I need help in applying the principals of positive discipline in an after school setting with at risk children that are 8 to 11 for the most part. Some are from homes where corporal in the norm and one or two may be from homes where the adults are violent with each other. Most come from homes where they are supported but the destructive behavior of a few hurts us all. Unfortunately, these are the children we are trying most to reach. When they refuse to follow clear guidelines, it doesn't seem fair to anyone.
