For decades, women have enrolled in college in greater numbers than men, and, by many measures, have outperformed them in the classroom. But in recent years, as social scientists and student-affairs offices have focused on other differences between the genders, they have documented patterns that could explain how engagement influences student development. The focus on gender is leading some colleges to try new approaches to interacting with their students. And it is also providing some fascinating--if often maddening--hints at how differently male and female students experience college. The author reports on how colleges confront a gender gap in the ways that male and female students experience their years on campus.
