>"This isn't Kindergarten. Nobody is there to hold your hand. Just because you paid for the class doesn't mean that anybody owes you a passing grade. If you can't be bothered to pay attention to class, or don't think it's important, or just don't like the professor, then _you_ get to deal with that. If you can't, then you're going to fail."
THIS, EXACTLY. I taught college Linux/Unix classes part-time for three years (that is all I could tolerate) and after the very first semester it was obvious how I would intro the following classes. So this was my day one speech from that point after (roughly):
"This is college, not high school and not elementary school. I don't care if you don't complete assignments, nor do I care why. I don't care if you come to class or not. I don't care if you ask questions or not. I don't care if you sleep in class. As long as you are not disruptive to others in class, you can do anything you want during non-testing periods... you are all adults and are paying a lot of money to be here. I will do my very best to help you succeed in this class, if you want that help. I will try to make the material interesting and fun, too. But if you goof-off, don't pay attention, don't study, and don't complete assignments, it is highly likely you will fail this class. And that would be a shame."
Amazingly, quite a few students seemed surprised.... and usually those were the ones that later did poorly.
