John Spencer is a Professor. Maker. Speaker.
His website is here.
His videos, and he has a LOT of them, are fantastic.
Here are three of my favourites:
The LAUNCH Cycle: A Design Thinking Framework for K-12 Students
As an teacher who has become startup founder (Class Creator) I love the idea of teaching students how to approach problems, develop solutions and iterate.
An Open Letter to Teachers From a College Professor
If you're an elementary/primary school teacher I challenge you to watch this and NOT get goosebumps.
Design Challenge: Invent a School for Ninjas
I love short, sharp engaging ideas like this. Show your students and see what it goes :-)
