“The students in the room were terrific at asking questions.  They had questions, rather than just sitting there; their questions were authentic, rather than attempts to show off or compete with the presenters; they weren’t afraid to ask questions that really showed the limits of their own knowledge but instead preferred to ask and learn more; they asked questions that showed they were imagining the process of discovery as well as the information known at the end.  That’s seriously impressive.  And it doesn’t happen by accident.  It’s the kind of thing that happens when a culture of a certain kind of questioning and conversation is deliberately fostered.”
