"being engrossed in computing/wii/DS type games is actually going to hold back your child from autonomous learning."
disagree entirely. Having had three autonomously home educated children, one of whom was mad about pc games, there is loads to learn from such games. It is just another way of learning.
And if you really are allowing autonomous education for your children, then this is a valid way of learning.
From Joyfully rejoycing-an unschooling/autonomous HE website
"Here's something Deb Rossing wrote about what kids learn from video games:
Problem solving, reading, research, numeracy (number concepts, 'math'), computer literacy/using the Internet, literature (plotlines, characters, context, setting, mood), music (some videogame music has actually been released on CD because the soundtracks are amazing), team work (many multiplayer games require working together to accomplish a task), patience and sticking to a task to reach a goal, strategy/planning, delayed gratification - if you go straight for that sack of gold that you can see straight ahead, you'll get killed BUT if you go around the other side and wait for the 'guard' to go past, you can grab it safely, art (the graphics and production values of videogames are usually very high quality). Often videogame playing will lead to interests (short or long term) in graphics, art, film production, creative writing (inventing story lines and characters), programming, special effects, music (sometimes DS will hear a new piece of music and say "that would be good for such-and-such type scene in thus-and-such type game"), languages, and other things. Some games either came from or spawned print forms that are related - manga, graphic novels, books, etc.
And, coming back to it, I realized that in the 'delayed gratification' area I forgot budgeting - delaying purchasing some items in the game in order to get something else, planning purchases, figuring income, sometimes actually 'working' for the coin of the realm in order to purchase something - whether working entails beating a gym leader or crafting a potion or creating a t-shirt or buying an item at auction and selling it at a profit, whatever; etc.""
We are totally autonomous home educators-we didn't restrict any screen time, we engaged with them about it, discussed it lots, but didn't restrict it. My child-as with hundreds of other autonomously HE children who played masses of video games, is doing really well at Uni now. So something seems to have worked.
