I don't see the value in continuing to present ideas, etc. to the board if this continues.
First, this needs to stop here. The open discussion that needs to happen is your fustration that an idea was presented, you were given a lukewarm reception, darm near a "No" and then learn the next day that it's going to happen but we are going to do it this way. NOT COOL but happen more often than support groups have meetings for it!
Have you spoken with the teacher involved with this to see how you can help and where the idea came from? What I'm looking at is the damage is done. What I am helping you do now is show them how you can rise above this and see where you can help or offer info and go to the next thing.
Our HS student council came up with idea of haveing a dress down day. For a $1 students and teachers could wear jeans on a designated Friday as a break from the uniforms. Went over HUGE, so huge that the next year the former principal thought, if they can earn thousands then why not let EVERYONE Have a shot at this day. So instead of letting the Student Council still have one or two dress downs, she took the entire idea away and used it for the school's budget! At the time we had about 150 kids in our very small high school but that was enough to dampen things. Now they sell candy and telegrams but have never seen the money they did with that one idea. What did they do? With their advisors, they let the former Principal know they were upset and felt betrayed . THey understood this happens with great ideas but wished she had talked to them and treated they with the respect that she disires from her students. She did apologize....but didn't change anything.
Me? I would bring all the research I have done in regards to the Science Fair and infront of the Board and P hand it over to the teacher or volunteer and say, here's all that I have done on this glad to help, would have loved to seen it through but oh well.
You know, to hav an idea stolen is really a compliment...somehow it really is!
