This article reports on a study using data from nation-wide standardised examinations in Poland. We analysed the extent to which grade 9 student achievements have depended on the stability of their peer group over the course of middle school. We controlled for the fixed effects of schools attended by the students, as well as for individual…

Dimensional comparisons are comparisons of one's accomplishments between two domains (e.g., comparisons between math and verbal achievements) that affect our self-perceptions in the domains compared with each other. In particular, dimensional comparisons explain the seemingly paradoxical finding, described in the internal/external frame of…

Drawing on cross-cultural qualitative research in comprehensive (primary and middle) schools in Finland and Korea, this article explores students' peer relationships as well as tensions and negotiations that occur between student agency and school control. Based on school observations and interviews with students and teachers, this article…

This dissertation investigated whether math course sequence from 8 th to 9th grade influenced 9th grade math motivation, defined as perceived competence in math, sense of belonging in math, importance of math, and math anxiety. Two competing hypotheses were proposed suggesting that a more accelerated math curriculum (Algebra 1 in 8th grade versus…

The present study investigated how efforts to enhance career preparation affect peer groups. The participants were 710 9th graders who were randomized into control and intervention groups and assessed 3 times during 1 academic year: at baseline (T1, Fall), immediately after the career preparation intervention (T2, 3 months after baseline), and 5…

The authors investigated the impact of a manualized high school transition program, the Peer Group Connection (PGC) program, on the graduation rate at a low-income, Mid-Atlantic high school. The program utilized 12th-grade student peer leaders to create a supportive environment for incoming ninth-grade students. Results of a randomized control…

Prejudice and discrimination as justifications for social exclusion are often viewed as violations of the moral principles of welfare, justice, and equality, but intergroup exclusion can also often be viewed as a necessary and legitimate means to maintain group identity and cohesion (Rutland, Killen, & Abrams, 2010).

Youth were surveyed on 5 occasions between fall of 6th grade and spring of 9th grade. At each assessment, youth reported the names of up to 7…

The present study is one of the first examining whether peer group members hold similar levels of self-regulated learning. The study specifically addresses the potential homophily among group members' regulative abilities (metacognition, environment regulation, effort regulation, peer learning, and help seeking) and whether group members'…

Despite the rapid increase in immigration all over Europe and concerns expressed for the adjustment of immigrant children and young people, studies on peer victimisation among them are scarce. By combining the predictions of the acculturative stress model with the social-ecological perspective of peer victimisation, this study compared different…

A recent report by the Mathematics Advisory Panel referred to algebra as a "gateway" to later achievement (National Mathematics Advisory Panel, 2008). To address the problem of low academic performance in algebra, an increasing number of states and districts have started to implement a policy of requiring algebra for all students in…
