Defining bilingual education and what the research really says about it: A response to Izumi
Thursday, June 19th, 2008Lance Izumi defines bilingual education as teaching core subjects in the first language. This certainly happens in early stages of bilingual education, but in bilingual programs students are taught subject matter in English as soon as it can be made comprehensible. Having some instruction in the first language helps this happen, as it gives students background knowledge. I prefer this definition of bilingual education: The use of the child’s first language to accelerate English language development.
Contrary to Izumi’s view, outlined in “Remembering Prop. 227 and the ‘End’ of Bilingual Education” (June 18), research has consistently shown that dropping bilingual education in California did not improve English language development. Also, controlled studies consistently show that bilingual programs are more effective than English immersion in helping children acquire the English they need for school.
I have reviewed this evidence in a professional paper, “Proposition 227 and Skyrocketing Test Scores: An Urban Legend from California,” published in Educational Leadership, 62(4).
