It seems that I wasn't clear about what I'm asking:
I've noticed that new users might not always post the best questions and subsequently have their questions closed. Usually the users with low reputation end up writing questions that get closed, so is there a way which SO can make them take an extra step or two before they post their question so that we ensure their question is not closed? These extra steps should only be present until the user gets a slightly higher reputation. I think this would save people some time and effort when they're answering a question which may potentially be closed.
Here is an example where the OP could have done a quick search and found the answer to his homework question and not have his question closed:
