We study the peer effects of grade retention in the context of Indiana's statewide third-grade retention policy. When a retention occurs, it changes the peer group for two cohorts: rising fourth graders who lose a peer and rising third graders who gain a peer. We identify peer effects in both cohorts by leveraging plausibly exogenous variation in…

The current study was designed to evaluate the effects of a tootling intervention, in which students report on peers' appropriate behavior, modified to incorporate ClassDojo technology, on class-wide disruptive behavior and academically engaged behavior. An A-B-A-B withdrawal design was used to evaluate the effects of the intervention in 3…

This study examined age-related changes in friend similarity on delinquency to determine whether deviant behavior homophily peaks during mid-adolescence. A community sample of 1,663 male and 1,826 female Swedish youth from Grade 5 (M = 11.21 years) to Grade 10 (M = 16.25 years) provided self-reports of delinquency. Friendships were identified from…

This study is aimed to gain insights into adolescents' classroom peer climate by examining descriptive and status norms of academic and social behaviors. Descriptive norm was assessed as the average score for each behavior and status norm was assessed using the correlation between each behavior and social status within each classroom. Expanded…

This research investigated how the level of disruptive behavior and friend influence on disruptive behavior varies across classrooms in relation to teacher emotional support. Data were collected from 48 fifth- and sixth-grade classrooms (N = 879 students) and included classroom observations at Wave 1 and student reports of their disruptive…

The potential for behaviourally challenged students to negatively impact typically developing students is a concern shared by many parents and teachers. However, deviant peer influence during workgroup activities has not been thoroughly investigated through systematic observation of deviant interactions. This study compares sequences of deviant…

This longitudinal study examined associations between changes in School Connectedness and changes in Affiliation With Deviant Peers among students from high-poverty backgrounds during the year immediately following the transition to middle school. Sixth-graders (N = 328) attending two middle schools in a large school district completed measures of…

This study examined the effects of culturally relevant/responsive, computer-based social skills instruction on the social skill acquisition and generalization of 6 urban African American sixth graders with emotional and behavioral disorders (EBD). A multiple-probe across participants design was used to evaluate the effects of the social skills…

Although childhood shyness has been associated with school-adjustment difficulties in contemporary research in China, the conceptual mechanisms that may underlie these relations remain underinvestigated. The goal of this study was to examine a complex theoretical model that explicates the roles of both peer preference and teacher-child…

Longitudinal data from 746 adolescents in Toronto, Canada (54% females), was gathered in eight waves over seven years (1995 through 2001), beginning when the youths were 10 to 12 years old (mean age = 11.8, SD = 1.2 years). Five trajectories of substance use were identified: chronic-high, childhood onset-rapid high, childhood onset-moderate,…

Aggressive and weapons carrying behaviors are indicative of youth violence. The theory of planned behavior is used in the current analysis to improve our understanding of violence-related behaviors. We examine the influence of perceived behavioral control (self-control and decision making) as a part of the overall framework for understanding the…

Continuity and change in children's involvement in bullying was examined across the transition to middle school in relation to externalizing and internalizing behavior problems in fifth grade and peer affiliations in fifth and sixth grades. The sample consisted of 533 students (223 boys, 310 girls) with 72% European American, 25% African American,…

The purpose of this mixed method study is to explain the ecology Black males experience as they transition from elementary school to middle school in terms of behavior. The Black male graduation rate is well below 50% nationally (Orfield, Losen, Wald, & Swanson, 2004; Schott Foundation for Public Education, 2010). Graduating from high school…
