Inside a double-wide trailer on the Warm Springs reservation in central Oregon, nearly two dozen American Indian high-school students sit facing computers, teaching themselves math and history. Rain slaps the roof. Ear buds dangle from one girl’s left ear. Two more students whisper, sharing a joke. Still another student, his face set in a serious expression, stares at the screen before him. The one teacher in the room previously taught third grade; he’s certified to teach high-school continuing education and agricultural science. Nearly all of the young people who study in this trailer—officially called the Bridges Career and Technical High School at Warm Springs—are Native Americans.
