If teachers are to teach the Holocaust appropriately and empower students to become reasoned, compassionate, and critical citizens in the 21 st century, they must include Holocaust denial in lessons and units covering that topic. This inclusion is an important but often overlooked component of broad-based Holocaust education units.

This could assist teachers with delivering a more responsible Holocaust unit and better prepare students for the unique characteristics of 21 st -century research.
