Hacker News Stories and Comments

All the comments and stories posted to Hacker News that reference this video.
Interesting, personally I think mobile devices and laptop/desktops have differing roles and both have their place. Funny you should mention switching to a desktop to teach them Python, I'm teaching it to mine using Pythonista on iPads because I do a fair bit of coding for fun with it on the train.

No one device can be the be-all and end-all. Yes my daughters watch a lot of dreck on Youtube, but my youngest recently got really excited and showed me her 'favourite video'[0] and told me about this great channel she'd found called numberphile. My eldest watches tons of Anime, but recently got into AMV (Anime Music Videos) and is working on one for herself using Garageband and iMovie on our desktop. It's not the tool that matters, it's cultivating the mind and attitudes that count.

On devices in formal education, I don't think any good can come from kids carrying around any device to use in classrooms all the time until at least high school age. I'm a big fan of using computers educationally, they have specific places and roles to play in that process and one solution simply doesn't fit all cases. iPads, Chromebooks and 'proper' desktops and laptops all have strengths and weaknesses. I'd no more outfit a school entirely with one or the other than I'd replace everything on the road - lorrys, cars, buses - with one kind of vehicle. Tying kids permanently to one specific device just makes no sense to me.

If this floats your boat then the inimitable Vi Hart has done a series of videos about space filling curves and related matters:
