Increasing pressure on all levels of educational provision, whether academic or overtly vocational, to be to "relevant" and "useful" prompts consideration of the relation between curriculum and pedagogy in terms of the internal structure of knowledge forms. Following Durkheim's distinction between "sacred" and "profane" orders of meaning and drawing on the work of Basil Bernstein, this paper questions pedagogic presuppositions that directionality from sensory experience to abstraction posits the everyday life of the student as the foundation for the acquisition of complex, systematic knowledge. Two empirical examples are discussed: one focuses on the internal structure of craft knowledge, while the other focuses on the internal structure of mathematics as school subject. They converge in the finding that transmission of knowledge structure, whether in material or symbolic form, requires the transformation of empirical objects into theoretical objects before a connecting point can be found between the world of everyday experience and specialised knowledge forms. This is what constitutes a "relevant" curriculum.
