In his book ‘From the Campfire to the Holodeck: Creating Engaging and Powerful 21st Century Learning Environments,’ David Thornburg talks about the need to create a balance in spaces such as caves, campfires, watering holes and mountain tops.
Cave: A private area for focus and reflection
Watering Hole: A place to get things, to research, to discover.
Campfire: A place where you go to talk, share, collaborate
Mountain Top: A place for learning to be presented and celebrated.
