"My children do not sit at home studying alone with me. They play together; spend whole days at friends' houses or with friends here; read; watch tv; play some more; visit museums with their family or with HE groups or with one or two other families; read some more; do baking, sewing, knitting, sticking, making; play in the garden; ride their bikes."
NotAnotherBrick: my children do all that (apart from visit HE groups that is) AND go to school. For me, school ADDS to the above experiences, which are free-time activities to me. When as an adult an you honestly spend all day doing free-time kind of stuff, unless you become a SAHM or are unemployed? It's a fact of life that as an adult most of us have to go out to work and do a paid job - parts of which we might find boring, repetitive, restrictive, or whatever. For me, school is something which helps prepare children for this aspect of adult life.
Someone further up mentioned that at the Home Ed group meetings "the children are in control." Sorry, can't remember who it was, but whoever it was - can you tell me what you mean by that? Do you mean that the children choose their own activity or what they learn next etc? Because to me, that's all well and good, but again, how is being in control teaching them how to just get on and deal with the boring bits of a paid job? Or having their line manager giving them a task and expecting them to get on with it without moaning and whingeing that they aren't in the mood for it?
OP, don't get me wrong, I am not completely anti home ed. I would do it in a heartbeat if my child were getting bullied and the school didn't resolve it. (and if we could afford for me to give up work!)
It's just that, as other people have pointed out, it sounds as if it's more YOU that has the issue over formal schooling rather than your child.
Re: the issue of homework - that does seem an excessive amount and if it's causing your child to be so tired and drained then could you not have a word with the teacher and come to a compromise about the amount that your child is given?
