How to manage unruly student who is ruining team

[BulldozerChick]

Thank you all for taking the time to share your insights and advice. It's not my intention to violate a trust-I was just desperate! I am not a school, so no support from there. I did kindly ask the mom to attend, so that it could be a positive and learning experience for child and all participants. She said ok and showed up. No problems! Next meeting, she dropped him off and it was a disaster. In hindsite, I should've called her and asked her to come back. I did reiterate the need for a parent's presence at tonight's meeting, but haven't heard from her. This makes me sad because I think FIRST programs are great for outside-the-box kids, but hadn't been prepared for this. I appreciated the understanding and encouragement to talk to the parent in the first place. I liked the idea of giving him a task to be in charge of, which worked with his mom there.

Curious-at workshops outside of the season, do any FIRST programs have sessions on handling group dynamics? Any good references? Thank you!!
