ECHO II is a collaboration of the Southeastern and Santa Fe Trail BOCES with the Adams State College Departments of History, Government, and Philosophy, Old Bent's Fort National Historical Site of the National Park Service, Colonial Williamsburg, and the Organization of American Historians. ECHO II will improve student knowledge of basic U.S. history by providing elementary and secondary school history teachers with continued professional development. Through Freedom Trail field trips, workshops, and one-week annual graduate-level summer institutes, as well as through follow-up lectures and site visits by local historians, teachers will: (1) enhance their knowledge of traditional American history content and methodology; (2) become part of a community of local historians; (3) develop a network of resources; and (4) create learning strategies for applying their new knowledge and skills in the classroom. Program content will span American history from the Colonial Era through the Cold War. Content emphasizes the use of primary sources and connections between national and local historical events. Participants will select specific topics for examination.
