OP, I have a son (my youngest) like you've described, although we didn't have the disrepectful issue at home.
First, I had him tested to rule out any medical problems (and there were none.) He's a senior this year and school and homework have always been a battle. He just hates it. If I had it to do all over again, I would homeschool. He does really well with hands on learning or something that interests him.
An example, each year we take a big family vacation. In September/October of each year I give the kids (we have 4) a budget and they each plan a family vacation within that budget. They pick where they want to go, what there is to do, where to stay, etc. On Christmas morning each child makes their presentation and we vote (with Mom and Dad having the final say). He has no issue researching places, finding out what there is to do, doing all the math, etc. He's actually put together some really elaborate presentations over the years with videos, music, etc. It interests him and he excels with it. But, if I were to say I want to do a research paper on Costa Rica (one of his choices one year - and we ended up going) it might get done, but poorly. Given his choice of place and presentation he ended up doing this elaborate presentation about the people, the language, the food, the differences in geography from staying inland to on the beach, the cost differences from staying in various areas. He got really involved in it and even researched their history, what they major imports and exports were, etc. He became a walking, talking encyclodpedia about Costa Rica that year. For him, learning is about how the subject is learned and a traditional school system doesn't foster that.
Good luck.
