The Center for Environment, Economy, and Society (CEES) has developed an Integrated Ecology Curriculum (IEC) implemented in 5 NYC public middle schools serving over 1,000 students. The IEC focuses on hands-on field investigations to teach science and other subjects in an integrated way. It has led to significant decreases in truancy, suspensions, and course failures along with increases in standardized test scores. The IEC provides authentic learning experiences, develops students' higher-order thinking skills, and increases engagement—benefiting students academically and personally.
