A question word is a word used in asking open questions - that is, questions which ask for information. They are also known as wh-words (as most of them, with the exception of how begin with wh-). Many of them are also used as relative pronouns.
When talking to students teachers should attempt to pose questions using question words to encourage longer and more descriptive answers from students.

The Five Ws
In journalism, the Five Ws is a formula for getting the "full" story on something. In order for a report to be considered complete, it must answer a checklist of six questions consisting of the Five Ws (and one H):
- Who? Who was involved?
- What? What happened?
- When? When did it happen?
- Where? Where did it happen?
- Why? Why did it happen?
- How? How did it happen?
