I admit that this question depends on individual situations. But I would like to have an idea.
I believe I am a top candidate at an R2 school, and their teaching load is 2/2.
I am currently a postdoc and have not taught any classes during my postdoc (3 years). Whatever courses I offer, I need to prepare materials (as you know, usually borrow from others but need to make them my own and digest).
I know once the materials are set, semesters thereafter will take less time, but I imagine prep time will still not become zero.
My question is, with this 2/2 load, how much time should I expect to spend per week when I offer new classes? My guess is, it is definitely more than 20 hours, and depending on how well I want to prepare, it can be most of the week, leaving very little for research.
Am I right?
Of course, some reduction in the first year (or even the second year) may be requested. But that is not guaranteed. I just want to see the load realistically.
Many thanks in advance!
