Too many issues are contained in this quote, but I'll try to address them as they come up, so pardon me for breaking it up into smaller bits and pieces.
"But the quarrel over curriculum is in the end a quarrel over fault."
Fault is determined by the jury, and the jury is the student body. If the teacher makes a good argument, the kids will buy it. If the teacher is bogus, the kids will out the truth but only if the relevant facts are presented. A clever teacher can manipulate facts to meet a predetermined conclusion, much the same way as a clever trial lawyer can win a case on weak evidence and a strong closing argument - one that can be based on the evidence and presented in a pattern that would be reasonable to the person hearing it. I haven't found a teacher yet that could explain the reason why America was in Vietnam for 11 years, but I did find one that could explain why the Vietnamese communists fought the Japanese, the French, and the Americans for so long. Vietnam wasn't a Japanese homeland, it wasn't a French homeland, and it wasn't an American homeland.
"It (the quarrel over curriculum) seeks judgment about who's really to blame for terror, so it (the quarrel over curriculum) treats teaching as an exercise in persuasion—which is why it (the quarrel over curriculum) misses the point. An education shouldn't just prepare kids to be swayed by your talking points or mine. It should prepare them to live as citizens, to know how to act as voters, leaders, neighbors. "
True history is dates, times, numbers, events. On September 11, 2001, Tuesday, 2 commercial passenger jets were purposely flown into the World Trade Center with great loss of life. Not much argument there. How history is analyzed is up to the person making the argument one way or the other. The trick is knowing which way the speaker is leaning. Most students, from K-12, will buy whatever you tell them. Intellectual authority usually won't get questioned until college age. An education is being able to take true history, analyze it, and form a coherent opinion.
"And the best way to do that, after something like 9/11, is not to rehearse the emoting and posing of the culture wars but to give children practice facing, and making, the world that 9/11 gave us."
This last bit completely lost me. What was the point here? I think the author lost her train of thought and got swept up in the emotion of the moment. Either that or there was one more sentence that got cut off. I'm guessing that what the author wants is for teachers to simply state the facts and let the kids argue the benefits of an islamic jihad against the western nations. The problem with that approach is that history becomes a giant statistics table of numbers with no mouth - nobody to explain the significance of it all. Numbers are boring by themselves.
The best history course I ever took was taught by a community college professor who dealt with history not as a giant timeline, but as concepts that repeated over and over again. For example, the concept of a cult of personality: Julius Caesar, Charlesmagne, Josef Stalin, Adolf Hitler, Mussolini, John F. Kennedy, MLK. We spent 3 class sessions talking about it, interpreting it, arguing it, understanding it. Religion and government: The Crusades, The Inquisition, the Salem Witch Trials, nation of Israel, Lebanon civil war, the Aztec and Incas, Jesse Jackson, Louis Farrakhan. And his tests were always essays and you had to call out specific examples to support your interpretations.
I wonder what he'd think about the WTC and the collapse of the Taliban government. Ok, that'll be our topic for the next class!
