This document discusses using wikis in education. It begins by defining wikis as websites that allow creation and editing of interlinked pages through a web browser. Wikis are proposed as an alternative to traditional essays that supports drafting, editing and publishing. Benefits include interactive student learning and engagement through different stages of writing and feedback. Challenges include learning a new platform, but students are often more tech savvy. Successful implementation requires planning structure, routine, and anticipating problems. Examples provided demonstrate wikis for English and intensive English courses.
