The class that is on one set of days has "lost" about one third the students. On any given day, only about 14 students are present of a class listed at 23. The class itself takes place at mid-day, so one would imagine that it is neither too early or too late in the day to reasonably justify many of the students not showing up. But the students who are left are a pleasure to teach; they participate thoughtfully in class discussions, always have their work done, and, if they don't, generally don't make excuses. They are engaged with the readings and invest real time and effort in the essay writing process. Their grades are generally good, and even those whose grades aren't stellar are making a real effort.
My other class is first thing in the morning. I don't think one student has dropped it, and they all show up consistently and persistently. But the class is painful. While they all show up, more than half the class doesn't seem to have done the homework. No one wants to offer any sort of meaningful contribution to class discussions. They visibly resent any work they are assigned. And the list of excuses I get from them is bordering on infuriating (this is the class that inspired my post on ethos and emails). And while they all dutifully go through the motions on the writing process, they rarely ever actually change anything in their papers. And it shows in their work. Grading their papers is an exercise in endurance.
The content in the classes is exactly the same; same readings, same assignments, and ostensively I'm giving the same lectures. But of course, the dynamic in each class is completely different. But it leads me to wonder how we can effectively evaluate teaching (or, to use current rhetoric, ensure accountability)? I don't know how this different dynamic will translate in my students evaluations at the end of the semester. I'm also not sure that if the results of a peer evaluation would be the same if they came to one class over the other. On the one hand, I have a dynamic class with lots of absences, versus a less dynamic class with stellar attendance. Does my apparent failure to engage my early morning class reflect a teaching deficiency on my part anymore than my success in the later class represent an inherent gift or talent? Nor will the final class average really reflect communicate anything meaningful; thinking about it, the two class averages will probably turn out to be identical, with one class of failures because of no-shows balancing out some very good students, while the other class will just generally be lower.
We, as teachers, cannot control what kinds of students we get in our classes. If they drop or not is not always a reflection of the job the teacher is doing. Nor is their willingness to take the work seriously or their ability to do it well. I am not afforded the flexibility to simply throw out the syllabus because it is not working in one of my classes. I can't control what time of day I teach (students HATE morning classes). I can teach the same course in two different classes and get two completely different results. I'm not saying that we shouldn't evaluate and give periodic feedback on professors' performance in the classroom; I'm saying we need to take the long view and remember, so much of this is out of our control.
