Test Teaching
On a recent road trip, I listened to the audiobook Moneyball. It made me wonder if anyone has written on the clear connection between ideas presented in the book and the focus of public education on standardized test scores.
A good portion of Moneyball discusses a man named Bill James's obsession with the way general managers in Major League Baseball were using statistics to make poor decisions about where to spend their money. Among the problems he noticed were:
- baseball statisticians have long recorded perceived mistakes in the fielding game as errors, despite that many baseball players often have to do something right in the first place to put themselves in a place where they could make an "error." He noted that the recording of errors are really just a record of statisticians opinons.
- managers put a huge emphasis on players' RBI despite that getting on base is more often correlated with team success
- pitchers' ability to accumulate saves, and thus be identified as closers (which increases their price), is actually an extraordinarily overrated asset
The connections to the way data is misused in education are crystal clear.
