[An expert should be a teacher rather than a process supervisor].

Most medical schools in the Netherlands have replaced 'old-fashioned' lectures by teaching in small groups. This system requires so many teachers that it largely depends on junior staff, who have no specialised knowledge of the subjects at hand but act as a supervisor while students teach each other. Oddly enough some regard this as an advantage. In general it is a shoddy substitute because teaching is an art, because students cherish proper explanations and because the students are deprived of.
