dr. earl lewis, assistant professor of the sociology and black studies at the city college of new york.or joining me. you all have seen the numbers. graduation rates are low. literacy rates are low. kelly, what do you see as the root of this issue? why are we falling so low in the problem? >> it's not one issue at fall, but i think that there's no question that every study has shown that the teachers of the child particularly when they're young can make the difference if they fail or succeed. the new york times has had a dozen studies that when you focus on things that the school can control, claz size, the one thing that makes the biggest difference is the teachers the child had. i think if you have better training for the teachers. teach like a chomp on, there are a lot of teachers who want to do the good thing and aren't succeeding. getting rid of tenure. this idea that teachers can be protected. it's hard to get rid of a bad teacher than it is to get rid of a bad doctor, but it's pretty hard to believe but yet, it's much harder to get rid of a bad doctor, than a bad teacher. >> and
