As a teacher, I've often had students say that they turned in an assignment, but that because I don't see it, grade it, and return it back to them, that I must have lost their papers/assignments. I tend to be disorganized at times, so it's hard for me to confidently say that I really haven't lost their papers. To make matters worse, I have lost a student paper or two over the years only to find it weeks later.
How should I respond?
Notes:
- Many have noted electronic submission. I'm assuming for this question that students turn in something physical that I could theoretically lose. ;-) This also allows this question to be applicable to schools that may not use electronic submission.
