The anti pre-k arguments Lisa Snell and Shikha Dalmia of the Reason foundation made in the Journal last Friday were based on a paper they published two years earlier. When the first paper came out Steve Barnett of the National Institute of Early Education Research at Rutgers rebutted both that paper and also one by the libertarian Lexington Institute in a 2008 paper. Roy Bishop, the president of the Oklahoma Education Association, linked to Steve's rebuttals on his blog.
