The project, which involves university students and high school students, is based on the excellent English translation of Marjane Satrapi’s graphic novel Persepolis (2003, Vintage). The decision to use this text (an English translation of a French graphic novel written by an Iranian writer about her experience with cultural diversity in Iran and Austria) was motivated by the multitude of facets of intercultural understanding that is addressed in, and can therefore be trained with, the help of the narrative: intercultural understanding on the level of interaction between the characters in the text and on the level of interaction of the students with the text as well as on the levels of culture and language. The text deals with growing up in a multicultural environment and depicts a series of personal experiences to which German students, living in an increasingly multicultural society themselves, can relate from different perspectives. The project investigates the applicability of what we call the ‘learning by teaching’ approach, according to which students benefit highly from instructing other students – in this case university students teaching high school students – by putting into practice what they have learned in their teaching methodology classes. The objective of the project is to develop and sustain the ICC of high school students while, at the same time, improving the ICC of university students as a result of their teaching experience. The reflection on ICC is geared to create an awareness of its implications, enable a process of self-monitoring, and ideally lead to a positive change of attitude towards cultural diversity and habits of intercultural communicative interaction. This paper outlines the methods of studying and teaching a graphic novel that fosters the development of ICC.
