Forging the jewels of the curriculum: Educational practice inspired by a thermodynamic model of threshold concepts [PDF]
, 2014 In this article, a thermodynamic view of learning is taken. Internalisation of a threshold concept, the so-called act of “passing through the portal”, is viewed as a phase change. It is postulated that threshold concepts are associated with learning that
