With the increased requirement to incorporate counter-terrorism measures into the British education system, teachers are now expected to discuss terrorism within the classroom setting. However, this is a challenging endeavour due to the complex nature of the phenomenon, including definitional questions and links made to certain ideologies, in particular religious motivations. This paper explores my research findings from a project conducted over several years into pupils' perceptions of terrorism and its links to religion in general, as well as the specific links made with Islam, Sikhism and Christianity. To contextualise the research, a brief overview of the methods and results has been provided, followed by an analysis of the issues raised. Overall, the pupils thought that religion in general, as well as Islam in particular, was something that motivated terrorism. However, many pupils also expressed concerns about associating entire religious communities with terrorism, perceiving it as a stereotype, and expressed interest in discovering more about how and why religion was used to justify such violent attacks.
