The downfall of Public Education, in snippets…

Damany Lewis, a math teacher at Parks Middle School (three miles south of downtown Atlanta, Georgia, in Pittsburgh), and other teachers complained that the legislators who wrote No Child Left Behind must never have been near a school like Parks. He felt as if he and his colleagues were part of a nationwide “biological experiment” in which the variables—the fact that so many children were hungry and transient, and witnessing violence—hadn’t been controlled. David Berliner, the former dean of the school of education at Arizona State University, told me that, with the passage of the law, teachers were asked to compensate for factors outside their control. He said, “The people who say poverty is no excuse for low performance are now using teacher accountability as an excuse for doing nothing about poverty.”

… “an effective teacher three years in a row will completely close the gap between a child born in poverty and a child born to a middle-income family.” This theory, in its earliest form, derives from a study by William L. Sanders, a statistician formerly at the University of Tennessee, but the findings, which have contributed to a nationwide effort to rate teachers rigorously, have been overstated to the point of becoming a myth. According to a recent statement by the American Statistical Association, most studies show that teachers account for between one and fourteen per cent of variability in test scores.

John Ewing, who served as the executive director of the American Mathematical Society for fifteen years, told me that he is perplexed by educators’ “infatuation with data,” their faith that it is more authoritative than using their own judgment. He explains the problem in terms of Campbell’s law, a principle that describes the risks of using a single indicator to measure complex social phenomena: the greater the value placed on a quantitative measure, like test scores, the more likely it is that the people using it and the process it measures will be corrupted. “The end goal of education isn’t to get students to answer the right number of questions,” he said. “The goal is to have curious and creative students who can function in life.” In a 2011 paper in Notices of the American Mathematical Society, he warned that policymakers were using mathematics “to intimidate—to preëmpt debate about the goals of education and measures of success.”

…the stakes for testing in Georgia have escalated. Although the state is replacing the Criterion-Referenced Competency Test with a more comprehensive method of evaluation, this fall Georgia is implementing a new teacher-evaluation program that bases fifty per cent of a teacher’s assessment on test scores. The program, along with a merit-pay system, is required as a condition for receiving a four-hundred-million-dollar grant from President Obama’s Race to the Top program. Tim Callahan, the spokesman for the Professional Association of Georgia Educators, which represents eighty-four thousand teachers, told me, “The state is going down the same path as Atlanta, and we are not exactly enthused.” He said that many teachers have become so demoralized that they’re retiring early or transferring to private schools. He told me, “Our teachers’ best qualities—their sense of humor, their love for the subject, their excitement, their interest in students as individuals—are not being honored or valued, because those qualities aren’t measurable.”
