While I wouldn't use the phrase "speech therapy" in this context , I think there is a more charitable interpenetration of burfog's comment. We have no problem teaching Spanish speaking students English, or even constructing entire curriculum around the idea that they are still learning English while being taught. No one involved in that is under the impression that Spanish is inferior, but they recognize that, for people living in this region of the world, English is an important language to know. We have decided that AAVE and "standard" English are the same language, but that is very much a political decision (and far from the most absurd example of different dialects being the same language). However, weather we want to call it a foreign language or not, it is still not the same language that native speakers of standard English speak. Any any speaker of English who plans on interacting significantly with speakers of another dialect will be well served to treat the other dialect as a foreign language and study it appropriately.
