In 1970, educator, linguist, researcher, and Jesuit priest Dr. John Bryde, documented an educational phenomenon among Sioux children on the Pine Ridge Reservation in South Dakota. He noted that the Sioux children began school primed to learn. They exhibited an aggressive curiosity about the world and strong confidence in their own abilities. During the first three to four years of school, the Oglala Sioux children tested out equal to or even slightly above their non-Indian counterparts. Then, something began to happen.
