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)
