Seriously.
I'm wondering what sort of qualifications these people have to be teaching children (besides being able to bear them). Are they going to be learning Chem as they would in a 'box' high school? No, in game alchemy doesn't count just as feeding your hunter pet is not the same as caring for real animals. Sure I can see some educational benefits from playing WoW ('I know what GTFO stands for! Iz getz an A'!) but, to use their Brazil example, I don't think it can supplant a course about Brazilian culture or the Portuguese language. I hate to seem like an overcritical bastard, but I really don't think this is the best way to educate children particularly when you consider the lack of importance that our culture puts on intelligence. I don't think kids know whats best for themselves innately and will make decisions that they find pleasurable or enjoyable over those that are necessary to their future prosperity. I think this is evident when children choose to play video games for todays lesson as opposed to creative mathematics, painting or reading a book.
However, I don't believe that the 'box' education is any better. I agree that a child's education needs more real life examples and lessons than are provided in a traditional ciriculum. But one thing a 'box' education does provide is a certain amount of cultural context for the children and it's provided when they're in a group of similar aged peers. And thats not something WoW or solitary home schooling can provide.
And I have to admit: The large majority of home schoolers I've known have had some noticabe level of social akwardness.
My dream: 'Oh hai, teacherz. I dint writez my french paperz but I chated with a guy form Quebec last nite on WoW for like 6 hours. ok?'
'Ok, here your deegree! Winner!"

Kids in school generally do whatever they want, too. Teachers don't care; at least these parents care. When you tell someone not to do something, that automatically makes them want to do it. I figure the kids will get bored with WoW soon enough.

Clearly your higher level of education has done nothing for your basic understanding or acceptance of thinking outside the box. Alchemy is not the same as chem. Congrats on that brilliant observation. It is however representative of it. Mix things together to get something else. The idea behind this kind of learning environment is that everyday interactions and experiences can be expanded to a profound level. A kid in game sees how alchemists make potions. That then leads them to ask how does that work? So they research it. They find out on their own, because they are interested. Just because you were too stupid or lazy to discover things on your own or develop passions for learning, don't assume that others are the same. People that take their own initiative to understand something out of a sincere desire, will without a doubt come to understand it much better and more fully than those that are force fed the same information. Maybe you should learn to actaully think before you flaunt your fears of something different.
