Being a military child overseas, you go to the local schools of your country or a DODEA (Department of Defense) school if one is available. Saying this they kids get a lot of world or host country history and little to none of US history.
My mom for the longest time (and probably still does) thinks that these kids should be getting US History as they are Americans and they need to know about their own country. I have tried explaining to her that at some time in their education whether it be in high school or university that they will get some type of US history and if not, it is not a big deal. If they are interested in US History that they can do research, go online, read books and watch documentaries. Though my mom has not brought this subject back up in a few years, I know she really wants the kids to get educated on the history of our country.
On the flip side, my kids have been to wonders of the world (Pyramids of Egypt, Taj Mahal) climbed the Leaning Tower, Eiffel Tower, Mt Ararat in Armenia, tracked the North Pole, hiked the castles of Germany & France, swam in the Congo river- seen things and experienced things most people have only read about in the history books. They have met world leaders (the Dalai Lama in Paris to Senator Hillary Clinton in Armenia), sat at the dinner table with US Ambassadors and International Diplomats and played in the jungles of Africa.
My kids may never be US History buffs or the next US Senator, but these kids have seen the world, traveled to 66 countries, been in all types of environments and learning by travel. This is something that history books cannot give our children. They are living the history one step at a time.
