The problem with homework is the total lack of coordination between teachers. They’ll all pile on on one day and wonder why students half-assed everything. Even if they do coordinate, it only takes one teacher overassigning to ruin it for everyone.
Our trig and calc teacher (taught both, had her two years) gave 45-90 minutes of homework every goddamn night, unless we'd had a test.
She was a major part of why I just gave up on doing a whole lot of my homework in high school. That's a lot of time period, let alone for just one class, and others would assign work, too. Screw that, I'd already spent a workday of time in school.
College was such a relief. So much more free time even if I did 100% of what professors asked of me. So's work life as an adult. High school is batshit crazy.
Both trigonometry and calculus are classes that I think should be dropped in high school. I think it would be much better to teach probability and statistics (without calculus) and personal finance. A lot of the math curriculum in high school doesn’t make sense for someone not planning to major in math.
I’m already dreading the arguments with teachers over this when our girls go to secondary school. But I certainly will argue with them over it if coordination is poor and quantity is excessive.
