Jean Lave and Étienne Wenger, Situated Learning: Legitimate Peripheral Participation, 1991. Note: I'd say this is the least readable of the books I've covered so far, especially if you're allergic to jargon-heavy academic social science. On the plus side, it's only 123 pages (excluding bibliography and index).
