I don't have a lot of commentary on this one, but I thought it was important enough to broadcast on the blog. Kathleen McCartney, Dean of the Harvard School of Education recently wrote on the CNN web site on the value of education reform.
One thing that I'll point out is that I've often said that people don't agree enough on what a good education is to criticize or evaluate schools based purely on test scores. I found it interesting that even at Harvard, the view is that there hasn't been enough research in education to determine what really works. I realize that it's not exactly the same point that I've been making, but it does support the fact that many of the methods used to criticize charter schools as not being effective are not necessarily proven methods of evaluating education, in general.
Related to this fact is the debate on what makes for effective teaching. See this discussion at Education News Colorado for more on that topic.
