That's not using tech that you're describing here. You're talking about literally learning some basic computer skills (such as word processor, excel, reading email, some basic website building, use printer, and some amount of programming)

For those, obviously you need a computer and completely agree that those are important skills to learn... But you maybe need to spend 1h/week during last 2 years of middle school on those at the computer lab (as it's been done since the 90s in many schools around the world)

But for any other course such as Math, English (or whichever primary language in your country), second languages, history, etc. : that's where using tech is a mistake

A bit of tech is ok, but it cannot be "everyone does their homework and read lesson on a iPad/Chromebook"

I am pretty skeptical about the value of learning to build websites. I think it is too tempting for students to devote significant time to something that is not foundational knowledge and where they won't get any valuable feedback anyway.

It makes me think back to my writing assignments in grades 6-12. I spent considerable time making sure the word processor had the exact perfect font, spacing, and formatting with cool headers, footers, and the footnotes, etc. Yet, I wouldn't even bother to proofread the final text before handing it in. What a terrible waste of a captive audience that could have helped me refine my arguments and writing style, rather than waste their time on things like careless grammatical errors.

Anyway, I do agree with the idea of incorporating Excel, and even RStudio for math and science as tools, especially if they displace Ed-tech software that adds unnecessary abstractions, or attempts to replace interaction with knowledgeable teachers. One other exception might be Anki or similar, since they might move rote memorization out of the classroom, so that more time can be spent on critical thinking.

Building websites, I agree has little value, but using it as a way to explain basics of how the web works I think is pretty valuable. Web likely isn't going anywhere for a long time, having some basic knowledge of how it works I think very useful for a lot of people. I hate the idea of any more MS apps like Excel being regularly incorporated, but basic usage of something similar definitely can help know of how to use a useful tool/computer skill. Even in the early 90's we had computer labs for learning computer skills which I think there is value. But forcing tech everywhere into teaching is an issue IMO.
The beautiful thing about programming (which also makes edtech such an appealing dream to chase) is that you get immediate feedback from the computer and don't have to wait for someone whose attention is at least semi-scarce to mark your paper.
re: Anki. It is not as optimized but you can do SRS with physical flash-cards.

* Have something like 5 bins, numbered 1-5.

* Every day you add your new cards to bin nr. 1 shuffle and review. Correct cards go to bin nr. 2, incorrect cards stay in bin nr. 1.

* Every other day do the same with bin nr. 1 and 2, every forth with bin nr. 1, 2 and 3 etc. except incorrect cards go in the bin below. More complex scheduling algorithms exist.

* In a classroom setting the teacher can print out the flashcards and hand out review schedule for the week (e.g. Monday: add these 10 new cards and review 1; Tuesday: 10 new cards and review box 1 and 2; Wednesday: No new cards and and review box 1 and 3; etc.)

* If you want to be super fancy, the flash card publisher can add audio-chips to the flash-cards (or each box-set plus QR code on the card).

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.

> Would it be a mistake to use Desmos in a math classroom, or 3Blue1Brown style animations, to build up visual intuition?

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.

> Should we not teach basic numerical and statistical methods in Python?

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.

I would think that it would make sense to introduce Python in the same way that calculators, and later graphing calculators are introduced, and I believe (just based on hearing random anecdotes) that this is already the case in many places.

I'm a big proponent of the gradual introduction of abstraction, which my early education failed at, and something Factorio and some later schooling did get right, although the intent was rarely communicated effectively.

First, learn what and why a thing exists at a sufficiently primitive level of interaction, then once students have it locked in, introduce a new layer of complexity by making the former primitive steps faster and easier to work with, using tools. It's important that each step serves a useful purpose though. For example, I don't think there's much of a case for writing actual code by hand and grading students on missing a semicolon, but there's probably a case for working out logic and pseudocode by hand.

I don't think there's a case for hand-drawing intricate diagrams and graphs, because it builds a skill and level of intimacy with the drawing aspect that's just silly, and tests someone's drawing capability rather than their understanding of the subject, but I suppose everyone has they're own opinion on that.

That last one kind of crippled me in various classes. I already new better tools and methods existed for doing weather pattern diagrams or topographical maps, but it was so immensely tedious and time-consuming that it totally derailed me to the point where I'd fail Uni labs despite it not being very difficult content, only because the prof wanted to teach it like the 50s.

Fwiw calculators were banned in my school. Only started to use one in university - and there it also didnt really help with anything as the math is already more complex
I was allowed to use calculators when I started algebra in seventh grade.

I found that calculators didn't help all that much once you got into symbolic stuff. They were useful for the final reductions, obviously, but for algebra the lion's share of the work is symbolic and at least the relatively cheap two-line TI calculator I was using couldn't do anything symbolic.

I know that there are calculators that can do Computer Algebra System stuff, and those probably should be held off on until at least calculus.

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."

There's an in-between point my math teacher loved using: an overhead projector. Hand-drawn transparencies that could be made beforehand or on the fly, protected large so everyone could see, without hiding the teacher behind a computer - they'd still stand at the front of the class facing the students.
Sure, that would work too. I wouldn't say that's in-between but a technique that can be used without incorporating any modern technology at all.
This has been replaced by a webcam on a stick and a computer monitor.
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.

> 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.

I think the latter is mostly a reaction to the former. I think there is a way to use technology appropriately in theory in many cases, but the administrators making these choices are largely technically illiterate and it's too tempting for the teachers implementing them to just hand control over to the students (and give themselves a break from actually teaching).

>Would it be a mistake to use Desmos in a math classroom

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.

Skills are less important than foundation.

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

> (as it's been done since the 90s in many schools around the world)

I had computer lab in a catholic grade school in the mid-late 80's. Apple II's and the class was once a week and a mix of typing, logo turtle, and of course, The Oregon Trail.

what's funny is that they don't even teach basic tech literacy but just rely on kids to figure it out!
