Here are my suggestions of books that might sway her parents;
�The Myth of Laziness� by Mel Levine, M.D.
�Right Brained Children in a Left-Brained World� by Jeffrey Freed, M.A.T. and Laurie Parsons
�Coloring Outside the Lines� by Roger Schank, Ph. D.
If private school is a financial option, you may consider requesting information be sent to their home. Often you can do this right on the website.
My nephew is in a similar situation. His ITBS scores are quite high and he earns all As (currently in 4th grade). His parents dismiss the gripes of other parents that his current, fun and popular teacher lacks rigor in the classroom. I�m also concerned that under-achievement will begin in middle school since he doesn�t seem to think school work is worthwhile.
