Video: Six Reasons Value-Added "Growth Model" Teacher Evaluations are Unfair

University of Virginia cognitive psychologist Daniel Willingham tipped me off to his latest video, on one of EdSec Arne Duncan's pet subjects: "Merit Pay, Teacher Pay, and Value Added Measures." Willingham gives "six reasons in three minutes" that the idea of evaluating teachers by the value-added "growth model," as reasonable as it sounds, is still unfair. Worth a watch, and good for a couple of chuckles to boot. (I wonder if Perez Hilton plans to sue.)

Besides Dan's six, what other flaws in this idea can you add?
