Fortunately, Korea's a little less like that. That said, to be safe I never meet a student in a room with no camera. That camera's my safety net. LOL, a camera! I tell kids jokingly some of the items in my room are cameras...lol. I just never allow myself to be in a room alone with a student, and if one comes in while I'm at my desk and the room is empty (only one or two periods a week) I will get up and walk towards the door.
