Effort on homework has a profound impact on student achievement. Researchers typically use an interindividual research design to explain homework effort. In this study with a total of 511 students from Grades 8 and 9, an interindividual perspective (focus on between-students differences) was combined with an intraindividual perspective (focus on…

The purpose of this study was to identify predictors of competence among adolescents with learning disabilities (LD) who participated in a virtual supported self-advocacy programme within the risk and protective paradigm. The sample consisted of 374 adolescents with and without learning disabilities, students of the 7th to 9th grades, at 15…

This study investigated psychosocial mechanisms that may account for sex differences in internalizing symptoms of depression and anxiety during adolescence using data from a prospective, multiwave study with a sample of early and middle adolescents (N = 350, 6th to 10th graders; 57% female). Girls showed higher initial levels of only depressive…

Students have difficulty learning fractions, and problems in understanding fractions persist into adulthood, with moderate to severe consequences for everyday and occupational decision-making. Remediation of student misconceptions is hampered by deficiencies in teachers' knowledge of the discipline and pedagogical content knowledge. We theorized…

Outreach mathematicians are college faculty who are trained in mathematics but who undertake an active role in improving primary and secondary education. This role is examined through a study where an outreach mathematician introduced the concept of complex variables to junior high school students in the United States with the goal of stimulating…

Given the increased risk factors in the transition from middle school to high school, this study tracked academic and school discipline records for students receiving general and special education services as they transitioned from Grade 8 to Grade 9. The authors employed analysis of variance and structural equation modeling to determine the…

This report is a follow-up to "Gaining Ground in the Middle Grades" (Williams, Kirst, Haertel, et al., 2010). That study specified a comprehensive set of actionable practices that differentiated higher academic achievement among 303 middle grades schools in California. In doing so, the study provided a compelling and coherent account of…

Recent theory on social dominance suggests that aggressive individuals should be socially successful if they also display prosocial behavior. The combination of coercive and prosocial strategies of resource control (i.e., bistrategic control) is thought to facilitate hierarchy ascension. Adolescents (N = 929, grades 7-10) were queried about the…

The present study examines the correlates of indirect and verbal victimization by peers at school. The research is based on a nationally representative sample of 16,604 students in grades 7 through 11 in 324 schools across Israel. Self-administrated anonymous questionnaires were completed during class. Hierarchical linear modeling was used to…

The present study examines how exposure to relational aggression at school is associated with adolescents' perceptions of, and participation in, a hostile school environment. Participants were 1,335 African American and European American adolescents in grades 7 through 12 (52% female, 49% African American). Results indicate that exposure to…

This study examined the reasons that four high school students who had previously refused to attend school willingly attended an alternative K-12 school for students with special needs. The two research questions that framed this study were (a) why do students who refused to attend their regular schools willingly attend Brookfield Park? and (b) in…

The third in a series of reports from P/PV's three-year study of the role Boys & Girls Clubs play in the lives of the youth they serve, "Making Every Day Count" examines how Club participation is related to youth's positive and healthy development in three outcome areas identified by Boys & Girls Clubs of America as central to its mission: good…

Saxon Algebra is a full-year mathematics curriculum designed for 8th- and 9th-grade students. This WWC Study Report reviews a study of the effects of the Saxon Algebra curriculum on 8th-grade student achievements. Students using this curriculum were compared with students using a curriculum from the University of Chicago Mathematics Project…

The intervention potential of physical activity programs for intermediate schools (grades 7-9), could be enhanced by an understanding of how students engage with and disengage from physical activity. This study provides an interpretation of how adolescents, parents, teachers, and principals perceive students' involvement in physical activity…
