectives: This study examined the effects of Check & Connect (C&C) on the attendance, behavior, and academic outcomes of at-risk youth in a field-based effectiveness trial. Method: A multisite randomized block design was used, wherein 260 primarily Hispanic (89%) and economically disadvantaged (74%) students were randomized to treatment…

This study examines how teacher and staff perceptions of the school environment correlate with student self-reports of bullying, aggression, victimization, and willingness to intervene in bullying incidents using multi-informant, multilevel modeling. Data were derived from 3,616 6th grade students across 36 middle schools in the Midwest, who…

The objective of the present study was to develop a scale that is appropriate for use internationally to measure affective, behavioral, and cognitive dimensions of student engagement. Psychometric properties of this scale were examined with data of 3,420 students (7th, 8th, and 9th grade) from 12 countries (Austria, Canada, China, Cyprus, Estonia,…

Background: This study integrated criminological and public health perspectives to examine the influence of bullying victimization and the school environment on physical activity (PA). Methods: We used a weighted sample of 7786 US middle school students surveyed as part of the Health Behavior in School-Aged Children study to conduct a multilevel…

This dissertation is comprised of three manuscripts and presents a line of research aimed at improving the measurement of bullying in schools. The first manuscript investigated the impact of an educational video on self-reports of bullying. A sample of 1,283 middle school students in randomly assigned classrooms either watched or did not watch an…

The Technology Immersion Pilot (TIP), created by the Texas Legislature in 2003, was based on the assumption that the use of technology in Texas public schools could be achieved more effectively by "immersing" schools in technology rather than by introducing technology resources, such as hardware, software, digital content, and educator…

The Technology Immersion Pilot (TIP), created by the Texas Legislature in 2003, set forth a vision for technology immersion in public schools. Senate Bill 396 called for the Texas Education Agency (TEA) to establish a pilot project to "immerse" schools in technology by providing a wireless mobile computing device for each teacher and…
