I've talked to teachers who said that they've started seeing young children with picture books doing the zoom in/out pinching motion on pages.
I remember the laugh of a guy in 2008 when I scrolled with my fingers on his blackberry's screen. Now I own a Blackberry KeyOne and it is a reality.
Early versions of iOS were rife with skeuomorphism. Is it sad that iBooks displayed your books on a wooden shelf and played page-turn animations that look like paper, or is it just an application of existing skills and knowledge to a different technology?
Paper books are obsolete. Some people think that they aren't obsolete because they're using tiny low-res monitors or don't know how to use a document manager or haven't used an Apple Pencil, but digital text is just better. I don't care whether young people know what to do with a paper book, but I do care that they know how to interact effectively with text. I'm far more perturbed that schools waste countless person-hours teaching cursive handwriting, but most don't teach typing.
Restoring/downloading a new copy of a partial damaged digital book takes less time than it took me to type up this reply.
I might be biased by growing up with paper, but writing on my iPad with an Apple Pencil makes me feel very different things compared to writing in my notebook. Paper is physical. I can rip paper, I can spread my paper notes on the floor, I can put them away and find them 30 years later etc.
To me comparing writing on paper and writing on an iPad feels like comparing walking to travelling with an electric scooter. Yes, both take you from place A to place B, but they have very different implications and are very different experiences.
Say you give a child a maraca, and s/he learns that s/he can shake the maraca to make noise. Then you hand a child a block, s/he is going to shake the block to see if it makes noise. The interesting bit and teachable moment is that these things have different features and properties and we interact with them differently, and thus we use them for different things. How does a touchscreen fall outside of that?
I say this as a recent parent who is hesitant to introduce screens and approaching the subject carefully.
Also, that video is hilarious, and it's clearly for the best that he's been pulled over.
Children (and adults) learn from their interactions with items, be it technology or not. Attempting to use "touchscreen behaviors" on something that isn't a touch interface is just another learning moment. They're attempting to use their knowledge and experiences to explore the world around them, as each generation did before us.
We're just more connected than we ever were, so this behavior is now more noticeable due to that connectivity and sharing.
