Always the beautiful answer, who asks a more beautiful question.
- E.E. Cummings
General techniques for asking good questions:
- Isolate the components
- Consider all the attributes and combination of attributes
- Explore white space (missing aspects)
- Consider extremal cases
- How does X depend on Y?
- How to measure?
You will only refine this craft with practice. So ask more questions in conversation. Ask more questions in the classroom. Ask more questions of yourself. Why are you doing what you're doing?
