Web & Information Literacy for Teachers & Students (grades 6-12)

Hello all,

Has anyone found good teacher and student resources to help students develop critical-thinking skills and search skills when analyzing web-based sources?

Looking specifically for teacher's guides, lesson/unit plans and if anyone knows of good person who is developing content in this space, that would be great.

Here is one resource a teacher referred to me: http://21cif.com/

Any thoughts or pointers appreciated.

Thanks,
Rob
