I can see what you mean. I was in regular english, but I got pulled out to a special education class and I could see a big difference in their teaching style. Although their teaching style is still Auditory-based (and sometimes too heavily on auditory because some of these kids are very auditory learners) No one in that class is deaf.
Your daughter is just learning speech, so I can see why their method is different. They are trying to gain her speech and vocabulary.
