The EdTech Revolution Has Failed

I took about 60 credits - ~8 hours per week each school semester - of Computer Science courses back in the mid 00's at a top state school. Besides the 101 Course, heavy on Java syntax; and Software Architecture where one learns the dark art of Swing, we used pencil, paper, and white boards (even a few chalk boards!) for the rest.

I use concepts like Dijkstra's algorithm and the Turing machine regularly in my job. They are very real to me - more real than any programming language - because I sat for hours taking paper notes off a whiteboard while some OG Computer guru discussed the topic.

If I didn't need tech to learn Computer Science, kids definitely don't need it to learn Algebra.

What if it is possible to spend a lot less time learning that with newer classroom methods (ed tech doesn't have to mean whiteboards and apps, teaching methods are technology too).

We can make a good house without metal fasteners using hand tools and nothing but muscles. But that doesn't mean that a house built using brushless power tools in 1/4 the time isn't also a good house.

More directly: I conceptually understand a lot of algorithms that I read about. For me though, the ones that I learned by coding them and running them are the ones I understand much better. Hand written notes on a lecture do not guarantee complete or correct understanding, and there is no mechanism for checking.

I didn't even own a computer for my first year of computer science (couldn't afford it), and had a 1½-2 hour commute to school. I did everything with paper and pencil, because when I had to actually turn in something, it involved staying in a giant, crowded computer lab and getting home well after dark after having left well before dawn. I still have notebooks filled with C.

That being said, my mother learned how to program when they were still using punchcard decks. My ordeal wasn't special. Don't know if I learned any better than others, but I think the need to not have bugs on the first iteration was more important for me than for other people. I did not just tweak things until it worked.
