Public Schools beat private in math instruction!

Wow!

I found this article in the Education Policy Blog about a new study, and must share:
Are Private Schools Better Than Public Schools? New Book Says ‘No’

Teaching methods, teacher professional development, and other factors result in a better outcome in our public schools! And the favorable comparison applies not only to the charters, but to the bona fide private schools as well.

It is often assumed that private schools do a better job educating children than public schools, but a new book, “The Public School Advantage,” which is being published this week, shows this isn’t the case. Here’s a piece the authors, Christopher Lubienski, a professor in the Department of Educational Organization and Leadership at the College of Education at University of Illinois, and Sarah Theule Lubienski, professor of mathematics education in the College of Education at the University of Illinois.

We found that once we account for the fact that private schools serve families with more advantages associated with academic success—things like money and highly-educated parents—we find that public elementary schools are, on average, simply more effective at teaching mathematics. Indeed, demographic differences more than explain any apparent edge in the raw scores of private school students, and by the time they reach middle school, public school students score ahead of their demographically similar, private school peers, with differences ranging from a few weeks to a full grade level, depending on the type of private school.
