Teach that a "site" is the 'big picture': they came, they built (however they did it), they lived there (for however long and with however many phases, extensions etc), then they left (catastrophically, calmly, slowly over time, or in echelonned steps, however...) - leaving the buildings and holes to collapse, be subject to recuperation, de demolished etc. And help them to start recognizing these phases. Learning to dig microstratigraphically is great. Not being able to get your head out of the hole and see the 'site' (and so perhaps relativise a little the importance of your local microstrat problem in the great scheme of things) is less so.
