The wiki activity module enables participants to add and edit a collection of web pages. A wiki can be collaborative, with everyone being able to edit it, or individual, where everyone has their own wiki which only they can edit.
A history of previous versions of each page in the wiki is kept, listing the edits made by each participant.
Wikis have many uses, such as
For group lecture notes or study guides
For members of a faculty to plan a scheme of work or meeting agenda together
For students to collaboratively author an online book, creating content on a topic set by their tutor
For collaborative storytelling or poetry creation, where each participant writes a line or verse
As a personal journal for examination notes or revision (using an individual wiki)
