In school bullying, witnesses play a fundamental role because their defensive reactions can stop bullying situations. However, a great majority of witnesses remain passive despite their prodefense personal beliefs. To address this gap between witnesses' beliefs and behaviors, we developed and tested two social psychology strategies, namely, the…

The Quiet Classroom Game (Radley in School Psychological Review 45: 93-108, 2016) is a class-wide behavior intervention involving an interdependent group contingency based on classroom noise level. It has been shown to be effective at increasing academically engaged behavior, decreasing disruptive behavior, and decreasing classroom noise level in…

The current study examined whether bystander behaviours in class were associated with being perpetrators of ethnic victimization and whether they moderated the association between disengagement from morality and perpetrating ethnic-based victimization. The sample included 1065 adolescents residing in Sweden (M[subscript age] = 13.12, SD=.42; 55%…

According to UNESCO, one-third of the world's youths are victims of bullying, which deteriorates academic performance and mental health, and increases suicide ideation and the risk of committing suicide. This paper analyzes a four-month parent-directed intervention designed to foster empathy in middle schoolers in China. Our implementation and…

Peer victimization represents a pervasive problem, particularly for students in middle school. Although curriculum-based prevention programs have generated small to moderate effects on victimization, these effects tend to weaken beginning with the transition to middle school. In this study, we evaluated cooperative learning (CL) as a mechanism to…

Gaming the system is a persistent problem in Computer-Based Learning Platforms. While substantial progress has been made in identifying and understanding such behaviors, effective interventions scarce. This study uses a method of causal moderation known as Fully Latent Principal Stratification to explore the impact of two types of interventions --…

We tested whether a brief self-affirmation writing intervention protected against identity-threats (i.e., stereotyping and discrimination) for adolescents' school-related adjustment. The longitudinal study followed 639 adolescents in Germany (65% of immigrant descent, 50% female, M[subscript age] = 12.35 years, SD[subscript age] = 0.69) from 7th…

The current study used latent profile analysis to find subgroups of youth based on bullying participant roles and then compared subgroups on the five bystander intervention steps (Notice, Interpret as an emergency, Accept Responsibility, Know how to Intervene, and Act). The sample included 641 fourth-eighth grade students (44.6% boys) who…

Many children with disabilities engage in less physical activity compared to their peers. This pilot-feasibility study examines the effects of movement-based desk and alternative seating on classroom physical activity, time on task, reading fluency, and reading comprehension scores in fourth/fifth and seventh/eighth-grade children with…

The Research-based Developmentally Informed (REDI) program enriched Head Start classrooms with teacher-delivered curriculum components designed to enhance child social-emotional learning and language-literacy skills. Parents received information about the program via backpack express, including weekly handouts about program topics and three DVDs…

A number of factors among schoolchildren in England are currently contributing to poor attitudes towards speaking in the modern foreign languages (MFL) classroom. Although multiple explicit strategy-based instruction (SBI) intervention studies have appeared in recent years, very few studies have focused on its effect on oral skills and, in…

Deliberate practice and having a growth mindset have been hypothesized to increase school performance. But previous studies are few, have been limited to very short interventions, and on average resulted in small effect sizes on school performance. This study compared the attitudes, performance, and behavior of 130 7th-grade students taking part…

The question posed in this analysis is: What is the relationship between text-centered dialogue and reading comprehension? This article examines one student's behaviors while reading challenging texts. This qualitative case study explored the verbal behaviors of Robert (pseudonym), a seventh-grade student receiving reading intervention. As his…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…
