As a board member of the edu-sharing NETWORK Association, I am networking educational actors and institutions and promoting the use of innovative open-source software. In addition, we open up learning content sources for educational institutions and bundle resources for open-source and open-content projects. In the current project JOINTLY OER, we support OER multipliers with an OER-Content-Buffet, an IT-cooperation and hackathons, expert meetings as well as webinars and more. For the edu-sharing.com open-source team, I organize community and network work, quality assurance, strategic planning and usability. As a member of ZUM.de, I am working and networking for challenges that can be solved with IT.
