The six apps reviewed here exemplify best practices in the nascent field of Holocaust education apps, particularly those that illustrate a constructivist approach, one that places students at the center of the educational experience and encourages active learning. Interacting with survivors in the classroom and online has provided students with this opportunity until now, but as the witnesses pass away, teachers can turn to digital technology to offer another form of interactive engagement. Designed for today’s generation, these apps reflect our awareness that knowledge is constructed from and shaped by experience.
