WASHINGTON — Emily Strzelecki, a first-year science teacher here, was about as eager for a classroom visit by one of the city’s roving teacher evaluators as she would be to get a tooth drilled. “It really stressed me out because, oh my gosh, I could lose my job,” Ms. Strzelecki said.

Her fears were not unfounded: 165 Washington teachers were fired last year based on a pioneering evaluation system that places significant emphasis on classroom observations; next month, 200 to 600 of the city’s 4,200 educators are expected to get similar bad news, in the nation’s highest rate of dismissal for poor performance.

The evaluation system, known as Impact, is disliked by many unionized teachers but has become a model for many educators. Spurred by President Obama and his $5 billion Race to the Top grant competition, some 20 states, including New York, and thousands of school districts are overhauling the way they grade teachers, and many have sent people to study Impact.

A cognitive neuroscientist, Ellen Bialystok has spent almost 40 years learning about how bilingualism sharpens the mind. Her good news: Among other benefits, the regular use of two languages appears to delay the onset of Alzheimer’s disease symptoms. Dr. Bialystok, 62, a distinguished research professor of psychology at York University in Toronto, was awarded a $100,000 Killam Prize last year for her contributions to social science. We spoke for two hours in a Washington hotel room in February and again, more recently, by telephone. An edited version of the two conversations follows.

Q. How did you begin studying bilingualism?

A. You know, I didn’t start trying to find out whether bilingualism was bad or good. I did my doctorate in psychology: on how children acquire language. When I finished graduate school, in 1976, there was a job shortage in Canada for Ph.D.’s. The only position I found was with a research project studying second language acquisition in school children. It wasn’t my area. But it was close enough.

As a psychologist, I brought neuroscience questions to the study, like “How does the acquisition of a second language change thought?” It was these types of questions that naturally led to the bilingualism research. The way research works is, it takes you down a road. You then follow that road.

Q. So what exactly did you find on this unexpected road?

A. As we did our research, you could see there was a big difference in the way monolingual and bilingual children processed language. We found that if you gave 5- and 6-year-olds language problems to solve, monolingual and bilingual children knew, pretty much, the same amount of language.

But on one question, there was a difference. We asked all the children if a certain illogical sentence was grammatically correct: “Apples grow on noses.” The monolingual children couldn’t answer. They’d say, “That’s silly” and they’d stall. But the bilingual children would say, in their own words, “It’s silly, but it’s grammatically correct.” The bilinguals, we found, manifested a cognitive system with the ability to attend to important information and ignore the less important.
