Teaching political science at the "Institut d'Etudes Politiques de Paris" (IEP) for two years I teach two courses: one of my classes is on political behaviour and attitudes while the other deals with "political power, from local to European level". These classes are methodology seminars which depend on a lecture class and which aim at putting into practice what is said in the latter thanks to a series of assignments: oral presentations, essays, reading commentaries and "fiches techniques" (i.e. sort of short essays on specific topics). All these assignments are typical of the IEP, and students there get so used to them that these assignments become too repetitive in the end. That's why I decided to introduce a new kind of activity into my classes to change a little.
