My son is a bright and capable 4th grader who likes to put as little effort as possible into things. He's tried lots of sports and other activities and stays interested until it starts to get difficult, then he's ready to quit. He's been taking piano for a little over a year now and wanted to quit after a few months but I wouldn't allow it. He is doing well and I don't want him to think it's okay to quit something just because he thinks it's "hard." I insist that he practice every day and I sit next to him so that I can help him with his lessons (I'm not a great piano player but I can read music and can tell if he's playing something correctly or not). The problem is that he gets so angry with me when I correct him that he will often storm off in a horrible mood or else delay and goof off so much that what could be done in 15 minutes usually takes 30-45 minutes and ends up with us both exhausted and stressed. He understands how to read music and can play beautifully when he wants to, but most of the time he just wants to get through the lesson as quickly as possible and will practice things incorrectly just to get done. I know that practicing daily and practicing correctly are very important, and I don't expect perfection - I would just be thrilled if he would give his best effort for 15 minutes without fighting. Occasionally I try to let him play without correcting him at all, which only works when he corrects his own mistakes (which he sometimes does), but most of the time it seems to me that he is not trying to do his best. This applies to other things as well, but since he is supposed to practice the piano daily, this is almost a daily problem. Any suggestions?
