In Their Classic Symbolic Interactionist Study of Student Participation in College

In their classic symbolic interactionist study of student participation in college classes, Karp and Yoels found that:

A) both students and professors recognize that many students don't participate in class because they haven't done the assigned reading
B) males participate in class more when the professor is male than when the professor is female
C) professors believe that smaller classes (seminars) attract better students than larger classes
D) students and professors have different beliefs about what constitutes an appropriate level of contribution to the class discussion on the part of students
E) the amount of student participation that occurs in classroom settings is unrelated to class size
