That's why I am wary of deaf children today being mainstreamed....
Me too. I've experienced both and although the special school I went to DID leave a lot to be desired accademically the bullying didn't ever get as bad as it did in the first high school I went to. I also went to Royal National College for the Blind (RNCB) and they have excellent accademic standards. I passed most of my exams there.
I only became blind at the age of 17 so can't say exactly how a deafblind child should learn but I think they would do best with a one to one teaching style (or at least a small group) using deafblind manual, Hands on sign language or BSL. They should learn braille literacy, IT (information tecnology, hands on signing or BSL (depending on how much residual sight they had), long cane tecnique and other blind skills and as much tactile information as possible. I think teachers typically try to focus too much on any residual sight/hearing the child may have.
