Teaching dialect, sociolect and idiolect is fun.
Once, in an overseas school (overseas I more or less use RP), I taught a boy from the area in Northumberland I used to teach in. We greatly amused the other students (German,Swiss, French, Spanish, Russian) with our chat (Ah divvnt kna, Howay wi wa).
I also knew a teacher who was marked down in a lesson observation once for her regional accent. Her observer was roundly castigated later for it. It was total snobbery on the part of the observer.
