I worked with an ED student last year who did not know how to interact with others without lying or manipulating. This student had major issues besides lying, but where the lying was concerned I did the following:
1. Praise that student (on the rare occasion that it happened) and others for honesty.
2. I questioned stories that I thought may not be truthful and even called home to check them out. EVERY time I caught the student in a lie, they had a consequence.
3. If the student began a story that I knew (or strongly suspected) was not true, I would interupt and say "If this story is not true, I don't want to hear it."
I know these methods may seem a little extreme, but these things did help make the child aware of their behavior. It's really sad when a child becomes so involved in their lies that they can no longer really tell what is the truth and what is not. As far as what became of the child later on. . .like I said, the child has A LOT of issues - last I heard, they have been sent to an alternative school, a pshychiatric (sp?) hospital and now a residential placement. I think of this child often and hope that the impact that I had will at least make a small difference. . .
