Community School District in Waukegan, Illinois, proposes a three-year professional development program for middle and high school American history teachers. The district will partner with Lake Forest College, Lake Forest, Illinois, as well as The Chicago Historical Society, Loyola University Chicago and Northwestern University. At least eight different school districts in Lake County, Illinois, will participate in the program. In all, a total of 40 teachers are expected to participate. The project will include two summer institutes, two one-day symposia, continuous small Saturday workshops, and regular class visits. The project aims to raise student achievement by improving teachers’ knowledge and teaching strategies and by developing a cohesive model of professional development for grade six through twelve teachers of American history.
