From the Announcement:
The Roy Rosenzweig Center for History and New Media (RRCHNM) is proud to announce the launch of Understanding Sacrifice (abmceducation.org/understandingsacrifice).
Sponsored by the American Battle Monuments Commission (ABMC), this website is part of an 18-month professional development program for middle- and high-school teachers. Working with National History Day and RRCHNM, 18 teachers are developing interdisciplinary lessons about WWII in Northern Europe. They are also researching the life of a service member buried or memorialized at an ABMC cemetery. The resulting profiles will be incorporated into the lessons.
