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 who we are and where we are without history, much less 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 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. 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.
