There are a number of ways to penalize lateness. Some instructors institute a lateness policy along with their attendance policy (e.g., two late arrivals counts as one absence). Some simply draw attention to the behavior or register disapproval when a student enters late (e.g., pausing, frowning and making a pointed comment, or posting a sign on the door such as “You’re late; please be quiet when you enter”). One instructor posts a note on his classroom door with a task – generally something mildly embarrassing like singing a verse from a song – that students must do to gain admittance if they arrive late. Another way to handle lateness is to give short quizzes at the beginning of class; students who come late will miss the quizzes and lose the points.
