Several days after the Tucson Unified School District's board voted on Jan. 10 to dismantle its Mexican-American studies classes...Chicano-literature teacher Curtis Acosta—a finalist for the UA Circle K Teacher of the Year award—talked about how the changes were affecting his classes..."We're filled with the vagueness that the law is founded upon," Acosta said. "No one knows what to tell us definitively." Acosta was told to switch his junior and senior level classes from Chicano literature to English literature, and that he can no longer teach from books like Luis Alberto Urrea's novel The Devil's Highway; Bless Me, Ultima by Rudolfo Anaya; or Mexican WhiteBoy by Matt de la Peña.
