I'm just curious as to how much time my colleagues spend preparing to teach. Me, I like to get about half the time prepping as I spend in the classroom. In other words, I like an hour to get ready for a two hour class. Lately, I've been more diligent about hanging on to supplemental materials from one term to the next, so I have less to hunt down, so I can focus more on the photocopying and cutting up little bits of paper aspect our profession. I'm asking in the context of a short term assignment that starts this week. A corporate gig with an NGO which is going to include 36 teaching hours a week. I want to add as little prep time to that hour count as possible.
