Dear god, by the time a kid is in grade 5 or 6 they've lost an hour a night to reading alone. In my experience homework was rarely of use - the in class practice was enough, and home time was for the fun you didn't have while in school.
In other words, they prioritize visible effort over achieved results.
After devoting so much time to education theater, do the kids even have any energy leftover to put into actual learning?
I hope your master wasn't in statistics, because you made a poor extrapolation from data.
I read because I loved it and was exposed to it at a young age from home, not because school required me to read.
What if, instead, schools simply set aside a chunk of time out of the school day for reading, maybe 15 minutes, maybe 30, and leave it entirely up to the individual kids to decide what it is that they read?
The homework is also very useful to have a chance to review topics and ensure understanding of things that maybe he missed in class due to not paying as close attention as he needed to.
It's been very gratifying to see his confidence levels improve and for him to start to self-manage his time or even decide to skip a scooter break because he was on a roll.
Clearly all of these are probably ancillary to the stated purpose of homework and are my own specific situation.
Thank you for being a case in point. It doesn't matter what else I do, (see http://bentilly.blogspot.com/2012/10/my-sons-flashcard-routi... for example), I can always be accused of being lazy from the peanut gallery.
I know some people are taking offense to your comment, but the reality is that even parents who very much wish to be involved in their child's education often need a nudge on what, exactly, to talk about.
Even parents who home-school their kids usually buy academic materials to use for this reason.
So mileage does vary on these things. By a lot.
I listed factors that will make homework harder for him. He is older, so more homework. A complex home environment, so harder to stay organized and consistent. More children, dividing parental attention. The more serious that ADHD is, the harder that staying on task becomes.
Put it all together, and homework becomes a lot bigger issue for him than it is for a normal child.
