This study is to investigate archival use behavior of history teachers in high schools. The study conducted 3 times interviews with high school history teachers and carried out a survey on recognition of archives, archival use, archival seeking behavior, and barrier factors for archival use to 30 teachers from the 2 local communities of history teachers. According to the survey, history teachers have used archives for raising the historical understanding by students in their classes. But the tight curriculums of history and the lack of time to search archives were barrier factors for teachers to use archives in their classes. The teachers who participated in this survey suggested that integrated DBs of archives in Korea and source books with commentaries need to promote use of archives in history classes
