The HighScope Perry Preschool program, conducted from 1962 to 1967 in Ypsilanti, Michigan, was offered to African-American children from neighborhoods with low incomes. Teachers were certified with at least a bachelor’s degree, the average child-teacher ratio was 6:1, and teachers provided weekly, 1.5 hour home visits for all participants. The HighScope Perry Preschool model encourages active learning, where children plan their own activities, carry them out, and reflect on them. Adults arrange the classroom to foster learning in various areas and coach children as the children plan activities, solve problems, and think through their ideas. (author abstract)
