Would it be a mistake to use Desmos in a math classroom, or 3Blue1Brown style animations, to build up visual intuition? Should we not teach basic numerical and statistical methods in Python? Should kids be forced to use physical copies of newspapers and journal articles instead of learning how to look things up in a database?

I'm all for going back to analog where it makes sense, but it seems wrongheaded to completely remove things that are relevant skills for most 21st century careers.

I don't think there's anything wrong with showing kids some videos every now and then. I still have fond memories of watching Bill Nye.

No. Those should be done by hand, so kids can develop an intuition for it. The same way we don't allow kids learning multiplication and division to use calculators.

Those are great examples. Not familiar with Desmos, but 3Blue1Brown style animations are great.

The problem is that people seem to want to go to extremes. Either go all out on doing everything in tablets or not use any technology in education at all.

its not just work skills, its also a better understanding that is gained from things such as the maths animations you mentioned.

Skills are less important than foundation.

And Logo or BASIC >> Python in school context IMO.

Until most kids are about 12 - 14 years old, they're learning much more basic concepts than you're describing. I don't think anyone is trying to take intro to computer science out of high schools or preventing an advanced student younger than that from the same.

I would rather a teacher have to draw a concept on a board than have each student watch an animation on their computer. Obviously, the teacher projecting the animation should be fine, but it seems like some educators and parents can't handle that and it turns into a slippery slope back to kids using devices.

So for most classrooms full of students in grades prior to high school, the answer to your list of (presumably rhetorical) questions is "Yes."

Maybe. Back in the day I had classes where we had to learn the rough shape of a number of basic functions, which built intuition that helped. This involved drawing a lot of them by hand. Initially by calculating points and estimating, and later by being given an arbitrary function and graphing it. Using Desmos too early would've prevented building these skills.

Once the skills are built, using it doesn't seem a major negative.

I think of it like a calculator. Don't let kids learning basic arithmetic to use a 4 function calculator, but once you hit algebra, that's find (but graphing calculators still aren't).

Best might be to mix it up, some with and some without, but no calculator is preferable to always calculator.
