Now that we are nine years removed from September 11, 2001, this is something I’ve wondered: how do schools teach about this day? According to the Christian Science Monitor, there seems to be a variety of approaches.

Another place to look would be school textbooks. With evidence that textbooks either just plain get it wrong or present biased perspectives, how younger generations learn about 9/11 will be something to watch.

Overall, both specific school lessons and textbooks will help shape the American collective memory regarding the event. This collective memory can take time to develop and is likely to be controversial; just look at how long the 9/11 memorial is taking to shape up at Ground Zero.
