Exactly. If a child was locked in a closet every moment they weren’t at school, but a teacher has them 8 hours a day. They should be able to well educate that child.
Most homework today is the teachers showing they are “doing something”.
Its also the government controlling your home life all evening.
1. Casual reading (anything, really -- except what was assigned to me at school)
2. Working an after-school job
3. Watching contractors at work on construction sites near where I lived, and during the summers when the family was on vacation
In my younger days I taught math in high school. There is no way for a student to learn, to master the concepts without doing homework to practice and internalize the material that will help them in their life ahead - not just knowing the math but using the discipline learned in other phases of life as well. Ditto - history, English composition and literature, civics, etc..
And you don’t have the kid 8 hours a day. Most teachers have them for an hour a day, some for three. If you want educated people you must work at it - demand it.
Many teachers just give out useless homework to show parents that their kids did nothing , only to find that those teachers during the day did nothing and passed their job into parents.
