I was wondering if you have found books for your research?
I am new learning about this I found some real eye opening info.

Teaching kids in the regular classroom - a gifted teacher went to a gifted seminar and learned a different approach. She pretested the kids on vocabulary and found they all score A. She then realized she had been teaching her gifted class much of what they already know.

I think it also says this is the same book.
Who learns the least in regular classrooms? the most capable.

This really hit home with me because my son is the top student in his class. He probally is the most capable and eager to learn and is getting less opportunity.

Please keep us updated. I would like to know the classes reaction when you present your report. good luck.
