That was an amazing and surprising find re. Milwaukee charters. I thought that at the very least they'd get the advantage of being in a more diverse (integrated) setting with more middle-class kids and that being chosen (even by lottery) would produce a kind of halo effect. Why it didn't is what should baffle the media. But it doesn't.I comment:
Or perhaps, your implicit assumption that diverse (integrated) settings with more middle class kids confers an educational advantage which leads to improved student performance is invalid.
The assumption rests on shaky empirical support in the first place. So, one would think that this additional piece of potentially-negative evidence might lead an un-biased thinker to question her underlying assumptions. Why it doesn't baffles me.
PS: This might be one of the best examples of irony I've ever seen in an education blog.
PPS: It's also a good example of why we never make any progress in education. Policy thinkers become so wedded to their pet assumptions and will bend over backwards to discount contrary evidence. Classic Confirmation Bias.
