Thresholds: The metaphorical foundations of powerful knowledge

open access: yesThe Curriculum Journal, EarlyView.
Abstract This paper advances a theoretical account of threshold concepts as metaphorical‐relational structures that reorganise meaning across contexts. Building on conceptual metaphor theory, we propose that threshold concepts can be understood as sites of schema‐level reorganisation: deep, embodied patterns of relational logic that scaffold abstract ...
