As a middle and high school history and social studies teacher, I have taught about the Holocaust and other genocides for many years. At the beginning of my career, students in my classes would have encountered only the Holocaust, but, recently, I have broadened my curriculum to include many additional examples and aspects of genocide. Despite growing efforts to expand the field of genocide education, there is still a gulf between academic scholarship and curriculum and practice within secondary classrooms. Scholarship, often inaccessible for secondary educators, is slow to make its way into course content. Understanding Atrocities: Remembering, Representing, and Teaching Genocide (2017) is the latest among recent efforts to bridge this gap and recognize the role of educators at all levels and community organizations in conversations about genocide education. This collection expands the conversation to include many voices, especially concerning the teaching of genocides other than, or in addition to, the Holocaust.
