The Good The Bad The Ugly... is an old feature request of mine that was aimed at educating new users about good and bad posts.
It doesn't directly answer your question, but a mechanism like this could work to educate users in other areas of the site too, like suggested edits.
From the feature request:
The Good, The Bad & The Ugly Tutorial
The purpose of the tutorial would be to highlight what the community deems to be good and bad when it comes to posting.
On the right hand side would be links similar to the Asking help content, that could popup a dialog with a few short lines / bullet points that provide information.
Reviews & Feedback
In the tutorial, after each review item has had a decision cast on it, a dialog should appear alongside the question to highlight exactly why it was good, bad or ugly, so the users can see what is expected and hopefully learn from it.
