Two shaky theories dominate the debate over bilingual education. The facilitation hypothesis predicts a long-term advantage for bilingual education over all-English instruction. The time-on-task hypothesis predicts that all-English instruction is superior to bilingual education in teaching English. The data contradict both theories. Bilingual education programs are superior to all-English instruction in the early stages of learning English.
