This volume, the result of four years of work performed by the combined research groups of Utrecht University (Faculty of Humanities) and the HU Utrecht University of Applied Sciences (Faculty of Education), focuses on the central theme of 'Normative Professionalization'. Drawing on a wide variety of scholars including Hannah Arendt, Gert Biesta, Harry Kunneman, Donald SchOn and Chris Argyris, and engaging with professionalism, ethics, virtue and morality, this book builds the argument that learning to deal with complexity supports not only education but the personal development of teachers and the improvement of society and democracy as well. This volume presents research on a broad range of topics such as worldview education, co-teaching, moral authorship, traditional-reform perspectives on education, the discourse on citizenship, teacher education, and the question how to link religion and education. The research chapters explain the theoretical lenses and methodological approaches which have been employed to get a grip on complexity.
