Itinerant curriculum theory: People's theory against the field's epistemicidal ethos

The Curriculum Journal, EarlyView.
Abstract The field of curriculum studies suffers from a glaring theoretical impasse. Much of this impasse has been rightly attributed to the triumphalism of the neoliberal wave that has massacred the educational hemisphere with policies and practices that reduce pedagogy to an instrumentalist praxis directly associated with the thirsty desires and ...
