I watched a BBC Radio show Tutor verses Teacher and found it raised some interesting points.  The main point I gained was that teaching is different from tutoring in so far as a teacher is the leader of a class of about thirty, follows the national curriculum and plans detailed lessons with provisions for discipline, differentiation and the regular marking and assessing that goes along with it.  Both camps claim legitimacy, but it is my opinion that teaching in the traditional sense will radically change in the next few years and that this will include a part or complete dismantling of the current education system; and in light of how concentrated and effective private teaching is, I would say that this can only be a great thing for all humanity and related creatures...
