Julie, You're right, and students are keen in noticing the subtle clues to a teachers readiness (i.e. unprepared and disorganized). Even if they don't say something, they'll notice when a teacher is consistently unprepared and as a result, lose respect and regard for the teacher as someone who can help them. They talk among themselves too, and that can even transfer from class to class, and then that teacher has created one of the worst things they would ever want: "a bad reputation among students". Once the trust is broken, it's very hard to gain it back. Barry Westling
