In antiquity
pedagogy - the principles, practice and profession of teaching and learning
The idea of “liberal arts” arose in Greece and Rome as a reference to
the set of skills learned and used by free men to make the collective choices that guided civic life
by identifying, relating and debating the issues of the day.
Training in and advancement of these skills coalesced into three formal and sequential disciplines that became known individually as grammar, logic and rhetoric … and collectively as the trivium. The slave who escorted the children and supervised their education was known as the pedagogue ... from paidos "child" + agōgos "leader". At Northfield, the trivium still escorts and supervises ALL students in every subject they engage.
