Degrees and Certifications
Carl earned his Ph.D. in Educational Policy Studies from the University of Wisconsin-Madison, where he focused on comparative history of education.

He is most interested in the history and politics of urban education in the post-World War II era and the nineteenth and twentieth century origins of mass schooling in North American, European, and Asian contexts. His interest in urban education reform movements in the aftermath of Brown v. Board resulted in numerous publications on school vouchers, mayoral control, and parental choice; among them a book entitled Freedom of Choice: Vouchers in American Education (Santa Barbara, CA: Praeger, 2011). More recently, he has developed an interest in the explosive growth of mass schooling and higher education in China.
