Please, please, please ban homework altogether. Allowing homework has resulted in a deluge of questions from users with a reputation of 1 asking us to do their work for them. Yes, we can tag then ignore homework questions, but (a) that requires us to be continually editing tags and (b) it makes the site look rubbish for anyone not au fait with filtering by ...

Questions that can be summarized as "I want to solve this problem but do not know how. What relevant physics do I need to research/learn to solve it?" are ON topic.

Questions which ask us to perform calculations are off topic.
This is too broad. I recognize that it's intended to head off boring copied-from-homework questions like "what's the optimal angle for a 45 mph banked turn if the coefficient of friction is μ = 0.233457821234 also are all those digits important kthxbye". However calculation questions like "...

ToughSTEM - A question answer community on a mission
to share Solutions for all STEM major Problems.
This is a site built specifically for answering STEM (Science, Technology, Engineering, and Mathematics -> Physics) problems in a Q/A format like the stack exchange network. We love check my work questions. It is and always will be 100% free. Supports ...

I thought it would be worth distilling my thoughts into a concrete proposal. This is essentially what Manishearth already proposed - I'm just hoping to make the idea clearer.
In many ways it is not a big change to the current policy, but it is a big change to the way the policy is presented, and I think it would have a lot of benefits.
The current homework ...

Yes, we should.
"Homework" isn't the issue
I think we all agree that whether or not a post comes from a homework assignment is irrelevant, as illustrated by this example question:
Consider a transmon qubit with capacitance C and Josephson junction critical current I_c. What is the matrix element <1|Q|0> for this system?
I might be motivated to ask ...

Physics Problems Q&A aka Physics Q&A Exchange
(currently out of order)
This is a site specifically aimed at physics problems/exercises. It was started in November 2016 to provide a suitable place for questions on Physics Stack Exchange in the homework-and-exercises category which show some effort but are closed as off topic because they are not ...

The current policy is summarised as "we do accept homework questions, but only if X, Y, Z". It would be better to move to a policy that says "we do not accept homework questions. However, if you do X, Y and Z it will not be a homework question any more and we can accept it."

Recently I've noticed a few people posting questions in rapid succession, each with a screenshot of a problem. If you look at the questions as a whole, it's obvious they've split their entire problem set or take-home exam into tiny pieces and asked us how to do the whole thing.
This sort of behavior, which is undesirable but not necessarily obvious to ...

While I disagree with the specific implementation, I think userØØ7's idea does have something to it.
Can we have the page respond to users entering the homework tag by showing a short homework FAQ and links to the canonical meta question? I would like to have new users confronted to the homework section of the FAQ and the How do I ask homework questions on ...

Sound pitch of glass with water
This is not a homework or homework-like question, it's not a calculation request, it's completely conceptual, but the question doesn't show any prior research, or any evidence that the poster has made an effort to figure out the answer themselves. You might think that's perfectly fine. On the other hand, if you believe the ...

To discourage rapid postings of the type alluded to in the question, methinks screenshots of text should be outright banned. I can understand a screenshot of a figure, but if it can be easily done with LaTeX/MathJax, there’s no place for a screenshot.
If anything, the time and effort going to typesetting makes it easier to justify that the OP has done some ...

Firstly, you're asking two separate questions that need to be dealt with differently. One question has to do with HW posts, and another has to do with basic posts.
The Data
Now for the data:
Unfortunately I can't cook up a query that reliably separates basic and non-basic questions.
Analysis
The last data point is incomplete (data.SE lags behind by ~a week, ...

Mutual $E$ force due to charged coaxial rings
I think this is probably homework because it's really just asking how to solve a problem. However you could argue it's conceptual in the sense that it's asking about how to approach this sort of problem for arbitrary geometries.
A belated footnote: the simplest approach I've seen to doing this requires the use ...

Three dimensional isotropic harmonic oscilator Hamiltonian
This is an advanced question (on quantum mechanics) that shows detailed effort. It could be argued that it doesn't actually ask anything beyond "what am I doing wrong?", though.
Vote up if you think this should be on topic under the new policy, or vote down if you think it should be off topic under ...

I agree with a strong caveat. The tag wiki excerpt must function as an exceptionally well-tuned tool to catch the great homework/problem-solving questions, turn the borderline cases into good questions, and prevent bad questions as far as possible.
The way tag synonyms work at Ask a Question time is the following. You type in the tag you think you should ...

Bad:
Your question looks like: "Here is my homework. Solve it instead of me, now".
You scanned/photographed your textbook.
You don't show effort or curiosity towards the solution.
You don't bother to begin sentences with capital cases or end them with a ".".
Good:
You aren't asking for the numerical solution; you want to understand how you can solve it ...

Let me draw your attention to the first sentence of the "About" page
Physics is a question and answer site for active researchers, academics and students of physics and astronomy.
The level of the site is defined as being interesting to serious students of the discipline,and has been that way since its inception on Area51.
This level of professionalism ...

No, I don't have the tag on ignore.
Upvote if this is the case. To keep the numbers clean, please don't downvote.

Let me put up the counterpoint to Manishearth's answer: while we're certainly not required by Stack Exchange to do anything about questions which violate a course policy, it's in the interest of our site to do so, within reason.
In particular, the community has been quite clear that we do not want this site to be known as a place where people can take the ...

I think there is one real (or at least, really potential) issue with problem-solving: it could be applied to almost every question on the site. Presumably people wouldn't go around editing it in willy-nilly, but it is likely that new users will apply it without discrimination to their questions.
I'm thinking "Oh, I have a problem, and I'd like it solved". ...

How about homework-and-exercises? It is self-explanatory, and that way we still call a spade a spade while simultaneously leave open the possibility that it might not be actual homework.

The How to Ask sidebar
Homework questions are not allowed on this site. You should ask about specific concepts. See our homework policy.

I have some sympathy with Brandon's point.
I'm a bit concerned we'll end up seeming an unfriendly and elitist site. The moderators are admirably tactful in dealing with homework questions, but I see comments to homework questions that while justified strike me as a bit bitchy. I worry these will put new users off - it's easy for us old timers to forget how ...

Questions which can be summarized as "This is the statement of an example problem. (Perhaps the "simplest" and/or the "most interesting" case I have been able to think of at the moment.) Rather than solving it (which I may or may not be able to do myself) I'd like you to point out some useful "standard", "technical" terminology, including some name for the ...
