I detail my reasons for my stipulations below. For now, I've run into something and I'd love your advice. I'm teaching Philosophy of Language next semester, with many of the same students, and though no one is auditing-from-afar, they want to record the lectures and use them during the semester. They say that they found them helpful in many ways: in not having to transcribe notes, and thus to be able to pay more attention in class, in having group sessions where they would listen to the lectures and study together for papers, blue book essays exams, etc.
I should say that these are students who come to every class, are diligent, committed, excited. These students are not asking for the audio files because they want an excuse not to come to class. What is my worry, then?
My worry is the same worry I have that justifies my not posting my lecture notes: I worry that it is pedagogically bad. I worry that they will adopt parroting rather than conceptual competency. The fact that this is philosophy of language makes this doubly troubling. Philosophy of language is very jargon-rich. As such, it would be very useful for them to have the audio files so that they don't feel they have to transcribe in order to get the jargon. On the other hand, being jargon-rich tends to lead to parroting. I am not worried about whether I can tell on their exams, papers, etc, whether they are parroting. Of course I can (this is always a big mistake students make - they think we can't tell when they are faking it). My worry is that I will encourage parroting and thus impede their learning. What do you think?
My stipulations: teaching is an intimate and organic process that is always developing over semesters, years, etc. I just don't want a stable file of anything I do in the classroom existing for longer than the semester in which I am doing it. In short: I am doing philosophy when I teach. If I want my philosophy to be stable, I publish. The other stipulations are obvious. I really don't want folks sharing the audio files absent contexts that would make them make more sense. I say all kinds of things that taken out of context could be taken in all the wrong ways.
