Maps: Use Of Student Data Not Really As Widespread As This
This Newsday story (State teacher evaluation plans) and map of states using or not using student performance data is interesting but misleading in that it lumps together states that are using or "planning" to use student data (dark blue), and treats states where they're considering using student data (light blue) differently from those who've decided against it (red).
I'm planning on giving up bagels and cream cheese, but that's no real guarantee I'll do it. I'm considering going to Spain sometime soon, but again...who knows? The overall effect is to make it seem like there's a lot more actually going on than I think there is. via @karawebley
