True--today WW2 is like ancient history to most kids--and teachers.
I used to live in central NJ. Our school district was in an area of many retirees. The schools had a program of having WW2 vets and Holocaust survivors come in to speak to classes in the intermediate and high school history classes.History become very real to the kids, and the speakers told of things they had not talked about for fifty or more years, becasue it was important that their stories not die with them.
Also, because Veterans Day was not a holiday, our town would bus in, on a rotating basis, a couple of classes to attend the Veterans Day parade. The vets who marched really appreciated that--and the kids got to see real members of the Greatest Generation.
That's wonderful! Really puts a face to the history for the kids.
The shame is nowadays the same veterans etc would not be welcome in a lot of schools (not all schools, but in many, with all the other curriculum, that just wouldn't be 'important')
