Problem sets as a concept is widely used in academics. There is also a Wikipedia entry to moot. Will someone add this as a legal tag for use across some of the Stackexchange sites?
There used to be a homework tag on StackOverflow, but it was officially deprecated and then removed in a long cleanup process. The reasons for removing the homework tag all remain true. To quote from that discussion:
- homework is a meta-tag. It describes the status from which the question is being asked, not the content of the question.
- homework might be factually incorrect - for example, it is possible to ask a basic question yet not be a student or otherwise completing an assignment.
- Copied assignments (verbatim) with no attempt at solving the problem are not real questions and should be closed anyway.
- Someone, somewhere, will feel the need to say "is this homework? is it? is it homework? Really?" then somebody else will "USE THE HOMEWORK TAG11!!11" (and I'm mildly fed up of it).
