Hey Marc!
I’ve often thought the same thing. That’s why in my Institute(workshop) I get teachers to do a ‘quick write’ on how they define Inquiry and then ask them to discuss it as a team to see the differences they hold. That conversation is only really a tip of that iceberg conversation, but at least it acknowledges that there are a multitude of ways people define inquiry and we all often assume we’re talking about one thing! Ha! (Basically your point above)

You probably can guess where I stand. I believe that Inquiry comes in many forms but what we want to strive for is students asking their own deep questions to dig in deeely and uncover answers, new ideas, and more questions. In this way Inquiry becomes how people learn and a core way to understand the world, themselves and interactions within it. I could probably say a whole lot more(like a couple books worth…) but You’re hoping to get some short definitions.

Thanks for opening the conversation! Hoping to see other responses and hear what people say. 🙂
P.S. Do you think Juliani and Spencer define Inquiry as solely the act of asking questions? Seems like it in that quote … do you recommend Launch?
