The embattled director of the Mexican-American Studies program in Tucson has been awarded the 2012 Myles Horton Education Award for Teaching People’s History from the Howard Zinn Education Project. Sean Arce is receiving the award at a time when his job is on the line. The city of Tucson school board will vote on Tuesday on whether to renew his contract. Tucson’s Mexican-American Studies program has been under attack following the passage of a bill which prohibits schools from offering ethnic studies courses.
