Our corporation hired a firm to do a study, found that younger children performed much better during earlier hours, and flipped the schedules. The next year, the high school started at 8:50, and the elementary school at 7:45, and the schedules have been essential unchanged since. I can't describe how much of a difference that 1.5 hours made to a 16-year old.
As a father of 3 young children, they rarely sleep past when I have to wake them for school anyway. The same is definitely not true of teenagers.
Kids are different, and we really don't have very good ways of dealing with that in some ways...
What I would suggest is that there is not a Pareto-optimal solution here short of redesigning how schooling works entirely...
(Our no-longer-elementary-schooler, by the way, never really had this problem. He just seems to sleep a lot less in general.... kids are different.)
Some of the kids mindfulness podcasts (Peace Out as an example) are also good for this kind of thing
The one of reading age is already reading after he's in bed. The hard part is getting him to stop and actually go to sleep.
I will look into the podcasts; thank you for the suggestion!
However, she still seems wired to fall sleep at a certain time, and we finally decided that fighting biology is a losing battle. The strategy of moving bedtime a little bit earlier each day didn't work at all.
One can try but you will be limited by biology: The problem is that our internal clocks are reset by daylight. You can't just shift yourself to another timezone, since your circadian rhythm will always set itself back to the respective local time. So if your brain prefers you to go to sleep and to wake up at certain points it will always be relative to "local (sunlight) time", not relative to human clock time.
I work in the education industry, and the education experts in our company have been saying this for years.
Keep in mind that in our school district, elementary school students need to be in by 8:40 while high school students need to be in by 7:50.
Our neighborhood is setup for walking. The elementary school is a six block walk, so most people walk their kids to school. My daughter didn't sleep past 7:00 for most of elementary school. Our experience was that elementary really could have started closer to 8:00.
I'm with you on all your other points. But, I think our experience was significantly different for elementary school.
