The question, 'how to do things with words?' (John L. Austin) could characterize the field of pedagogy in general, if not also practices, structural and material aspects had to be taken into account. The empirical question how social practices constitute a (binding) reality comes close to the praxeological perspective. On one side, 'praxeology' is a specific methodological approach to explore practices empirically. On the other side, it covers philosophical or sociological theories of action regarding sociality as generated by social practices and contextual structures. Practices are supposed to transmit, constitute and create ?establish e.g. social orders. The focus lies on corporal, performative and emergent aspects of the practices. All the mainly empirical studies in this volume deal with the praxeological question how sociality is generated in dynamic and relational actions in a pedagogical frame.
