A large fraction of Jamaicans grow up speaking Jamaican creole, and when they later go to school and have to use English without having used it before, many fail. Jamaica is now considering converting the schools to a bilingual curriculum designed to teach children both languages.

It is well established that a carefully designed bilingual curriculum is effective at graduating students who can speak and write both languages — more effective than dumping students precipitously into taking class using a language they don't really know. Americans who want to make sure immigrant Hispanic children in the US become good in English should support bilingual education.

I suspect that the opposition many right-wing Americans display towards this is a way of venting resentment at those children for being present in the US, not a serious effort to help them learn English.
