This paper maintains that post Lave and Wenger VET has overlooked the relation between vocational curricula and workplace practice. The paper attributes this oversight to Kant's legacy in the "situated" tradition in VET and critics of that tradition. The paper argues that when Vygotsky's concept of mediation is allied to the recent work of Robert Brandom and John McDowell, it is possible to formulate a non-dualisitic conception of the relation between mind and world that goes beyond the Kantian separation of mind and allows us to grasp the interdependency of theory and practice. The paper concludes by outlining the implications of this philosophical and theoretical claim for vocational curriculum and vocational pedagogy.
