Colorado is joining a group of eight other states that are seeking to change the way colleges and universities train teachers, as they seek a way to produce an effective educator for every classroom. The focus is, of course, on the practice of teaching - notably expanding the in-classroom experience. The idea of teacher education as an "internship" seems to be relevant in this case. The plan reminds of a book I read a decade ago called The Conspiracy of Ignorance. The author called for the elimination of bachelor degrees in teaching and instead envisioned a Master's degree program for teachers who have completed a bachelor's degree in content. He also argued for higher academic standards for teachers, requiring that teaching candidates only come from the top third of their class.
While there are reasons to criticize this idea, it is more in line with teacher education practices around the world. I've argued before that there are only so many "Superman" teachers, and I really think an effective teacher is much more a natural characteristic than a taught skill. But that's not an absolute position. It will be interesting to see where this goes.
