Winnetka, << wuh NEHT kuh, >> Plan is a teaching plan designed to provide individualized instruction. It was developed in the public elementary and junior high schools of Winnetka, Illinois, after World War I (1914-1918). It influenced widely the growth of the progressive education movement. According to the plan, teachers deal with each pupil individually so that pupils can develop their own particular abilities at their own rate of speed. Pupils work alone in their regular studies, but take part in many group activities in which their achievements are not measured.
