"Time to Tear Down These Schools"

This is the biggest civil rights issue of our time.

(Related: I'm reading a book on education reform. The author talks about the PISA test that is used to compare high schoolers' performance across countries and he states: "Last time out, the U.S. average score was 500, just behind Poland and ahead of Liechtenstein. However . . . If America's scores were limited to those from schools in districts in which the poverty rate was less than 10 percent--Finland's poverty rate is less than 4 percent--the United States would lead the world, and it wouldn't be close . . .")

"Five ways to fix statistics"

Interesting, especially because it introduced me to a fine idea by David Colquhoun and then to his blog.  Two posts from his blog:

"We know little about the effect of diet on health. That’s why so much is written about it". (And he links to a short paper by John Ioannidis, "Implausible results in human nutrition research".)

"Placebo effects are weak: regression to the mean is the main reason ineffective treatments appear to work".
