Interesting article in the New York Times by Motoko Rich on why it seems to be more difficult to raise reading scores than it is to raise math scores. I don't have time to discuss this in depth, but I will say that having taught math, English and  reading, I always found math to be the easiest subject to teach. By comparison I never felt I had a handle on the best way to teach language (or even if there is a best way).

That said, these are all excellent points:

Teachers and administrators who work with children from low-income families say one reason teachers struggle to help these students improve reading comprehension is that deficits start at such a young age: in the 1980s, the psychologists Betty Hart and Todd R. Risley found that by the time they are 4 years old, children from poor families have heard 32 million fewer words than children with professional parents.

By contrast, children learn math predominantly in school.

“Your mother or father doesn’t come up and tuck you in at night and read you equations,” said Geoffrey Borman, a professor at the Wisconsin Center for Education Research at the University of Wisconsin. “But parents do read kids bedtime stories, and kids do engage in discussions around literacy, and kids are exposed to literacy in all walks of life outside of school.”

Reading also requires background knowledge of cultural, historical and social references. Math is a more universal language of equations and rules.

“Math is really culturally neutral in so many ways,” said Scott Shirey, executive director of KIPP Delta Public Schools in Arkansas. “For a child who’s had a vast array of experiences around the world, the Pythagorean theorem is just as difficult or daunting as it would be to a child who has led a relatively insular life.”

Education experts also say reading development simply requires that students spend so much more time practicing.

And while reading has been the subject of fierce pedagogical battles, “the ideological divisions are not as great on the math side as they are on the literacy side,” said Linda Chen, deputy chief academic officer in the Boston Public Schools. In 2011, 29 percent of eighth graders eligible for free lunch in Boston scored at proficient or advanced levels on federal math exams, compared with just 17 percent in reading.
