摘要

Every year Britain's school-children provide gratifying evidence of their increasing smartness. More leave primary school having done well in tests of reading, writing and arithmetic; more get top grades in national exams at ages 16 and 18. Nay-sayers, though, think this progress overstated, even illusory. They attribute rising marks to dumbed-down curricula, downward-drifting grade boundaries and teaching to the test. But even the gloomiest assessment, it appears, may not go far enough. In important ways, the country's children appear to be becoming dumber.rnMichael Shayer of King's College London has been testing children's thinking skills since 1976, when he and colleagues started studying the development of reasoning abilities in young people. In 2006 and 2007 he got 14-year-olds to take some of the same tests as 30 years earlier. The findings, to be published early next year, are sobering. More than a fifth of youngsters got high scores then, suggesting they were developing the ability to formulate and test hypotheses. Now only a tenth do.
