‘Transactional learning’ at its simplest means learning from doing transactions. When professionals learn they often do so, as Donald Schön reminds us, by learning from within transactions – ‘knowing-in-action’. By this Schön means that professionals solve problems by constructing for themselves a repertoire of precedents, images and remembered actions. Problems are not solved by using rules alone, but are framed or constructed according to the repertoire. Professionals try out solutions for fit, re-frame, feed back to themselves, try out other solutions. The result is what Schön calls ‘;reflection-in-action’. According to him, this is what produces the doctor's “feel’ for a specific diagnosis, or a lawyer's ‘feel’ for a case, (Schon 1983).
