Since a follow up on what students do is rather important in education, I open this discussion on grading wiki's with my first toughts:
A wiki has two important sides that can be graded: the content and the collaboration.
- The content can't be evaluated on an electronic way (can get not any better then assignement). The only thing that the system could do is keep track where the student has added/modified the wiki, provide links to those pages and highlight those phrases. So for that part, I see a grading page, with the list of students, each student followed with list of hyperlinks to pages where the student has contributed. Clicking such a link gives you the page where you see the student's writing highlighted.
- For the collaborationpart the server's processor can help the teacher's brain . I found an interesting view on that here. The tool analyses the hystory of a page and that way you can see in a graphic way who the main contributor of the page was, if the page is written by one person or by a group, who deleted and who added content...
