A growing number of persons in the United States speak languages other
than English, and there has been confusion about approaches to langua
ge teaching/intervention and to education in general among this hetero
geneous group. While early research indicated that bilingualism might
have possible deleterious effects on child development, in later studi
es, bilingualism has been associated with cognitive advantages. This a
rticle discusses the concepts, principles, and practical application o
f serving children who live in bicultural households; explores possibl
e reasons for the delays identified in these children; and offers a po
pulation-based approach to intervention with them, using a case study
example. Developmental screening of children who are military dependen
ts living in South Korea, many of whose parents speak two different la
nguages (one Korean and one American English), revealed a high prevale
nce of risk for language delay. A solution is proposed that addresses
both language and cultural identity and that does not isolate children
or promote ethocentrism.
