The author explores the impact of a course on ‘multicultural education’ given to a cohort of ‘local’ and international student teachers studying to become Newly Qualified Teachers. The methodology rests on the use of a documentary on ‘extreme’ intercultural dialogue that the students discussed at the end of the course. The author hypothesises that the documentary, which is often conflictual, would help him to evaluate the students’ learning and how they discuss and problematise such a case of ‘intercultural dialogue’ in education and relate it to their future practice.
