Interview with Harvard Professor of Education Daniel Koretz on “The Testing Charade”

October 18, 2017

As a recent Washington Post article featuring an interview with Harvard Professor of Education Daniel Koretz notes, over the past decades the American public and its political officials have sought to reform the public educational system by holding teachers, educational methods, and education officials, accountable for the performance of their students. One increasingly common way to enforce this accountability is by holding the various constituents of our public educational system responsible for student performance on standardized tests. Beginning perhaps most visibly with the Bush administration’s No Child Left Behind Act in 2002, and again augmented under the Obama administration with the passing of the Every Student Succeeds Act in 2015, standardized test scores have become the holy grail of educational achievement at the K-12 level and beyond.

But in his new book The Testing Charade Koretz puts forth a strong critique of the efficacy of high-stakes testing in evaluating the performance and utility of public education strategies and its practitioners. He illuminates among other problems, the extent to which test scores, taken out of context, miss the mark in demonstrating the value of less traditional educational programs, and the extent to which standardized tests lend themselves to manipulation, and in some cases, downright cheating. From the interview:

“Used appropriately, standardized tests are a valuable source of information, sometimes an irreplaceable one. …

But in our educational system, the use of tests has been anything but appropriate. Policymakers have ignored the fact that tests capture only some of what we want students to accomplish and even less of what we want schools to do. And they created perverse incentives that led educators to cut corners and inflate scores. Ironically, this made test scores less valuable than they would have been. Inflated scores don’t provide a trustworthy indicator of what students actually learn.

For well over 60 years, testing experts have warned educators that pressure to raise scores would cause score inflation and that test scores by themselves are not sufficient to evaluate schools. Over 40 years ago, in one of the most cited papers in the social sciences, Don Campbell repeated the warning about score inflation and the corruption of instruction. As I note in “Charade,” studies documenting bad test prep and score inflation in response to high-stakes testing started appearing almost 30 years ago, and the first study documenting more severe score inflation among disadvantaged students — and, hence, illusory improvements in achievement gaps — was published more than 15 years ago. And very consistent evidence of these problems continued to accumulate over the years.

So … why did people persist with this approach despite all of those warnings and all of the evidence? Just based on my own experience, I think it was for several reasons. Some policymakers simply didn’t know; most don’t read social science; and many had no experts on hand to warn them.”

Fortunately, with Koretz’s The Testing Charade now we do.

The Limits of “Diversity”

October 9, 2017

In recent years, diversity has become a hallowed American value, shared and honored in a wide range of contexts. And even as the concept has faced renewed criticism since the rise of Donald Trump, it remains a much-praised cornerstone of corporate, educational, and civic values. But what do we mean by it? What are we talking about when we talk about diversity? What goals is it intended to serve? And who is it for? The answers to those questions are surprisingly hard to pin down, and they vary by context. Ellen Berrey has been studying diversity for years, in neighborhoods, colleges, and corporations, and in a piece for Salon a few years ago, she was blunt about what she’s discovered: Here’s what I’ve learned: diversity is how we talk about race when we can’t talk about race. It has become a stand-in when open discussion of race is too controversial or — let’s be frank — when white people find the topic of race uncomfortable. Diversity seems polite, positive, hopeful. Who is willing to say they don’t value diversity? One national survey found that more than 90 percent of respondents said they valued diversity in their communities and friendships.

Zzzzzzzzzzzzz . . . .

Sure–there are some subjects you wouldn’t ever go to a student for an opinion on. Proper nutrition, for one. Work-life balance, for another. But sleep? Oh, they understand sleep. That may be because it’s all they do–or it may be because they barely do it at all. But their knowledge? Rock solid. So to assess The Science of Sleep,  we turn to one of our student employees, Tunisia Kenyatta, an undergrad who, when we’re not loading her down with work for our publicity team, studies in the Department of Comparative Race and Ethnic Studies. Penned by Wallace B. Mendelson, retired professor of psychiatry and clinical pharmacology at the University of Chicago and former president of the Sleep Research Society, The Science of Sleep illuminates a phenomenon that has for far too long been kept in darkness. Approaching the topic of sleep from not only a scientific standpoint, but also evolutionary, historical, and social ones, the book offers an understanding of sleep in packaging that is accesible and valuable to those both inside and outside the realm of science. Mendelson did not hesitate to cast a wide net. In addition to the elements of human sleep states and clinical sleep disorders being thoroughly addressed, the book debunks . . .
