I haven’t seen the movie Waiting for Superman yet, and I’m not sure I will. I think the review from The Nation makes good sense about charter schools and teacher unions.
(Full disclosure: I am a union teacher and a strong supporter of public schools.)
More than that, there is much evidence that charter schools are no better than public schools. One of the most effective school reformers is Randi Weingarten, president of the American Federation of Teachers.
