Can the school reform movement accept constructive criticism? Gary Rubinstein hopes so. Mr. Rubinstein joined Teach for America in 1991, the program’s second year, and has now been teaching math for 15 years, five of them in some of the nation’s neediest public schools and 10 more at the prestigious Stuyvesant High School in Manhattan. He has a bachelor’s degree in math and a master’s in computer science, has written two books on classroom practice and at one point helped train new corps members for Teach for America. For years, he was a proponent of the program, albeit one with the occasional quibble.
Then, in 2010, Mr. Rubinstein underwent a sea change. As he grew suspicious of some of the data used to promote charter schools, be became critical of Teach for America and the broader reform movement. (The education scholar Diane Ravitch famously made a similar shift around this time.)
Mr. Rubinstein, who knows how to crunch numbers, noticed that, at many charter schools student test scores and graduation rates didn’t always add up to what the schools claimed. He was also alarmed by what he viewed as misguided reforms like an overreliance on crude standardized tests that measure students’ yearly academic “growth” and teacher performance. Mr. Rubinstein, who favors improving schools and evaluating teachers, says using standardized test scores might seem “like a good idea in theory.” But he also thinks the teacher ratings based on the scores are too imprecise and subject to random variation to be a reliable basis for high-stakes hiring and firing decisions.
