In the Navajo culture, teachers are revered as "wisdom keepers," entrusted with the young to help them grow and learn. This is how Tia Tsosie Begay approaches her work as a fourth-grade teacher at a small public school on the outskirts of Tucson. Begay, one of our elementary education graduates and a current grad student in our educational leadership program, was named one of National Public Radio's 50 Great Teachers.
