Apache students comprised approximately 85 percent of the total enrollment of the Fort Thomas, Arizona, school system. The goals of the 1965-68 Diverse Capacity Project conducted in the school system were (1) to understand cultural differences between Indians and Anglos, (2) to identify the problems of Indians in an Anglo-oriented school, (3) to modify the traditionally oriented textbook curriculum, and (4) to establish a satisfactory instructional organization to meet the needs of both children and teachers in the rural school setting. Teaching techniques such as a directed reading activity, a unit approach, and a non grading level organization were employed. The results were later evaluated with the use of achievement tests, which showed that Anglo achievement was significantly superior to Indian achievement. Some conclusions were: (1) teachers of non-achievers are more inclined to find fault with the instructional program than with the children; (2) schools must involve all teachers in curriculum planning and selection; and (3) instructional programs must have greater priority over organizational plans. Achievement and attendance data are included. (CM)
