Here’s a quick encapsulation of the education debate today: Yesterday Matt DiCarlo posts an (amusing in my view) April Fools joke about all the crazy correlation/causation inferences people make from NAEP data and the way those data are abused. Not everyone got the joke on Twitter yesterday and apparently it was too subtle – he’s since put a disclaimer in for the satirically challenged. And of course, today, here’s Diane Ravitch citing the post as a must-read because of what it purports to show. “Don’t keep it a secret,” she tells the dittoheads.
It would be entertaining except that while it was just an April Fool’s prank this is exactly how bad information and urban myths (and study laundering) travel through the education world, are uncritically repeated, and often land in the mainstream media.
Don’t keep it a secret.
