Dear Philosophy Teachers, What are your thoughts about bringing in guest lecturers? (pretty cool!)
What about video-taping other's lectures and showing them in class as guest lectures? (still ok but not as cool?)
What about making such guest lectures available for online students to stream? (that pushes the coolness factor up a bit, since they'd otherwise watch the same lecturer all the time, right?)
And now my real question.
How long can I keep using those same video-taped guest lectures? They're always and forever fresh to each new batch of students, after all. So for how many years can a guest lecturer be dead before I stop calling him a "class guest"?
