I'm not a teacher, but I came across this excellent video by teacher C.G.P. Grey explaining his system for organizing and managing his teaching life. While it is in part an ad for his time-management coaching services, it actually seems useful on its own -- and he's giving away what appears to be the good stuff, rather than holding it all back for paid customers.
So what do you think, teachers? Is this good stuff? What tips would you add? Also check out the YouTube comments for some helpful tips (and, uh, some crappy YouTube comments).
For the record, I don't know this guy and have no connection to him. But his YouTube videos are really great.
