Wikis are essentially very simple online databases, collaborative collections of information that use interlinked pages to present and organize the data. One main benefit is they can be easily updated and expanded to include new content, or edited to correct errors.
Wikis allow multiple students to share and collaborate on one or more pages of content. Pages can be created and edited quickly, while tracking changes and additions. Instructors can create one or more wikis for all course members to contribute to and wikis for specific groups to use to collaborate. Wikis can also be used to record information and serve as a repository for course information and knowledge.
You can view all changes to all pages in the wiki. It is also possible to view changes at a high level and then drill down to retrieve information about the development and contributions for any individual.
You choose whether to assign grades to student contributions to a wiki. After a wiki is set to be graded, a grade column is created automatically in the Grade Center. Individual student and group contributions then can be graded inside the Wikis tool, where all pages and edits can be referenced as the grade is determined.
An assigned grade can also be edited from inside the Wikis tool and the Grade Center is updated. Grades for wikis are changed, deleted, reverted, and overridden just like other grades in the Grade Center. Students can view their wiki grades in the My Grades tool.
