> I thought they’d be all over Boost and Mindstorms. Nope. Lego is just us old guys doing skeumorphism.
LEGO is awesome. My kids liked building big LEGO stuff, love Minecraft, etc. But we never had success with Mindstorms at home.
Now I'm becoming an educator and I run some robotics teams built around LEGO -- FIRST LEGO League, etc. With -structure- and -team identity- and -competition-, Mindstorms, WeDo, etc, are terrifically interesting. Enrollment maxes every year and the level of engagement from the kids in the program is very high. I hear stories from parents about kids evangelizing robotics to the cashier at the grocery market during checkout. :P
Mindstorms suffers from being too open ended and too hard: you have to have a very high level of motivation to follow a project through to where you have something to be proud of. Without outside guidance and clear reasons to chase a goal for a long time (like doing well in competition), it all falls apart.
edit: One thing I like about the FIRST stuff is that it's a bit of a trojan horse. It teaches some kids who are not very much into STEM to begin with a lot of STEM; but it also teaches a lot of kids who are deeply into STEM better collaboration and project management skills, how to speak well, and how to master subjective evaluations. Your best STEM kids tend to only learn a little about engineering and math from it, but they learn plenty of other things.
