The goal of Math StackExchange is to serve people studying maths at every level. However, being able to ask a good question is a skill in and of itself.
In order to ask a good question, you need both access to a base level of terminology and a clarity of understanding sufficient to word that question in a way that others understand your intent.
For people who are starting off in studying mathematics, these skills have not yet developed. At the moment, we can downvote and flag bad questions. These are important tools for improving the quality of MSE Q&A in total, but it is a poor tool for improving a single user's question making skills.
So, how do we assist the question askers to improve their question making skills?
