My proposal is simple. Should we add "share your thoughts on the problem and any attempts you have made to solve it" to the How do I ask a good question-page for all self-study related questions (e.g homework questions, a routine question from a textbook, a question from a test used for class or self-study, ...) ?
I don't think it's a good idea to try to condense the entire How to ask a homework question FAQ into a single share-your-thoughts sentence. It's more complex than that.
If the how-to-ask page is site customizable at all (it doesn't look so to me), it would be better to reference the FAQ directly, with an new section such as
If you're asking about homework (or something similar to that, such as an exercise in self-study material that the author expected the reader to be able to solve on his own), follow the advice in How to ask a homework question.
