A Class Divided (1985)
"One day in 1968, Jane Elliott, a teacher in a small, all-white Iowa town, divided her third-grade class into blue-eyed and brown-eyed groups and gave them a daring lesson in discrimination. This is the story of that lesson, its lasting impact on the children, and its enduring power thirty years later."
