Wikis enable students to create content in your topic, thus giving them control over their learning. The wiki can also become a legacy or resource for future topics, which validates the activity and makes it authentic (product-focused). Wikis are also suitable for self-reflection as each student can have one. You can monitor the student's learning (knowledge and understanding) through a self-reflective wiki. Depending on the platform, the student could continue to build their wiki over time (beyond the topic). This would enable the student to make connections between topics and develop their learning cohesively.
The wiki tool enables participants to add and edit a collection of webpages. 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 students to collaboratively author an online book, creating content on a subject set by their teacher
as a personal journal for self-reflection on a given topic (using an individual wiki)
