Conflict Resolution and Kids

I found this article on conflict resolution and kids and really liked it.  I think the author highlights a problem many families face, which is they do not help their children understand that conflict is natural and help them to find positive ways to deal with the conflict.  I know that when I was growing up, I rarely observed my parents resolving conflict, it was hidden from me.  As an adult I had to come to understand that if someone raises their voice, it is not always a bad thing.  What do you think?  What did you learn as a child?
