Areas of student reaction to the university, including student activities, opinions about college, perception of the college environment, and estimates of gains were investigated. Subjects were a random sample of undergraduate students at the Indiana University (Bloomington campus) in the spring of 1979, who completed the Pace College Student Experiences Scales. Results indicated that: (1) the intellectual impact of the university is considerably bolstered by activities outside the formal classroom; (2) the higher the class rank, the more students participated in extracurricular activities; (3) men reported significantly more involvement in athletics, and women in interpersonal activities; (4) women reported more gains than men in literary and aesthetic areas; and (5) off-campus students tended to report more gains in understanding scientific applications and technological developments than on-campus students.
