Within the field of social studies education, disciplinary models of teaching, such as approximating a historian in asking students to "think historically," have been the emphasis of countless professional development and teacher education programs. This movement, however, has focused largely on the use of traditional primary documents and generally does not include training for teachers or students on how other forms of media construct history. This collective case study examines how two US history teachers' epistemological beliefs about historical media and ideology and overall goals for students as citizens impacts their pedagogy with different historical media, particularly film. Data were collected on a daily basis over the course of six months, and included observations, teacher interviews, and the media used as historical sources. Findings show that teachers' beliefs about how sources represent history affect their pedagogy with the particular media, and that epistemic development and current notions of historical thinking may be limited when it comes to media that commonly serve as historical sources for the public at large (e.g., film, television, WWW, videogames). This limitation is caused in large part by the teachers' larger goals for students that are informed by their ideology, and difficulty in identifying bias in media that aligned with their own beliefs. Therefore, a shift in teachers' epistemic beliefs about how different forms of media serve as sources of history, essentially a form of critical media literacy, and coinciding recognition of ideological goals needs to occur in order to better instill students with skills in historical and media literacy for the twenty-first century.
