eJewishPhilanthropy has an op-ed from Rabbi Benjamin Berger,senior educator at the Ohio State University Hillel who used the Hagadah and seder format to teach about the Holocaust.

The activation of memory rather than the telling of history is the next component of the seder that make it a unique educational experience. Memory is personal and like the exodus, the Holocaust demands that we personally live as if we were there, even if for a moment.
