Metaphors: approaches to teaching
the transfer conception: knowledge is a commodity to be transferred from one vessel to another, a concept consistent with Reddy’s conduit metaphor (1993);

the travelling conception: the teacher leads students into new territory and, in doing, so, gains new perspectives, too;
the growing conception: the teacher is a nurturer.
