I'm a year away from teacherhood and just thought I'd throw in something I had noticed.
My internship last semester was in a semi-rural 3rd grade class - the only third grade in the school. I know of several times during my internship (I was only there 8 days during the semester) that the entire class was held in from recess because they hadn't turned in homework. It wasn't an effective discipline method for that class, at all. Neither was writing an essay over whatever they did wrong in class.
My stepson, 6, was held in from recess the other day for hiding homework in his desk. ITA that the large majority of homework is busywork - I'm very honestly looking forward to him homeschooling next year: less junk paper all over my house, more time he has to enjoy being a kid, and LESS fighting to get him to work on his work! Unfortunately, he isn't the kind that gets it done in school and pretends he doesn't know what he's doing at home. He is very smart, but has no clue what he's doing half the time because he doesn't listen in class when it's explained to him and won't take the time to read the very simple directions when he gets home. He just wants to argue for 20 minutes about not knowing what to do (sigh). Then there's the effort for trying to get him to do it right. He seems to think the name of the game is 'How quickly can I get it done?' and then has to keep working on it for the next 15 minutes because it's important to DH and I that he is able to get a correct solution for two single-digit numbers!
I hate, hate, hate worksheets. I especially hate the ones where they are supposed to color it afterwards: surely there's a more meaningful way to get the information across! And for teachers, who really wants to grade all those?
I really like the idea of assigning homework as daily reading and writing projects to be turned in at the end of the week. Thanks for the ideas

What I've been told here is, get through the first 3 years doing it the way the school wants you to and then you can do it your own way. Looking forward to that

I'm also of the belief that children NEED the recess time. It's a bit of stress relief for them. I'm perfectly fine with my stepson being held in, though, because we have had an issue with him not bringing home papers all semester. When he hides the papers in his desk, it feels like the teacher and myself are both being lied to - the teacher is thinking he's taken his work home, and we're thinking he didn't have any work. No busywork is fine with me, but I want to know if he does have it!
