That's just over 6.5 million per school. Think how small the class sizes would be with that type of money.
Can you cite any peer reviewed controlled studies that show that "smaller classes" improve student performance in any measurable way?
That smaller classes are "better" is something that everybody "knows", but you would be astonished at how little actual evidence there is. The few studies that have been done have produced mixed results. Kids from disadvantaged backgrounds can benefit in early grades. But brighter kids actually do worse in smaller classes, since it is harder for them to read ahead rather than follow along at the pace of the slowest kid. Some studies have found that much of the benefit is not that the classes are smaller, but that they are quieter. So some soundproofing might do more good than hiring more teachers.
The best performing schools in the world are in East Asian countries such as South Korea, Singapore, and some cities in China. They typically have class sizes more than twice that in America.
