The elementary school my son went to before in another county, they used visual phonics in their Deaf classrooms. It is a total communication school, however, all of the teachers and their interpreter aids are fluent in sign language and I have observed in their classrooms and the first language they use with the student is ASL. The visual phonics they were trained in at Gallaudet. They told me they use it primarily to teach the kids how to spell. They do not focus on talking execpt if the kid wants to. I have never seen them force a kid to talk. Some talk very well and some dont. Even the speech therapist was fluent in sign language., she worked on the different strengths of each child. I really like that school and many Deaf send their Deaf kids to that school that live in that county. Then they send them to the Deaf residential school when they get into middle school.
that is what i have observed.
