In the Swedish mandatory and non-confessional school subject of Religious Education (RE) all pupils are taught together in the same classroom regardless of religious or secular affiliation. According to the syllabus, RE should include content concerning Christianity, other world religions and different outlooks on life. But what representations of different religions and outlooks of life appear in the classroom practice? How is the subject shaped in interaction between content, teachers and students? The research field that concerns the content of subjects in the classroom are relatively unexplored, not least in RE. The aim of the following paper is to analyse representations of different religions and outlooks of life as they are articulated in the classroom practice of RE by students and teachers. The Interpretive approach is used as a theoretical base. Ethnography of RE-lessons in three Swedish upper secondary schools was conducted during the school year 2011-2012. Discourse analysis was used as a method for analysing representations of religions and outlooks of life. The preliminary analysis indicates that different world religions appear in much different guises. Some religions were presented based on their history, other more as lived religion. Some religions were presented as more compatible with contemporary society and as an expression of an active conscious choices, while other religions were talked about as obsolete relics and described in terms of traditions and rules religious practitioner must subject to. Non-religious outlooks of life that occurred were humanism, existentialism, marxism, system-theory.
