My school has been great about not blocking wiki access to students, but I know several that do. What kind of rationale do schools give for blocking educational wikis?
Another issue that I have had to deal with per school policy is getting parent permission for posting student work to the net. Do other schools have similar policies, or is it a "wait until something goes wrong before we address it" issue at your school?
We have a similar policy about publishing student names. We are limited to first name, last initial, but I see several school sites out there with students' full names. I am curious about your policies.
My wikis, by the way, are:
