Sorry- I forgot to mention this in any of my other posts on this, but it's probably the most important part of why I do think the school has the right to do this.
Sites like myspace and facebook extend the clique atmosphere outside the school. There's bullying and taunting and isolating, etc. that can now go on totally without any adult supervision- outside of the view of the parents or the teachers - though it impacts the atmosphere in the classroom. The kids come in talking about what's going on in myspace and reenact it in the classroom. So it does impact the school and classroom-often in a negative way.
Another thing you might want to think about is how important it is to know who your kids are talking to. And I don't just mean- know their names and what they look like- I mean know their life situation, etc.
You can't get a real sense of that from my space.
Finally- I personally just don't think sitting in front of a computer screen is productive. I'd rather have her on the phone, going to movies or shopping with her friends, riding horses, whatever. That's just my personal bias-but I don't think it would hurt most kids to spend less time sitting in front of a screen of one type or another- experiencing life passively instead of actively.
When I would have a gripe with a classmate the school would say, take your grievances off the school play ground. I am not advocating for my space, but it is a way grievances can be let out in the open (as opposed to being suppressed) and then possibly dealt with in a reasonable manner. When grievances are handled and talked over kids learn healthy interaction skills and they do not bottle up their emotions to become more of a problem as an adult.
When the world teaches your child some of their lessons in the school of hard knocks then your child cannot blame you for being their nemesis. As long as you are there to help them reason out their difficulties then you become a guide rather than a wall.
Kids are sometimes too isolated from society so they do not learn how to make wise informed decisions.
Emerson said we need to be the same person in isolation that we are in the midst of a crowd (I have paraphrased). This single faced person needs to be socially developed by trial and error. It is best to act out as a kid and learn discipline before you are an adult and hold the lives of others in your responsibility and care.
It is like the idea of jail. When a person becomes dysfunctional in society they lessen their roll in society by isolating them from society. This only separates them from learning the skills in real-time that they need to know to function with proper etiquette and manners.
A child needs to learn how to ride a bike alone, kick their first touch-down. We can't hold their hand on their first date etc...
Yet, I firmly believe it is better to shelter a child than to let them run wild. When they are sheltered, they learn discriminately and this can lead to a healthy sense of self. For the ugliness of the world comes soon enough and then the comfort and peace of childhood vanishes from this life.
