I don't sign add slips unless the student has been in class /doing the work. That's easy --
Yesterday I had several students who "joined" the class after the last meeting last week. For some of them this was a MW class, others a M night class.
NONE of them bothered to contact me about materials etc... thus ALL of them have already missed the deadlines for 15 quiz points. Sorry -- It's all on the syllabus -- which was on the internet and available to you soon after you registered for classes. This is what I'd have told them if they'd contacted me.
I wonder how many will complete the course?
I think I'm going to make note of these folks and not count them in the "DWF" statistics...
