How is the Holocaust taught in schools? How do students make sense of this challenging subject? How are people affected by visits to Holocaust memorial sites? Empirical research on teaching and learning about the Holocaust that tackles these and other questions has grown rapidly over the past fifteen years, a period marked by the professionalization and expansion of the field. In 2013, the International Holocaust Remembrance Alliance (IHRA) decided to carry out a study to establish a picture of this emerging field of research. A multilingual expert team mandated to collect and review research in fifteen languages identified nearly 400 studies resulting in more than 600 publications. Three years of work resulted in this book, which carries the field beyond anecdotal reflections and moral arguments. This systematic review includes research conducted in most IHRA Member Countries as well as several non-member countries. The multilingual focus of the project enables cross-cultural analyses and the transfer of knowledge between various regions and countries. The book’s two parts present the research by language and by selected themes. This innovative transnational, translingual study reflects IHRA’s core mission: to shape and advance teaching and learning about the Holocaust worldwide.
