“As Cody notes above, however, simultaneously political leaders, the media, and the public claim that teachers are the most valuable part of any student’s learning (a factually untrue claim), but that high-poverty and minority students can be taught by those without any degree or experience in education (Teach for America) and that career teachers no longer deserve their profession—no tenure, no professional wages, no autonomy, no voice in what or how they teach.
And while the media and political leaders maintain these contradictory narratives and support these contradictory policies, value-added methods (VAM) of evaluating and compensating U.S. public teachers are being adopted, again simultaneously, as the research base repeatedly reveals that VAM is yet another flawed use of high-stake accountability and testing.”
Thomas cites review after review to demonstrate that VAM is inaccurate and deeply flawed. Yet the evidence is ignored and VAM is being used as a political weapon by the odd bedfellows of the Obama administration and rightwing governors as well as some Democratic governors, like Andrew Cuomo of New York and Dannell Malloy of Connecticut, to attack teachers. President Obama made a point of praising the Chetty study in his 2012 State of the Union address, not waiting for the many reviews that showed the error of measuring teacher quality by test scores.
“The rhetoric about valuing teachers rings hollow more and more as teaching continues to be dismantled and teachers continue to be devalued by misguided commitments to VAM and other efforts to reduce teaching to a service industry.
“VAM as reform policy, like NCLB, is sham-science being used to serve a corporate need for cheap and interchangeable labor. VAM, ironically, proves that evidence does not matter in education policy.”
