I have to laugh when I read comments like this...
As somebody who works in the technology side of school districts, I can say with absolute certainty that this comment quoted above nailed it 100%.
It's almost as if you think that they don't have a couple of hundred studies on this kind of learning environment. It's almost as if this wasn't being designed by social scientists and experienced educators.
Yet we see something different, and to us (human beings, although apparently even more than usual in Americans), different ALWAYS MEANS DANGEROUS. Evil. Bad. Stupid. And so we judge, and say it could never work, or it could never work here because Americans are just... what, bad people? Or that even trying it makes these people bad.
It's just like the prison situation here in the US. We have decades of good scientific studies that tell us how to prevent offenders from reoffending in roughly 80% of cases. We have excellent information in exactly how to integrate them back into society so they won't end up sleeping under bridges and having to steal or stave to death. Indeed, we know how to prevent a lot of crime that we see. And the funny thing is, if you factor in all the costs to society of our current regime, it's MUCH CHEAPER to do it that way.
And indeed, there are several countries that are using these methods, to great success.
But do we? No. Because we are terrified of change. Because we would rather make up excuses about how American criminals are just worse than any other criminals in the world, and shove them in piles into overcrowded prisons and let them die because of inadequate medical care (and the occasional case of being tortured to death, thank you Sheriff Joe) than imagine for a second a way to make things better. Because better isn't familiar. Because we're scared of better, maybe even more than we're scared of worse. Because if we try something new and find out it was better, we have to admit that we were wrong about what we had before being better.
See also: health care. We HAVE to believe that we have the best health care in the world, because otherwise something DIFFERENT is also BETTER, and we were WRONG, and we can't have that.
Sometimes it's really tiring watching us Americans stab ourselves in the neck over... and over... and over...
