Currently the "homework" close reason looks like this:
Homework-like questions should ask about a specific physics concept and show some effort to work through the problem. We want our questions to be useful to the broader community, and to future users. See our meta site for more guidance on how to edit your question to make it better
However, we get quite a lot of posts where someone posts a homework question, and then writes their attempt at a solution (without any real explanation, just the equations and numbers they used) and asks whether it's correct. Such "check my work" questions are also off topic according to the linked meta post, but the phrase "show some effort to work through the problem" could be taken as encouraging them.
Should we change the wording to make this policy clearer? Perhaps something like this (suggestions for improvements are welcome):
Homework-like questions should ask about a specific physics concept and show some effort to understand the problem. The question must be about understanding the concept; questions that just ask us to check your work are off topic. We want our questions to be useful to the broader community, and to future users. See our meta site for more guidance on how to edit your question to make it better
This would make me feel better about voting to close such questions, because the user gets a clearer explanation of what they did wrong and how they can improve their post.
