Drawing on ambitions to contest violence in education the paper challenges ideas that teacher students only need to rely on evidence-based theory in their future profession. This is accomplished by analyzing and comparing theories of plurality as described in three text-books used in courses at one Teacher Education in Sweden. The textbooks express three different theoretical discourses of approaching social challenges regarding violence, plurality in education, and teacher expectations. Hence, since violence is played out in a variety of ways the logic of evidence based research is insufficient as comes to handle plurality.
