Presentation

I have begun to work on my presenation. What is interesting is how my project has turned out. I am very excited to share with my fellow researchers how my project helped not only my students but myself. I believe that through sharing the results of this project, I can demonstrate that phone calls home can be for the positive and negative.
On a side note, I had a conversation with a parent yesterday morning. She was worried about a situation that took place on Monday. During our conversation she stated that I could use her name as a threat to her son. She began assuring me that telling him that I would be calling her would be a wonderful way to get his attention. Also, she would be more than welcome to come to school and discuss with him the problem that he is having.
I am a bit disheartened by this convesation. I have worked very hard on using the positive for his communication and progress in the classroom. I think that if I change to communicating more of the negative with the mother that her son may revert to some of his old ways. I then am led to think that there has to be a happy medium with the type of communication.
If there is this conversion of the two types communication (positive and negative) would they cancel each other out or would the positive to continue ot outweigh the negative?
