My older son will do his homework then not hand it in. It has always frustrated me, until i started looking at breaking down the behaviors and teaching them one at a time. What an eye opener. First we had him write his homework in an agenda every day and have the teacher sign it. This was to get him in the habit of noting his homework before he left class.
Then he started checking off the homework in the agenda to get used to doing it all. Now we are working on the handing it in. They allow him in math to correct in class, take it home to fix any problems, and bring it back a second time to hand in. He was missing 9 homework assignments because if this, and had a 52% average. Nick just is not capable of keeping track of the homework that long of a period for that many transactions. So he now hands it in the day after it is assigned, no matter if he made errors or not. Better a 90% than a 0.
He also got in all the back work and now has an 82%, even though he still had 3 assignments due. This was all based on homework. He tests in the 90%'s. I do not understand why there are not other options for these kids. In real life, he just will take a job where all his work is in one place. He will not take work home abd back, or he will lose it. He can start learning to organize, but at this stage in his life school just isn't all that big for him. So either the school needs to build some incentive for him, or they need to come up with ways to meet the different needs of their students. Yes, the boys need to put in more effort, that is also true. However, when girls were behind (in a few subjects only) no one just told them to put in more effort.
As I have said before, I looked on the wall in our school hallway, and 75% of the top four students of every year, going back to 1926, were girls. I know because I counted.
