The Zentrale für Unterrichtsmedien (ZUM) is a nonprofit organization in Germany that promotes open educational practices and resources. It launched a wiki platform in 2008 that allows schools and universities to create their own wikis. ZUM also started a teacher network in 2009 where educators can discuss and share materials. ZUM innovates through its wiki platform that enables collaborative creation of open educational content. It approaches quality by using social learning features like wikis, blogs, and forums to create and evaluate open resources.
