This book is about the classroom, the most important meeting place for teachers and pupils in an education building. Our knowledge, however, about what happens inside this space is limited. In many respects the classroom is still the black box of the educational system. To open up this box, this volume brings together scholars from the disciplines of Art, Architecture, History, Pedagogy and Sociology. They present a wide variety of new perspectives, methodologies and sources for studying classrooms. The book examines images and representations of classrooms (photographs, paintings and pictures on school walls), writings and documents inside the classroom (school exercise books, teachers' log books and observer reports), memories and personal experiences of classrooms (egodocuments from teachers and pupils, and oral history interviews), the space and design of classrooms (architecture, school murals and the transformation of space), and material objects in the classroom (school furniture, primers for reading and school wall charts). The essays are illustrated with a unique collection of more than fifty photographs of classrooms in Europe.
