Wikis are websites that allow easy creation and editing of interconnected web pages through a web browser. Wikipedia is a free, web-based encyclopedia that is written and edited collaboratively by volunteers around the world. For a 2D foundations art class, students worked in teams to create wiki pages summarizing key concepts, with each team responsible for one topic per week. This allowed the class to build an online textbook with visual examples and references. The instructor was then able to use the wiki for class discussions on the accuracy and quality of the student content.
