Incorrect. At our local school, kids from Primary 1 use Apple products to help them learn to read & count.
I'm not sure where you live, but here in Scotland primary 1 is the first year at school for 5 year olds. They absolutely use (old) iMacs and iPads at that age at our local school.
Sorry, I'm not being clear. Let me try again.
I live in New York, and yes, they introduce kids to computers very very early. The theory is that kids learn better with computers because they like using them. It's the same theory as teaching kids to count by having them count a pile of cookies as they eat it.
They might use computers in school, in other words, but they don't need them. Reading and counting doesn't require computer skills, and introducing your kids to computers at an earlier age offers no advantages in school. In fact, if the kid is plugged in too much, it might be a disadvantage.
My ice-cream analogy is my major argument. Kids learn to use computers at the level that they need in school very very quickly. My 15 month old is perfectly capable of getting past the lock screen of an iPad and opening folders, *even though we have actively tried to prevent her from using the damn thing.*
Computers aren't like kicking a ball, for example. Every kid will learn to kick a ball, but at wildly different levels. Some kids will be basically incompetent at it through high school. Others will learn so well they will be up front for Barcelona by the time they are 19. I can totally see the argument that if you want your kid to be a star forward, you need to have them kicking a ball as soon as they come out of the womb.
It's the same thing with languages. If you want your child to be truly bilingual, you have a window of at most two years to expose them to both languages. After that, there will be a noticeable difference between primary and secondary languages.
But there is no such analogical skill with computers. There's no such thing as a superior mouser, for example. So I just don't buy it when you say, "If you start school at age 5 and you're not comfortable using a computer, you are behind many of your peers in the class and its tough to catch up." I don't think it would be hard to catch up anymore than it would be difficult to start liking ice-cream.
