This is just my opinion as a hearing observer. I have interpreted for all grade levels, although my "specialty" is two-year college level.
I have seen some teachers (and sadly, some terps) make too many "accommodations" for Deaf students. They spoon feed and carry the students thru school, thinking they are "helping" them. Then the kids graduate with good grades, and get POW! hit in the face with real world expectations.
On the other hand, I wouldn't want to see schools go back to the "good old days" as HoneyShot described where a Deaf student had to sink or swim totally on his/her own with no accommodations.
Actually, I don't even like the word "accommodation". That sounds like begrudingly giving into someone's whining. I prefer the concept of offering "support services". Here's the difference:
"Oh, your child is Deaf? What
must we do (to meet legal requirements) to
accommodate (silence your whining about) your needs?"
or
"Oh, your child is Deaf? What
can we do (to meet educational goals) to provide
services that will
support (make possible) your access to equal education?
Schools should provide technology/equipment (especially for notetaking), captioned video materials, tutoring services for vocabulary building and other language skills, and interpreters or oral facilitators.
Schools should NOT let Deaf students "skip" assignments, ignore deadlines, let terps "help" with the school work, or get extra credit just for "trying" or showing up.
Just some random observations by "the fly on the wall" in the classroom.
