Tablets of learning

摘要

MORE than 250m children in developing countries are not in school. Those who do attend often fail to learn anything. According to one study of seven African countries, primary-school pupils receive less than two-and-a-half hours of teaching each day; teachers are absent from class about half of the time. Even when they show up, theirs is a Potemkin pedagogy, lecturing to nonplussed pupils. Only about a quarter of secondary-school pupils in poor countries would reach the basic level of attainment on standardised international tests.
