I'm sorry to say that most teachers don't receive much instruction about ADHD when they are learning to become teachers. Two good books that can help your teacher to learn more about ADHD if she wants to would be the Problem Solver Guide for Students with ADHD by Harvey C. Parker and How to Reach and Teach Children with ADD/ADHD by Sandra F. Rief. She can also get good information from the website (http://www.chadd.org) for Children and Adults with Attention Deficit Disorders.
