In The Testing Charade: Pretending to Make Schools Better, author Daniel Koretz, a Harvard Graduate School of Education professor, clearly and persuasively breaks down how our standardized test accountability system has been a spectacular failure, and yet so many of our educational and political leaders still blindly and/or stubbornly believe that high stakes, punitive testing can improve our students’ educational achievement. Some even call for more testing of “soft” skills, such as grit and social emotional learning.
The truth: according to National Research Council, with the exception of fourth grade math scores, our billions of dollars and hours spent on testing have resulted in no improvement in student scores over a thirty-year period. And even that “gain” does not persist through the upper grades. What about the famous achievement gap between underperforming sub groups and middle class white students? Since the 1980s, The NAEP Long-Term Trend assessment showed no narrowing of the achievement gap between these groups. Still, there is little public discussion on changing paths. ESSA, the revised version of No Child Left Behind, still requires federal approval of state accountability plans.
Koretz is not against measurement per se, but he emphasizes we must measure what matters, which he sums up as the Big Three: student achievement, educators’ practices, and classroom climate.
Koretz explains concepts, such as Campbell’s Law, which show how deceptive and superficial test score gains can be. He cites an example from auto safety standards. When the safety of the driver’s seat was tested, its safety improved, but the safety of the passenger seat declined. Why? It wasn’t tested. Don Campbell, one of the founders of science program evaluations and for whom the law is named, noticed that when you measure one domain, attaching penalties for failure, you gain in that domain while losing ground in the untested areas. Furthermore, our current testing regime leads to the unwanted consequences of cheating, bad test prep, the narrowing of the curriculum, score inflation, and superficial learning. Some teachers are even coached by districts to ignore certain domains in the curriculum because they are not tested. In central Texas, certain low-income, low-performing elementary schools ignore Social Studies because it isn’t tested at that level. This omission is especially disturbing when we remember that one of the goals of universal education is to foster good citizenship.
At the same time, our tests don’t measure what we should treasure: inquiry-based teaching, engaged students, project-based learning, and collaborative problem solving--- skills essential to the ever-changing American workplace.
As an educator, one of my favorite parts of the book is when Koretz contrasts two observed math lessons. One teacher asks her elementary students if a triangle or a rectangle can support more weight. The lesson begins with a student asking, “What do you mean by more weight?” A robust discussion ensues; the children come up with a hypothesis, and then the teacher distributes manipulative models of both shapes so that students can concretely test their assumptions. In contrast, a high school math teacher asks students to solve a problem. After several wrong guesses, she asks a student: What’s the rule? This student then recites the memorized rule, and that’s that. Which teacher would you want for your child? And yet the latter teacher’s students may do just fine on standardized tests.
Koretz goes on to examine what other countries are doing, specifically Finland, Holland, Singapore, and Japan, to consider other approaches. While some of their methods and practices are worth exploring, one fact remains: no other nation emphasizes punitive, high-stakes testing as does the United States. The question for all of us: is it worth it?
