viz.

That's a good question. The article leads me to believe that the newer approach is supplanting the old one. For example, one of the writers of the comic book is quoted as saying,

There are no piles of bodies, because we knew from experience that this could block children from dealing with the whole subject. Also — and we had endless conversations about this — we decided not to show Hitler as a beast or inhuman because the Nazis, after all, were human beings. That’s the point. Anyone can be a perpetrator or a hero. The choice is yours.

But perhaps it's a matter of age difference: the comic may be for younger students, and other materials may be used in classrooms for older students.

I also like the MTV ads, particularly the subway one. There is something effective about the connection between these quotidian experiences and the Holocaust that is effective. But I'm not sure what response they would engender beyond a certain "Whoa..." At the Holocaust Memorial and Museum in Dallas, which I visited a couple of times while I was in high school, there is a box car that is believed to have been used to transport people to concentration camps. While being led through the museum, you are actually taken inside it, where you are asked to pause and (if I remember correctly) observe a moment of silence. That, I thought, was extremely discomforting, but also extremely effective.
