Often, the Wikimedia environment is associated primarily with Wikipedia. In addition, there are several minor projects that serve as useful open educational resources. When a teacher is looking for inspiration, Wikipedia seems to be the only source. Indeed, there are minor projects such as Wikibooks, Wikiversity, and Wikivoyage, which are very effective resources for organizing lessons.
In this talk, we will show how to use these minor projects not only for creating lessons but also for implementing peer-education methodologies. In this lecture, we summarize several didactic experiences, starting with Wikiversity, followed by collaborative writing projects with Wikibooks.
