For the past few years my self and other MOE students go in to the community and do demo's at schools for recruitment and also fund raising etc..
On of the most popular questions that we get asked is the interaction between the mentors and students, how it works.
My favorite answer is about a situation that many of the MOE kids have gone through. Our mentors will show us how to use the drill but not where to drill on the part we are working on. When we show the people at the demo all the holes in the parts I always joke about how the holes are there for weight reduction but the reason they are there is from a student having to try to mount something in different parts. They tell us we are going to be fishing and help us get the worm on the hook and then it is up to us to learn how to fish with it. The robot being built on time is an important part of what we do on the team but the learning experience is much more important part of FIRST. A good mentor will show a kid how to use the tools, safely, then watch the student learn from mistakes and gain a better understanding of the mechanical, or any other, process.
Sorry about the kinda randomness of my ideas, this subject is something I could talk for hours about ( the people that know me know that i can do it to
) With out my mentors leadership and understanding of how kids learn I still would have trouble finding what end of the hammer to use.
just my 2 cents worth
