For those of you who are keen to teach "just the facts" of history and leave interpretation out of it, try the following description of the events of August 1945 (just the facts, with all interpretive statements edited out).
"On August 6, 1945, a single B-29 released an atomic bomb over the city of Hiroshima. Eighty thousand Japanese men, women, and children died as a direct result--burned to death or crushed in demolished buildings. The center of the city, a 1-2 mile radius around Ground Zero, ceased to exist. Three days later, a second atomic bomb did similar damage to the city of Nagasaki. An additional 40,000 Japanese died. Japan surrendered on August 15, and the instrument of surrender was signed on September 2, aboard the battleship Missouri."
Just the facts means just the facts . . . ideas that have been part of the "standard" explanation of the atomic bombings since 1945 (that they forced a surrender that was not otherwise imminent; that they forestalled an invasion of Japan; that they saved millions of lives; that they were legitimate payback for Pearl Harbor, or Bataan, or whatever) are all interpretative statements and are thus out of bounds in a just-the-facts approach.
So, too, for that matter are other statements central to many people's vision of US history:
"Lincoln saved the Union . . . "
"Reagan ended (or prolonged) the Cold War . . . "
"Ford's assembly line transformed business . . ."
"The Civil War was about [fill in the blank] . . ."
"The nuclear family was key to 1950s life . . ."
Virtually any statement about a person, institution, or event . . . beyond the most basic recitation of "this happened, then this happened" involves interpretation. Even "America is a great place to live" is not a fact, but an interpretation of a body of facts. Interpretation, if done intelligently, involves formulating ideas about the facts, testing those ideas against the facts, and choosing among competing interpretations--in short, "critical thinking."
I tell my students at the beginning of every term (and several times thereafter): "I don't care if you agree or disagree with me about how to interpret this or that event. . . I do care whether you can state your position concisely, develop it coherently, and (most of all) support it with evidence.
