Wikis are online collaborative writing spaces that allow users to read, create, edit, and share information asynchronously. Wikis keep a record of previous drafts and allow for tracking edits made by contributors. Wikis can be used by students and instructors in a classroom setting to develop group projects, share research and case studies, provide peer review, and build annotated bibliographies or glossaries. They facilitate student-generated knowledge and self-directed learning through collaboration and reflection on course material.
