This document discusses using wikis to build and share knowledge. Wikis allow users to collaboratively read, create, edit, and share information online. They keep records of previous drafts and can be viewed and edited with a web address or password. Wikis blur authorship lines and encourage collaboration. They can be used for group projects, papers, research sharing, course notes, and more. Wikis exchange information and develop student autonomy and self-directed learning. Participation can be tracked and wikis can have structured or unstructured formats. Instructors are encouraged to provide instructions, tutorials, grading, and mandates to help students participate.
