Joe Nystrom, who teaches math at a low-income high school here, used to think that only a tiny group of students — the “smart kids” — were capable of advanced coursework.
But two years ago, spurred by a national program that offered cash incentives and other support for students and teachers, Mr. Nystrom’s school, South High Community School, adopted a come one, come all policy for Advanced Placement courses. Today Mr. Nystrom teaches A.P. statistics to eight times as many students as he used to, and this year 70 percent of them scored high enough to qualify for college credit, compared with 50 percent before. One in four earned the top score possible, far outpacing their counterparts worldwide.
South High students said Mr. Nystrom and his colleagues had transformed the culture of a tough urban school, making it cool for boys with low-slung jeans who idolize rappers like Lil Wayne to take the hardest classes.
