From preschool parents to Pentagon chiefs, people are calling for more foreign language instruction. Factors driving the demand include China's economic growth, which has prompted the College Board to add Chinese to its list of Advanced Placement tests. Meanwhile, President George W. Bush, citing national security concerns, has called for the expanded teaching of languages not typically offered in public schools, including Arabic, Farsi, and Chinese. Also fueling interest are the growing ranks of "heritage" language students who are raised in homes where a language other than English is spoken. At the same time, more parents and schools are recognizing the value of preparing even very young children for life in a broad international community. In funding and implementing language programs, three questions policymakers and instructors often ask about foreign language learning and teaching are: (1) At what age should foreign language learning start; (2) What teaching methods should be used; and (3) To what extent is there a special aptitude for foreign language learning?
