The main purpose of this essay is to investigate the role of teachers of religious education in the proactive work against violent extremism and radicalization. Furthermore, the ambition is to raise awareness of how these five teachers of religious education in the Swedish upper secondary schools and primary schools in the subject of religious studies work with and implement the school's democratic mission, and to find structures to teach about radicalization,fundamentalism, pro-violence extremism and terrorism. To obtain a result, five semi-structured interviews with active religious education teachers in the upper secondary schools and theprimary schools were conducted. To show the extent to which the school's democratic mission in the proactive work against radicalization and violent extremism is carried out, the collected empirical material has been analyzed based on Paulo Freire's awareness-raising pedagogy as a theoretical framework which indicates whether the interviewed teachers of religious education work according to what Freire calls the bank view or the liberating teaching. The study shows that all interviewed teachers work according to both these models. The teachers believe that it is inevitable to ignore the teaching of facts but prefer the liberating teaching. This is because all interviewed teachers believe that through dialogues and discussions, a critical thinking is created in the students.Furthermore, it appears that all teachers find it essential to create a good and open classroom climate where there is mutual acceptance of dissent. Thus, a long-term effort to create students as source-critical thinkers is fundamental.
