Although widely accepted to be the capacity to exercise control in one’s learning, there remains confusion about what exactly this means. Failure to reconcile contradictions has left the field resigned to pluralism, describing ‘versions’ of learner autonomy according to divergent theoretical orientations. However, each version is incomplete, rendering it unreliable as a basis for practice: educational initiatives that seek to foster learner autonomy from one perspective, run the risk of inadvertently undermining it from another. In an attempt to rectify this, (...) I turn to philosophies of personal autonomy, which I analyse in relation to learner autonomy to identify criteria for its achievement, regardless of version. If we acknowledge that learners are ever embodied, emplaced and sociohistorically situated, as we must, learning is a process of identity construction in relation to context. To be in control of this process is to define ourselves in terms of authentic values, the expression of which may require resolve to stay one’s path or resistance to pressure to act otherwise, all of which is contingent on affordances and constraints that are inherent to our embodied, emplaced and sociohistorical constitution. I examine the implications of this theory for practice within educational institutions. (shrink)
