Learn by making awesome things to solve problems, then attach rockets and see what happens. It's a good approach, that's more fun for all and more accessible to folks that don't learn from the book & lecture model well.
I really like the prototype, simulate, 3D print approach. Being able to take home a flying model at the end of a lesson is just awesome.
Full Disclosure: Chris, the lead on the project, has been one of my best friends for the last 25 years so I'm biased.
