The system in broken most in leadership and the aforementioned colleges of education. Having seen a sameness in my engineering studies at the undergraduate level, I was surprised at the ease for a graduate degree later in life.
I also agree from personal experience on laggards in every profession. However, there are also sistinct differences in performance between teaching theory to young minds and teaching application. I have had more than teacher say it was a more challenging class when students were asking how to apply the curricula than just regurgitate it.
TFA does have good idea but a deficiency of method. This includes their impetus on critical areas of math, sciences and technology. No fruit has been produced yet and the qustionable numbers are not an abstract in the real world. In fact I would suggest they are conservative on the fallout.
As a multi-disciplined professional that has been in the technical industry and education, a Type A personality does not guarantee success or fulfillment. As I have often told many young people that have found their apparent calling, don't be afraid to move and you can stand a couple of years in just about any place. So goes TFA and the promotion, though I would say is short-lived on real committment.
Connections are the key. Some organizations do recognize the need and the way to do it. They don't have the connections for all the feel good posts but have a desire for longer-term commitment and an ROI for the people that are there.
Having seen the hardness of acceptance of professionals entering education, the one-size-fits-all union mentality, reviewed the programs for education and industry connection and councils that are supposed to increase the effectiveness of the K12 system, they all fail to put the pieces together and rebuke anyone that sees the answers that are before them.
Teachers are more the symptom and not the cause.
