     Why should I teach my children history? That sounds like a stupid question to even ask. But, as I hear

different home schooling teachers discuss history, I get the idea that there may be different reasons for

teaching history. Let me briefly explain the three good reasons for studying history and two bad reasons

for studying history.

     The major reason I see for studying history is that we can learn from the past. I am convinced that the

world would be a much better place if more people understood the successes and failures of the past and

the things that made these successes and failures. However, as the unfortunately true statement goes "the

one thing we seem to learn from history is that we don't seem to learn from history." Perhaps at least in

teaching history, to my children I can do a small part in changing this.

     A second major reason for studying history is that it is hard to understand the current political climate

in the absence of an understanding of its historical context. We can- not even understand why we are and

where we are without history, much less (更不必说) try to figure out where we are going or how we

should get where we want to be.

     I teach my children history, for one more reason. I purchased a set of historical audio (录音机) tapes

for our children. My seven-year-old son listened to them over and over. It was my hope that he would

become inspired by the accomplishments of people like the Wright brothers to accomplish things by

himself. I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr.

if, in doing so, young people are called on to stand for the principles that he stood for and accomplish what

he accomplished. I also think that by studying people like Adolph Hitler, people can learn to stand against

the things that he stood for.
