There are universities starting entire departments for "Engineering Education." I work with some dedicated and very talented folks here who are in this evolving field.
I have gotten to know hundreds of people through FIRST. And there are a couple where I have said "You need to look into teaching because you have a gift." They even post on chief delphi !
I have had the real pleasure to meet some Teach for America teachers. And some even mentor FIRST teams and post on chiefdelphi.
This program is not for everyone, but it attracts some really dedicated idealistic teachers.
