I'm wondering if profs who have fairly liberal policies for themselves in terms of leaving early and the occasional missed class are also less likely to be sticklers on student attendance.
If this correlation is real, consider me an outlier!
I have absorbed the culture of my school that it is the professional responsibility of the professor to make sure that his/her class is covered by a qualified colleague and not only adhere to it but believe in it.
However, on the student attendance side, I am with westcoastgirl and do not pretend to be a grade school teacher. Attendance is optional (it hovers around 90%) and I won't get into the argument whether the death of the family parakeet is sufficient justification for an excused absence. I expect my students to produce professional work and I treat them as adult professionals. I do, however, record the results of their decisions if absences result in a lack of adequate learning.
