Missing from the Times' otherwise informative article about bilingual education in California ("Californians, Having Curbed Bilingual Education, May Now Expand It," Oct. 17) is a response to Ron Unz' serious accusation. Unz correctly emphasized the importance of English but made the false claim that bilingual education prevents English language development.
The opposite is true: Study after study has shown that children in bilingual programs do better in English reading than similar students in all-English “immersion” programs.
In the most recent analysis, Researchers Grace and David McField examined all available studies comparing bilingual education and English immersion. They concluded that when both program quality and research quality are considered, the superiority of bilingual education was considerably larger than previously reported.
Bilingual programs, when set up and evaluated correctly, do not prevent the acquisition of English, they accelerate it.
