This morning, Google Alerts tells me Chalkface is now defined in Encarta. No mention of us specifically of course, but nonetheless a nice little stroke to my ego to start the day.
U.K. education teaching in a classroom: teaching in a classroom, as distinct from the other duties of a teacher ( informal )
[Modeled on coalface, from the idea of a blackboard at the front of a classroom]
No mention in the OED as yet, but ‘at the chalkface’ is to be found in the Cambridge International Dictionary of Idiots Idioms.
