Interesting! So if you have computers, your kids are 'screening' all the time?
I put an Apple mac at my ex husband's house to video conference my kids when they stay over there. I have a PC in my 8 yr old son's room. In addition, we have a play station, Wii, xbox, 2 further laptops and a top of the range PC, oh and PSP's and DS's. But, guess what my 8 year old son does most of the time, his choice? 1. read (sometimes a book a day). 2. play football. 3. swim (clubs and lessons). 4. just play out. 5. watch TV. 6. handwrites his story, and somewhere on the list he does karate, and then further along, goes on one of the PC's or games machines. He chose to go on the PC for 1 hour total last month. Seriously, you can't assume that having these machines means the child will not do anything else. But if you think they will...
There's software you can install on a PC that will ban websites,and you can uninstall certain programs (like MSN). I think Microsoft Vista allows you to do this too. You don't need to police them. You can set them up in the first place how you want them.
I use a PC to manage my home finances - I just couldn't do what I do without computers.
But back to the point - using them in schools. I do have an issue unless schools overuse them But, don't really think they do. My 8 year old son says he rarely uses a computer at his school. My 6 year old said she uses a computer a tiny amount of time at school.
The earlier someone learns to use something as complicated as a computer, the more it becomes second nature to them, like riding a bike, driving a car, etc.
I also believe that unless its for religious reasons, children should be given the options to decide for themselves whether they will benefit or not from being fluent with computers. A lot of adults hate them, because they learnt how to use them late, they don't really understand them, they use them in a very limited way and so manual methods are better for them anyway, and they assume kids will use them for negative things, and so on. I do think it's a good thing that ICT is on the national curriculum.
Having said all this. If you do want your child to keep away from computers at school, chat to the head, explain your reasons and you might get somewhere. And when it comes to Secondary school, yes it's a core subject, but they can always just not bother and fail it. But when it comes to doing homework for other subjects, they do now ask for presentations, word processed essays, and so on. But you can get your kids to draw posters and neatly handwrite instead, and just get them to hand it in like that no matter what! It would be accepted. If your kids go on to further and higher education though, they would need then to learn to use computers. Also, for almost all jobs, they will need basic computing skills. There will be basic computer training available for people at all ages for some time, but there will come a time when having the skill is assumed, because it's now part of the national curriculum.
