Special Education is different than Deaf Education. There would be teachers who were suppose to teach deaf students to use FM or special device for sound so that they were suppose to listen or hear what the teachers said when conducting in the classroom. I was in that FM when I was in the Special Education. Also every one of us had to read lips which was not easy on lipreading. Most often hearing teachers would expect them to hear them like listening, but that does not work out well at all. So with CI just like hearing aids, it is the way to make them listen. Some deaf or hard of hearing students can manage to pick up some words or some sentences to make out what the teachers were saying. I never liked being in a Special Education program with no ASL for us to understand in the classrooms.
I agree with Shel90 that being a teacher is not a easy job but I agree that she should have done a teacher-parents conference or meeting to discuss about why their daughter should not be in the public school if not mainstream. If their daughter is put in a hearing public school only, no deaf children in the hearing public school which she should be in the mainstream school or Deaf school.
For me, I personally would rather be in the Deaf school because I had trouble trying to understand the teachers in the hearing classrooms. No Special Education after 9th grade.
So for a young deaf girl in the public school, the teacher is saying that she had tried to work with the deaf girl, even she had been teaching in the Special Education program for 15 years. You have to remember many deaf children including me want to please our parents and will only obey what the parents said. That would be years later like in high school, she will reject her parents when they do not listen to the child's needs for communication accommodations.
