Classrooms and schools work with and through objects all the time. Without special tools and routines [technologies], schools could not operate yet this element of schooling is obscured in histories of national schooling. The idea of a classroom without a writing surface is a puzzle or a classroom without pencils. Without the slate, the pencil and the steel nib, could the idea of the classroom have been imagined at all? Without special routines, could they be used within a classroom at all? The teacher's position in relation technologies of schooling is not clear. Sometimes they appear to be the only designed technology of a classroom, bringing tools together in simple systems for teaching and learning. At other times, teachers seem to be less significant than a new technology itself, for example the claims made for computers and lately, the Internet, as learning technologies. In poorly resourced systems, like education, schools soon begin to act as museums of technologies, sites of layers of accumulated materials. This Symposium is an opportunity to develop an interdisciplinary European wide conversation which focuses upon the production, marketing and use of educational technologies in schools, linked to educational innovations [new pedagogical movements] or general mass production. The Symposium is an attempt to encourage new work on this issue in a way which will look at the flow of materials in and around schools across Europe.
