This professional development program targets 8th and 11th grade U.S. teachers in low-performing schools in a 143,000-student district. Its thematic framework-"what does it mean to be a good citizen in different periods of American history?"-is based on The Good Citizen: A History of American Civic Life, by Michael Schudson (Harvard Univ. Press, 1998). Two summer institutes each year and 8 academic sessions during the school year dealing with content knowledge and instructional skills are combined with creation of teacher teams and opportunities to observe colleagues' classrooms. The LEA's partners are the University of California, San Diego's Department of History and California History-Social Science Project CREATE, Preuss School, San Diego Museum of Art, San Diego Public Library, and Center for Civic Education. Content covers the American Revolution to the early 20th century, and continuity and change in the 20th century, including civil rights, the World Wars, industrialization, and immigration.
