It depends...(well except I don't believe in homework to begin with)

Scenario one...assign homework, go over homework as a group, provide time for student to correct errors and ask question, file homework in binder. I am fine with...no grading here defined as corrected and feedback but grade not entered into grade book. Student who didn't do it required to make it up.

Scenario two...assign homework, check to see if completed, punish if not, never mention it again, no going over, no help...why would anyone even bother. If you never provide the feedback then learning cannot truly happen because you will go through life having practiced it wrong. No grading here means no checking for correct answers and no putting it in grade book.
