Human biology likely makes it harder to write on a glass screen with a perceptible Gap in time, latency between where the pen is and where the pixels appear as well as the physical colocation Of the pencil tip and the written line differs more so on a tablet screen than on direct application of matter to paper.

This confuses us, a little tiny teeny tidbit. And that is not helpful!

Plus because glass is slippery you must rely on your visual system nearly entirely for part of the handwriting performance. Because it's not paper you can't measure distances using tension that your nervous system picks up inside your hand, nearly as easily as you can when there's a high friction surface like a piece of paper to rest your hand on.

Also there is visual fatigue of staring into a light, the LED or OLED backlight, which does flicker imperceptibly but it does tend to flicker. This is more of a strain.

Plus there is disorientation... Your tablet can infinitely scroll long past the point at which your body physically dies, whereas if you run out of paper you got to go get some more paper. You write to the end of a sheet and there's no complex thinking involved around virtual viewframes and scrolling and using the scrolling UI.

No matter how you restrict it with MDM profiles, it’s distracting compared to pencil/paper.

The point is that it's foolish to require inserting an iPad into the classroom purely for the sake of using an iPad. The goal (or proposed benefit) should be identified first, and then decide what the best tools to achieve that are.

That's being done, but it would not be sufficient to satisfy the powers that be.

You can just use a pencil and paper, and it's a lot cheaper?

For awhile I tried all sorts of digital notetaking devices. Eventually I realized that pen + paper notebook was vastly superior to all of them for retention, ease of use, and cost. I am sure that, for some people, the calculation is different (for example, I have a pretty good memory and thus writing something down once is sufficient for me to recall it later) but for me, the idea of a digital letter pad eventually seemed utterly wasteful and absurd to me.
