"Waag Society developed a 'mobile learning game' pilot together with IVKO, part of the Montessori comprehensive school in Amsterdam. It's a citygame using mobile phones and GPS-technology for students in the age of 12-14 (so called HAVO+MAVO basic curriculum). It is a research pilot examining whether it's possible to provide a technology supported educational location-based experience. In the Frequency 1550 mobile game, students are transported to the medieval Amsterdam of 1550 via a medium that's familiar to this agegroup: the mobile phone. The pilot took place in 2005 from 7 to 9 February and was supported by KPN Mobile's UMTS network. At its UMTS launching event KPN put out this press release, but it's in Dutch only."
