There is no question in my mind that children are beginning learning on computers too early. Today's parents, in their never-ending quest to protect their children would rather have their child sitting on the computer in the corner of the living room then running around and playing outside. After all, it doesn't matter if my child is obese because he doesn't exercise, a lot of kids are. And, it doesn't matter if my kid doesn't develop any social relations with other kids, he can talk to people online. Or, my personal favorite, my kid has to get a head start on all the other kids so he can get a better job when he grows up.
What we really need to improve education is a diverse course offering. When I read that art and music programs were cut for a computer program, I got sick to my stomach. In study after study, it has been proven that increased art and music education lead to better scores on math standardized tests. I am quite sure that the ability to use a computer program has very little to do with the development of the brain. As the author said, "we [kids in a classroom] were happy [on computer days] because we had an hour that we didn't have to think..."
It may sound as if I am completely against technology in education. That is not true at all. What I advocate is that schools and teachers use technology the way it was meant to be used - as a tool. What many of the mentioned programs are trying to do is to use it as a curriculum, or even worse, as a substitute teacher. We also need to teach children how to use these tools in a meaningful way. Would you teach a child what a hammer does by telling him to hit his knee with it? Of course not, but this is what we are, in effect, doing when we set a first grader in front of a computer. The child must learn the limits of the physical world before simulating the limits on a computer.
One additional point: the most disconcerting aspect of computer use in an educational setting is the associated demise of the development of interpersonal skills. If a child does not grow up learning to respect adults and peers, what kind of an adult will he be? Surely not one that I would want to be associated with.
