Inner Dialogue

This afternoon I had a roomful of guys working on lots of legos, and I felt like I was watching the magic of VirtCamp all over again. They were talking, and collaborating, and getting all excited about creating robots. They were making plans and experimenting, thinking and wondering, putting their hands and their minds to work to solve interesting problems. What can I do to facilitate their learning? Give them the tools and get out of their way!
