Peripatetic

Working or travelling from place to place, staying at different locations for a short period, such as, and especially as a teacher does, in working at more than one school. The teacher analogy is apt since the word derives from the Greek peripatetikos, and the earlier peripatein, which referred specifically to the teaching style of Aristotle (384-322 BC, Greek philosopher, student of Plato, teacher of Alexander the Great), who walked about while he talked. The ancient Greek prefix peri means around, or round, and patein means to tread.
