How can teachers effectively use documentary film to teach history, and toward what goals? This article addresses these important questions by: (1) exploring what we know about secondary teachers' practices with documentary film and secondary students' beliefs about documentary film as a source of knowledge about the past, (2) proposing a rationale for the use of documentary film that supports the goals of history education, and (3) discussing examples of documentaries that can be shown to further the rationale presented. Although there are numerous suitable purposes and methods for using documentary film, we argue that two of the most powerful and appropriate are as a way to explore multiple perspectives and as a way to teach about controversial issues.
