When a student goes into a classroom and is taught SE (Standard English), they are being taught a dialect of English. When they go home they are speaking another dialect of English, if they are speaking English. They speak one dialect of English at home, out in the schoolyard, at the candy store, on the playlot, or out in the alley.

Wow, really? Why is the language used in school so different from that used at home? My language didn't differ between the two. Now, my language differs a bit between work and home, but the difference is mostly based upon the difference in the usual subject matter. The language I use on a sports message board - a board relatively full of young males with slangy language - varies little from the language I use here or on other boards with very different constituencies.

Am I an anomaly?
