At History's Doorstep is a partnership among the school district, Camden County College, Historical Societies of Gloucester City, New Jersey, and Camden, City of Gloucester City, and USS New Jersey to bring teachers, scholars and historical resources together in a professional development program for K-12 teachers. The project involves 3 training sessions in the fall and spring and 5-day summer institutes focusing on historical theories, oral history, genealogy research, educational technology and major eras and events in U.S. and local history. Topics such as Origins of the Civil War, Salem Witch Craze, Assassination of Abraham Lincoln, American Involvement in World War I, and Origins of World War II focus on critical analysis skills. Site visits illustrate colonial/revolutionary/underground railroad/Civil War and Reconstruction events. Other sites build understanding of the Spanish-American War, World Wars, Korean War, Vietnam, and the Cold War.
