In reply to Heike:
One of our friends home schools her twins who are now 7. This is what she thinks as we have discussed it a few times so not my immediate experiences but hers and I hope you don't mind, but my opinion as well based on her experiences.
She freely admits to struggling with it. She finds it difficult to "teach" them all day. They go out quite a lot to the park and learn stuff that way, museums etc etc but to try and get them to sit down to learn all day in a made up garage classroom Isn't ideal. She has converted her garage into a teaching room and the local schools are excellent. They have provided her with help, resources, curriculum updates etc but regular trips out with me for coffee and chats (during her school teaching time!) indicates she is going to put them into school.
She Isn't consistant enough with the teaching, she and they get distracted and the most difficult part of it is that the kids learn from their peers and as there are only 2 of them in the garage, they are not being exposed to all the other children at school and I think this has made them a wee bit insular. She freely admits all of this and kudos to her for giving it a go but from her experience she says it is bloody difficult and with all the best will in the world, she can't provide them with the correct environment for learning. The other kids at school learn an awful lot through group play and they are learning quickly as part of a group whereas the twins are learning but are a wee bit behind the curve. Also, from my point of view, I would like my daughter to have some competition to a certain degree to accelerate her learning.
Also, when do you stop? I think, as she does now, it is unfair to teach them so much and then send them of to school where they are put into an alien environment with other kids who have all been together for a while, all know each other and all think the same way to a certain extent.
Also, just because you found school boring and didn't like it, doesn't mean your child will be the same. I hated school but the way we have brought our daughter up means that next year she can't wait to go to school to be with her mates and there is so much more she can learn there. Piano, gymnastics, sports, after school classes etc etc. The only thing I am going to teach her is german and a wee bit of french and of course outdoor pastimes which we already do (windsurfing, kayaking, climbing, skiing).
Without soundng derogatory and hopefully my post has been balanced, I wouldn't do it. I have a lot of skills but I don't have the necessary skills and know how to teach our daughter in the way that she is supposed to be taught in the early years. I think my job as a parent is to help her learn and teach her the other stuff, manners, respect etc and let the teachers teach her the stuff she needs to know and then let me reinforce that at home and encourage her.
Viel Glück!
