Wikis
Wikis are just like Wikipedia-a collection of pages that can be edited by anyone enrolled your course (or a group). These are an option for adding interactive elements in which all of the content is displayed on a single page (or small collection of pages) and everyone works to improve an answer.
1) Click "Add and activity or resource," choose "Wiki;"
2) Name the wiki, describe it, then name the first page.
3) The first person (student or teacher) to click a new wiki page (even the first one) must click to "Create page."
4) Contributions to the wiki are created with the ATTO text editor. New pages are added by putting the name of the new page in double square brackets.
5) Pages that have been linked, but not created yet appear as red links. Students or faculty who link red links must create the page.
