Madeline turns in a paper to you that is sloppy and halfway done. You call her over to ask her about it, and she says, "Well, I finished it on the school bus on the way home yesterday, and that's why it's messy.". The best response on your part would be to say,
a. "Oh, that was clever of you, and it makes sense now why the work is so messy. Next time, be sure to complete the whole assignment, though.". b. "Homework is called homework because it's supposed to be done at home, not on the school bus. If I wanted you to do it on the bus, I'd call it bus work. You're going to have to do this again, and from now on, I want you to wait until you get home to do any work.". c. "I suppose I can accept it like this just this once, but from now on, don't be so messy.". d. "I can see why you'd want to do your homework on the bus – it saves time and shows that you're being responsible in completing your work. Unfortunately, this work is of poor quality, and you'll need to revise and resubmit it; remember, I am looking for strong effort in your homework.".
