The Association of Religious Education Teachers wants the cartoons to be incorporated into teaching materials "sooner rather than later", the DR Nyheder website reports. Studying them would help explore the relation between religious, social and political issues, according to association's president, John Rydahl. "The 'Muhammad crisis' is an obvious issue in religious education, and it amazes me that there hasn't yet been a textbook with the drawings," he says. It currently isn't obligatory to teach children about the cartoons, but many schools choose to cover the topic during history and social studies classes, according to the Danish Education Ministry.
