Mathematical Intimidation: Driven by the Data, John Ewing
"Of course we should hold teachers accountable, but this does not mean we have to pretend that mathematical models can do something they cannot. Of course we should rid our schools of
incompetent teachers, but value-added models are an exceedingly blunt tool for this purpose. In any
case, we ought to expect more from our teachers than what value-added attempts to measure."
