The contributions in this anthology take a praxeological perspective on the historical dynamics surrounding the emergence, organisation and transformation of school subjects. The focus is therefore primarily on the materialities of teaching, e.g. teaching materials, teaching media and the mode of dealing with knowledge - knowledge practices that make up the specialised nature of school subjects. Of particular interest are processes of debate about subjects and their content as well as cases of subjects that cannot be assigned to specific university disciplines, but which are nevertheless of particular importance for the development of school knowledge. Examples of the emergence of new subjects or the persistence of areas of knowledge as teaching principles below the level of a school subject are also addressed. Translated with DeepL.comweiterlesen
