NYU professor and former charter-school-supporter-turned-critic Diane Ravitch tells KUAF’s Ozarks at Large reporter Jacqueline Froelich that Arkansas’s experience with segregation should be a lesson in what’s wrong with having two school systems — public schools, which must educate all comers, and public charter schools. Even Gary Ritter, head of the Walton-backed Department of Education Reform at the U of A, says it’s a problem that charter populations seldom include children who live in poverty and dysfunctional families. Times senior editor Max Brantley is also part of Froelich’s interview, aired yesterday on KUAF. Listen here.
