Wikis are web-based or server-based platforms that allow users to collaboratively create and edit web page content. Wiki pages consist of constructed knowledge and information in article form as well as discussion pages for commenting. Wikis support social learning by enabling collaborative writing, building content knowledge, and creating a portfolio of learning through shared projects. They are well-suited for project collaboration and knowledge sharing.
