The purpose of this study is to see how historical films in history education can contribute to developing students' critical thinking about sources, historical consciousness, and various aspects of the uses of history. I showed a sequence of the film 1917 which is about the First World War, to a class of high school students who then worked on an assignment connected to the film and the purpose of the study. The material consists of 13 student responses to the assignment which contains three different questions where each question is designed to develop the theoretical approaches of source criticism, historical consciousness, and uses of history. The method is a content analysis with mainly a qualitative approach but also a quantitative approach with one coding scheme to each theoretical approach. The result of the study shows how the students’ reasons and discuss source criticism, historical consciousness, and uses of history towards the film sequence to develop their learning.
