The need for education in moral values is increasingly being recognised today, but how is it to be conducted in schools? In particular we consider the appropriateness or otherwise of a teacher assuming the role of a neutral chairperson in discussion.Advocacy of such a stance is especially associated with Lawrence Stenhouse who saw neutrality as a procedural device in order to empower students’ own involvement. We point out many of the insights of Stenhouse's approach, but also some of its disadvantages (...) which subtly encourage a popularist form of relativism.We suggest the substitution of procedural neutrality with a different approach, that of critical affirmation. Here the teacher advocates a stance alongside everyone else. This, however, is done in a way that affirms pupils, and their right to personal views, whilst subjecting all views, including the teacher's own, to a close scrutiny, especially regarding implications for the views of others.
