The central element of the EPPOG Masterclasses 2010 will be the International Masterclasses weeks from 15.02.10 - 05.03.10, where each day up to six out of about 85 institutes participate. In addition, separate Institute Masterclasses take place, distributed over the whole year. For details on registration and travel to the institutes see: Participation. Some institutes will also hold a teacher's day (similar program, but without video conference).
