Several states tried to reduce class size, but generally class sizes have not been reduced and are increasing again.
So, does class size affect student achievement?
The New York Times featured a story about a week ago on class size creeping up in New York City; and now there are comments in the letters section.
At recent legislative hearings on whether to renew mayoral control of the New York City schools, lawmakers and parents alike have asked, again and again, why Mayor Michael R. Bloomberg and Chancellor Joel I. Klein have not done more to reduce class size. On Tuesday, the Education Department issued a report that found the average number of children per class increased in nearly every grade this school year.
“If you’re going to spend an extra dollar, personally, I would always rather spend it on the people that deliver the service,” Mr. Bloomberg said when asked about the report on Thursday, calling class size “an interesting number.”
“It’s the teacher looking a child in the eye, and teachers can look lots of children in the eye,” he added. “If you have to have smaller class size or better teachers, go with the better teachers every time.”
Is that even the issue?
Does class size matter? Can a great teacher teach 40 students in a class, 200 students a day, better than a mediocre teacher can teach a smaller number?
How could we possibly know?
