Bilingual or Immersion? A New Group of Studies Is Providing Fresh Evidence That It's Not the Language of Instruction That Counts, but the Quality of Education

Article excerpt

Eight years ago, Proposition 227 virtually eliminated bilingual education in California's K-12 schools. Since then, the English-only approach has made inroads in states like Arizona and Massachusetts, where ballot initiatives have created even more restrictive "English immersion" programs than California's. In Colorado, backers of a failed ballot initiative are trying again, this time with a campaign for a constitutional amendment.

But a group of new studies is providing fresh evidence of what many researchers have been saying all along: English immersion has more political appeal than educational merit.

"We're saying it's not possible given the data available to definitively answer the question 'which is better--bilingual or immersion?'" says Dr. Amy Merickel, co-author of "Effects of the Implementation of Proposition 227 on the Education of English Learners K-12." The five-year, $2.5 million study was conducted for the state of California by the American Institutes for Research and WestEd.

"We don't see conclusive evidence that bilingual education is superior to English immersion, and we don't see conclusive evidence for the reverse," Merickel says. "We think it's the wrong question. It's not the model of instruction that matters--it's the quality."

Dr. Tim Shanahan, professor of curriculum and instruction at the University of Illinois-Chicago and director of its Center for Literacy, agrees.

Shanahan and a team of more than a dozen researchers from institutions across the nation recently completed a synthesis of all the available research on literacy, including second language literacy for the U.S. Department of Education.

"When we looked at all the past attempts to get at this issue and analyzed their data, essentially what we concluded was that, in fact, kids did somewhat better if they received some amount of instruction in their home language," Shanahan says. "How much? It was not clear from the available data. What should it look like? That wasn't entirely clear either. But across the board, the impact of some instruction in home language seemed to be beneficial.

"But one of the things that surprised me and that stood out for me was the sheer volume of the research that was not devoted to these issues," he adds. "If you look at the data, most of the research is on [which] language of instruction [is better]. That issue has so sucked up all the oxygen that all those other issues of quality clearly are being neglected."

Such conclusions run sharply counter to the assertions of many defenders of English immersion. In 1997, millionaire Ron Unz began a campaign against bilingual education, forming an advocacy organization with a simple name and message--English for the Children. That organization helped push Proposition 227 to a landslide victory in California, claiming 61 percent of the vote. Two years later, citing dramatic gains on test scores for immigrant children, the English for the Children movement moved to Arizona, where Proposition 203 notched 63 percent of the vote. In 2002, Massachusetts followed suit with Question 2, which was passed with 70 percent support. But in Colorado, voters rejected the English-immersion philosophy, turning it down 55 percent to 44 percent at the polls.

But the movement began to fizzle after 2002. The offices of English for the Children have closed, and studies have consistently been punching holes in core tenets of the English-only argument.

First to fall were the "dramatic gains" in test scores. Proponents of English-immersion stated emphatically that test scores for immigrant students had shot up 40 percent between 1998 and 2000. But research teams from Stanford University, Arizona State University and others pointed out that scores had risen for all students during that period. They also noted that the rising test scores were due to the fact that California had introduced a new achievement test and not to the effects of Prop 227. …
