Tonkin (2005) identifies four categories of the wiki use in the education field:
Single-user: This use allows individual students to write and edit their own thoughts. So, it's useful for revision and monitoring changes in understanding over a period of time.
Lab book: This use enables students to peer review notes kept online by adding commentary, annotations or other additions to existing lecture notes, seminar discussions, lesson plans, etc.
Collaborative writing: This use can be used by a team for joint project or research such as a group initiative, essay or presentation.
Knowledge base: Through collaborative entries, students can create course content that supplements and extends delivered material.
