A Wiki is a collaborative space where students and teaching staff can add and edit content. Content can include links to resources such as multimedia as well as text. Users can create multiple pages inside a wiki that are easily navigated.
A Wiki is most often used as an area where students can work collaboratively on a course project. Wikis can be set up for a whole course or a group of students.
There are two types of Wikis:
Course Wiki - Course wikis gives you the option to set up a wiki page for a course that all students and teaching staff can contribute to. Course members can use the wiki tool to record information and serve as a repository for course information and knowledge.
Group Wiki - It can be useful to help group share and interact on group assignments. When grading group wikis, the grade is automatically given to all the members of the group. It is transferred to the Grade Centre for each group member. You can assign an individual group member a different grade than the group by editing the member's grade.
Other tools you should consider as well as a wiki are:
Discussion Board: A discussion board should be used for short-question-and-answer-style collaboration between students.
Blogs and Journals: Blogs and Journals are a collaborative tool that can create greater interaction between you and your students. A journal entry can include links to resources, multimedia as well as text, unlike a blog, journals can only be viewed and commented on by teaching staff, not by other students in the course. Blogs can be viewed and commented on by other course members.
