Research That Benefits Children and Families: Uplifting Story

There are many topics that came to mind when thinking about what I would research.  When thinking about children in my class I came to the conclusion that would like to research children who are adopted and if it has any affects on their academics or behavior.  This comes to mind because I have one student who is adopted.  I don't know if he knows but in the beginning he was BIG trouble in the classroom.  As the year went on his father tried many different medicines because he was diagnosed with ADHD.  Well one finally worked but after a while he started hallucinating and acting weird.  He now sees a child psychologist every other week but he still has other issues.  He has anger issues and can't seem to let things go.  So I wonder if being adopted has anything to do with his issues.
