This paper presents evidence that women and men benefit from having a higher percentage of female peers in post-secondary vocational STEM programs. I use idiosyncratic variation in gender composition across cohorts within majors within branches (campuses) for identification. Having a higher percentage of female peers positively affects students in…

In a study investigating different ways to engage students in an individual preparation activity, we assessed learning from collaboration with a peer. Learning was measured at pretest, individual preparation, collaboration, and posttest. Two conditions were compared: generative preparation and nongenerative preparation. With no differences in…

Despite the fact that alcohol use by adolescents is publicly discouraged, alcohol plays an important role as a mediator of relationships between adolescents, and in the process of their becoming adults. Here I introduce the concept of situational abstinence -- refusing alcohol in certain situations while consuming it in others -- which offers a…

The present study discusses the deformation of personality in delinquent behavior and how it can be corrected. [This article was translated by Susan Welsh.]

This study estimates peer effects in diverse friendship networks by friend types. Evidence from friendship networks for 57,351 U.S. high school adolescents demonstrates that adolescents are more likely to make friends with someone of the same immigrant status or ethnicity ('similar friends') than those with different backgrounds ('dissimilar…

Most previous studies of academic dishonesty have been conducted in North America and Europe, and have focused on the contextual, institutional, and individual factors that influence students' propensity to cheat. While such studies offer useful background and structure to this endemic problem, this study aimed to gain deeper insights into student…

Despite the positive effects of sports participation on young girls' development and well-being, gender disparities persist, and sport participation drops dramatically as young girls grow into adolescence. Current reports (e.g. Tucker Center, 2018) confirm persistent gender stereotypes that influence participation, especially in masculine-typed…

This study examined the role that peer groups play in shaping students' academic re-engagement across their first year in middle school and whether influences are stronger from peers with whom students remained affiliated over time. Data were collected on an entire cohort of 366 sixth graders (48% female) in a small town. Students reported on…

Antisocial peer behavior and low parental knowledge of adolescents' activities are key interpersonal risk factors for adolescent substance use. However, how the magnitude of associations between these risk factors and substance use may vary across adolescence remains less well understood. The present study examined the age-varying associations of…

At a basic level, it makes sense to involve pre-service teachers in school-based experiences (SBE) as a way of preparing them for the teaching profession. Little is known, however, about how SBEs might prepare pre-service teachers as future teachers of particular learning areas. The purpose of this study was to explore the impacts and highlight…

The study investigated the difficulties encountered by Grade 11 teachers in teaching Senior High School General Mathematics, the reasons for the problems, and the strategies employed by teachers in overcoming the challenges with an end view of developing training design. The sequential explanatory mixed methods design was used in the study with…

Given the inherently social context of classrooms, students' beliefs are dependent on the beliefs of their classmates, particularly their classroom friends and popular peers (Ryan & Shin, 2018). I investigated the ways in which students observe and interpret teaching practices in a context of their peers with three studies with the following…

Despite greater emphasis on college and career readiness in PK-12 education, gifted Black males with disabilities still encounter various barriers in making successful transitions to postsecondary educational opportunities.

The current investigation used direct observation and coding of social conversations as a rigorous method to further assess the efficacy of the Social Tools And Rules for Teens…
