One clue comes from a little-known 2003 study based on Organization for Economic Cooperation and Development (OECD) data that compares the world's 15-year-olds on two measures of student engagement: participation and "belongingness." The measure of participation was based on how often students attended school, arrived on time, and showed up for class. The measure of belongingness was based on how much students felt they fit in to the student body, were liked by their schoolmates and felt that they had friends in school. We might think of the first measure as an index of academic engagement and the second as a measure of social engagement.
On the measure of academic engagement, the U.S. scored only at the international average, and far lower than our chief economic rivals: China, Korea, Japan and Germany. In these countries, students show up for school and attend their classes more reliably than almost anywhere else in the world. But on the measure of social engagement, the United States topped China, Korea and Japan.
In America, high school is for socializing. It's a convenient gathering place, where the really important activities are interrupted by all those annoying classes. For all but the very best American students the ones in AP classes bound for the nation's most selective colleges and universities high school is tedious and unchallenging. Studies that have tracked American adolescents' moods over the course of the day find that levels of boredom are highest during their time in school.
One might be tempted to write these findings off as mere confirmation of the well-known fact that adolescents find everything boring. In fact, a huge proportion of the world's high school students say that school is boring. But American high schools are even more boring than schools in nearly every other country, according to OECD surveys. And surveys of exchange students who have studied in America, as well as surveys of American adolescents who have studied abroad, confirm this. More than half of American high school students who have studied in another country agree that our schools are easier. Objectively, they are probably correct: American high school students spend far less time on schoolwork than their counterparts in the rest of the world.
Trends in achievement within the U.S. reveal just how bad our high schools are relative to our schools for younger students. The National Assessment of Educational Progress, administered by the U.S. Department of Education, routinely tests three age groups: 9-year-olds, 13-year-olds, and 17-year-olds. Over the past 40 years, reading scores rose by 6 percent among 9-year-olds and 3 percent among 13-year-olds. Math scores rose by 11 percent among 9-year-olds and 7 percent among 13-year-olds.
By contrast, high school students haven't made any progress at all. Reading and math scores have remained flat among 17-year-olds, as have their scores on subject area tests in science, writing, geography and history. And by absolute, rather than relative, standards, American high school students' achievement is scandalous.
In other words, over the past 40 years, despite endless debates about curricula, testing, teacher training, teachers' salaries and performance standards, and despite billions of dollars invested in school reform, there has been no improvement none in the academic proficiency of American high school students.
It's not just No Child Left Behind or Race to the Top that has failed our adolescents it's every single thing we have tried. The list of unsuccessful experiments is long and dispiriting. Charter high schools don't perform any better than standard public high schools, at least with respect to student achievement. Once one accounts for differences in the family backgrounds of students who attend public and private high schools, there is no advantage to going to private school, either. Vouchers make no difference in student outcomes. No wonder school administrators and teachers from Atlanta to Chicago to my hometown of Philadelphia have been caught fudging data on student performance. It's the only education strategy that consistently gets results.
We need to rethink high school in America. It is true that providing high-quality preschool to all children is an important component of comprehensive education reform. But we can't just do this, cross our fingers, and hope for the best. Early intervention is an investment, not an inoculation.
In recent years experts in early-child development have called for programs designed to strengthen children's "non-cognitive" skills, pointing to research that demonstrates that later scholastic success hinges not only on conventional academic abilities but on capacities like self-control. Research on the determinants of success in adolescence and beyond has come to a similar conclusion: If we want our teen-agers to thrive, we need to help them develop the non-cognitive traits it takes to complete a college degree traits like determination, self-control and grit. This means classes that really challenge students to work hard something that fewer than one in six high school students report experiencing, according to Diploma to Nowhere, a 2008 report published by Strong American Schools. Unfortunately, our high schools demand so little of students that these essential capacities aren't nurtured. As a consequence, many high school graduates, even those who have acquired the necessary academic skills to pursue college coursework, lack the wherewithal to persevere in college. Making college more affordable will not fix this problem, though we should do that too.
The good news is that advances in neuroscience are revealing adolescence to be a second period of heightened brain plasticity, not unlike the first few years of life. Even better, brain regions that are important for the development of essential non-cognitive skills are among the most malleable. And one of the most important contributors to their maturation is pushing individuals beyond their intellectual comfort zones.
It's time for us to stop squandering this opportunity. Our kids will never rise to the challenge if the challenge doesn't come.
