This New Teacher Project news seems to have ruined AFTie One-L’s weekend and she’s now back to arguing that the AFTie teacher transfer data (pdf) is definitive, a stance she’d previously seemed to back away from. So, if you’re keeping score at home, the argument is that district-by-district case-studies, with data, are invalidated by national data that can’t really account for a key variable here — school district size. In other words, while the plural of anecdote is not data, NTP isn’t peddling anecdotes. That said, while I don’t think the AFTie data closes the case here, there is some interesting data in their report. Leave all that aside though, I understand why they’re picking this fight, but I still think it’s the wrong one to pick substantively and politically for them. Sorry AFTies…The bipartisan vote in CA didn’t stem from ignorance.
