Swedish students in the upper secondary school will recieve informaition regarding religion from multiple sources. If we look past the students surroundings like the family, friends or multimedia school is still the primary arena for religous education. Discussions about religion will take place in other lessons than just the subject religion. History is in my opinion the subject closest related to religion and the two makes up for a lot of the values work in swedish schools. Textbooks is still one of the most important tools for education and that makes them important as objects to study. This essay examines how religion is portrayed in textbooks for the history courses in swedish upper secondary schools. By using a qualitative text analysis I have been able to identify and discuss a few important issues that future teachers have to be aware of. The most apparent issue is how the presentation of Islam differs from other religions. Knowledge about how the textbooks present religion makes it possible for teachers and students to critically analyze the texts they are working with.
