Mechanisms and impacts of gender peer effects at school

"The consequences of gender social and learning interactions in the classroom are of interest to parents, policy makers, and researchers. However, little is known about gender peer effects in schools and their operational channels. In this paper, we estimate the effects of classroom gender composition on scholastic achievements of boys and girls in Israeli primary, middle, and high schools and identify the mechanisms through which these peer effects are enacted. In particular, we examine whether gender peer effects work through changes in classroom learning and social environment, teaching methods and pedagogy, and teacher burnout and work satisfaction. In assessing these mechanisms, we distinguish between the effects generated by changes in the classroom gender composition and those generated by changes in the behavior of students. To control for potentially confounding unobserved characteristics of schools and students that might be correlated with peer gender composition, we rely on idiosyncratic variations in gender composition across adjacent cohorts within the same schools. Our results suggest that an increase in the proportion of girls leads to a significant improvement in s
