Willem van Valkenburg is the coordinator of the TU Delft Open Education team and project leader for an EU project on open courseware in European higher education. He discusses MOOCs and DelftX, TU Delft's participation in the EdX consortium. MOOCs are massive open online courses that are open to unlimited participants, offer online interactions, and provide certificates of completion. DelftX will offer four courses in its first year, including introductions to water treatment and aerospace engineering, through the EdX platform.
