European school books present a distorted image of Islam and Muslims, using stereotypes that breed mistrust of the faith and its people, a five-country study published Thursday showed. This slanted view reflects "cultural racism," concluded Germany's Georg Eckert Institute for textbook research, which analysed 27 volumes used in classrooms in Britain, France, Austria, Spain and Germany. The report, which was presented at the foreign ministry in Berlin, was billed as the first of its kind in Europe. "Islam is always presented as an outdated system of rules which has not changed since its golden age," Susan Krohnert-Othman, the institute's project director, told reporters. The researchers concluded that Islam is frequently presented as a homogenous entity without reflecting its diversity in different parts of the world. The report did not find major differences between the five countries studied. The textbooks used at the secondary school level frequently set an "antiquated Islam" against a "modern Europe" and depict them as in conflict with each other. Krohnert-Othman said that such representations "cannot challenge populist Islamophobia" among pupils. "Even modern European school books include oversimplified presentations of Islam and they stand in the way of a credible intercultural dialogue with the Muslim world," said Germany's minister of state for European affairs at the foreign ministry, Cornelia Pieper, after reading the study's findings. The researchers called on schools to present information on reforms advocated by Muslim clerics and intellectuals as well as the modernisation process within the religion. And they said instruction on cultural diversity needed a major overhaul. "Muslims must no longer be classified as a separate group consisting of non-European immigrants whose traditions prevent integration," the researchers concluded.
