Taking social class into account, U.S. students are doing better than it seems on international tests, compared to students in France, Germany, Britain, Canada, Finland and Korea, according to a study by Martin Carnoy, and Richard Rothstein. “U.S. students’ scores are low in part because a disproportionately greater share of U.S. students come from disadvantaged social class groups,” they argue.
Stuff and nonsense, responds Paul Peterson in Education Next. The Carnoy-Rothstein studied ignored family income, which is just as high in the U.S. as in the comparison countries. It uses one factor to determine social class: The number of books 15-year old students estimate are in their home.
Only 18 percent of U. S. students say they have many books in their home; in the other countries this percentage varies between 20 percent and 31 percent. In the United States 38 percent say they have few books in their home. In the other countries, this percentage varies between 14 percent and 30 percent.
Students’ estimates of book in the home is a good predictor of student achievement, writes Peterson. But there’s a chicken-and-egg issue.
. . . reports of books in the home may be as much a consequence of good schools and innate student ability as an independent cause of student achievement. Students who find it easy to read are likely to report more books in their home, because they are more aware of them. Students attending an effective school are more likely to be good readers who are then aware of the resources at home. Countries that expect students to perform well on a national examination when they finish secondary school may induce higher rates of reading than countries that do not set clear standards for high school students.
Only 14 percent of Korean students come from few-book homes, compared to 38 percent of U.S. students, and 31 percent of Korean students come from homes with many books, while only 18 percent of American students do. It’s “bizarre” to assert that Korea’s upper class is nearly twice as large as in the U.S., and that our lower class is nearly triple the size of Korea’s, writes Peterson. The U.S. does not have a vanishing bourgeoisie and a vast proletariat.
The study encourages people to think that U.S. schools are just fine — except for inner-city schools, which face an impossible challenge because the kids’ homes are no good, Peterson writes. Good reading habits — which schools can do something about — “are much more important to achievement than family income and other measures of social class.”
