Practice-based professional learning (PBPL) is understood in contrast to classroom- or theory-based learning. It is kindred to terms such as work-based learning, workplace or work-centred learning. Distinctive, though, are a concern for professional learning, and the preference for practice rather than work. While it does not disdain propositional knowledge and what is sometimes called theory, its prime interest is in the formation of self-renewing and effective professional practices—a distinct theoretical position in its own right.
