David, Students are perceptive. They notice little things. Seeing an instructor hurried, rushed, making last minute copies, disheveled and disorganized, and jumping around betwenn topics (unintentionaly) creates a lasting impression of unpreparedness. Contrasted against being there when students arrive, objective written on the board, all resources and materials laid out, and the lesson ready to go, the students will observe "this instructor is ready, and so should I be".
