I don’t know ASL or SEE, let alone much beyond a couple of spoken languages but this was an interesting question as I’ve never heard of SEE—so I Wikied it.
The argument against SEE mentioned in the Wiki article is that ”... it distances deaf children from deaf culture.” I can imagine that happening. While one of the arguments for SEE is ”...that it provides children with a visual form of the English language.” The latter struck me as being quite redundant in that a person who’s deaf doesn’t also mean that they’re blind, in that they should be able to read just fine.
I’m not an educator nor am I deaf but I would think placing an emphasis on visual communication—using ASL which is a language created out of necessity rather than in the case of SEE which seems to have been devised out of opinion—and literature would be the best way the stimulate a student’s interest and understanding in language.
A friend’s been talking about taking a Sign Language course later in the year I might see if I can go with her because as far as I know there’s quite a large deaf community where I live.
