Wikis can be used in education in several ways: Teachers can use wikis to create weekly classroom newsletters that both teachers and students can edit to keep parents informed. Wikis allow for collaborative study guides that teachers and students can modify for different units of study. Wikis also enable group projects where students can work together without sharing private login credentials. Additional uses of wikis include writing book reviews to generate reading interests, compiling questions to study for competitions, and creating step-by-step guides for technology instruction.
