Where is the Student Feedback?

Student feedback seems to be completely overlooked as a viable tool in assessing teaching and learning. Does anybody know of a school district that revises its pedagogy, based on what kids have to say? Traditional educators, whether they will admit it or not, cling to a strong distrust of kids. It's more about compliance than community and collaboration. No wonder it's so tough to find student voices as a positive force in curriculum and other matters.

I'm thinking about the best way to start a blog or wiki that invites students to provide useful feedback to educators...not sure yet about this one.
