Want To Get Kids Interested In Programming? Teach Them Computer History

Posted by timothy on from the nostalgia-works dept.

An anonymous reader writes "With poor IT teaching putting kids off pursuing a career in the computing it is time to look for a new approach. Taking kids back to the time of computing pioneers like John Von Neumann and the first machines — the likes of the Z3, the Eniac and the Colossus — would both inspire them and help get over the fundamentals about how computers work, argues silicon.com."

      Why?

      Last week I put together a one-hour implementation of Reversi & showed it to my little brother (he's 12). I expected his reaction to be "meh", since the board was represented by a boring 2D array of dots, Xs and Os representing the pieces, and the input was in numerical coordinates, and of course he's used to cinematic 3D games and mouse input.
      To my surprise, he not only had fun playing, he wanted to know how I had done it, what could be improved, pointed out bugs, and keeps nagging me to fix them.

      Still don't know what the best way to start programming would be for him, but motivation is not the hard part.

      EXACTLY! The way to get kids interested in programming is to encourage curiosity -- give them the code to a simple video game (tetris? Space invaders?) and let them tinker with it.
      Nibble & Byte magazines used to list page-after-page of source code for Apple][ games. Typing that in, debugging the inevitable mistakes, etc. are good practice! Or show them the amazing old BeagleBros. 2-liner programs.

      Most kids, especially boys, when given something like a programmable game that they can play will spend hours doing things like changing it so they get a million points, or changing it so their character looks like a penis, or changing it so that there are a million things on screen, etc.

      It's actually *not* a bad way for them to learn at all. See, understand, experiment, see results of experiment, tinker more. It's how I got into programming at first - sure there was a lot of typing in listings, etc. but the coolest bit was to be able to tweak the QBASIC Gorillas game and things like that.

      In my early teenage, I was ripping the graphics resources out of games like Castle of the Winds and trying to create my own version, and cracking the CD protection on Desert Strike for myself so I didn't need to keep swapping the fecking disks (I did that using MSDOS debug and a copy of Ralf Brown's Interrupt List).

      But the greatest initial impetus, that hooked my entire maths class on silly graphical-calculator games I was writing, was for them to see the code, tweak it and start to understand how it worked.

      I spent hours with a teenager who was working under me for his work experience (two weeks in a "real" job while they are still at school) explaining how to program and the most interesting thing was that they couldn't see how, e.g., 3D, sound, joysticks, etc. could be thought of in the same way as the numbers they manipulated in a basic dice game. Once they realised that everything from networking to 3D to AI to physics was just a matter of manipulating numbers, the "magic trick" of their console games was revealed and they wanted to replicate them.

      Last year I wrote a simulator of a VERY simple computer. It had four instructions, 16 bytes of memory, and 2 registers. There were no branch instructions; literally the only thing you could do was write a program to add two (8-bit) numbers together. (And it would set the error bit if the result was bigger than 255.) I gave it an interface of nothing but (simulated) LED lights for the registers and memory, and then (simulated) push buttons to select a memory address and poke a value into it. It looked like a relic from 1956.

      I then explained it to my then 9 and 11 year-old sons (who both are teaching themselves to program), explained base-2 math, explained how the "computer" worked and the four instructions they had available, gave them a whiteboard, and tasked them with writing a program to add two numbers.

      They went NUTS! They were discussing theories, pointing out errors in each other's ideas, and getting excited when they fixed bugs. And they were doing it with a maturity level way beyond their years. They loved it. And I think that part of it was because it was simple enough that they felt in control of it. I also had the memory lights turn green as the instruction pointer advanced, so they could watch the program running. (It was slow enough that they could follow it and watch the registers change.) Granted, my boys love history, so that may have sweetened the deal for them a bit. But I was shocked at how easily they picked it up and how much they enjoyed it.

      I'd like to expand it to the point where they can watch a stack operating, and see pointers and offsets getting used, but I just haven't had the time to follow up on it. But it confirms (for me) that the idea of starting at the beginning might be the most effective way to teach programming. (I also taught programming at a local trade college for a few years, and I noticed how much harder it was for the students to pick up--say--OO programming concepts when they had never had to deal with the problems that OO concepts were designed to solve. Trying to simplify it even more for elementary school students seemed mis-guided.)

      The very best part of the story was six months later touring the Mercury Redstone program blockhouse at Kennedy Space Center (I know it's not technically on the KSC property, save your breath). They had an old Sperry-Rand computer with a console full of lights, and both boys lit up and told the (confused) tour guide "I KNOW THIS! I KNOW HOW TO PROGRAM IT!". It nearly brought a nerdy tear to my eye.

      P.S. If anyone is curious for more information I'd be happy to share. It wasn't very complicated, but I think it has a lot of potential.

    Because there's nothing more that kids love more than history lessons. Seriously, most kids have access to a computer these days. Those with the interest and aptitude will find themselves in the industry or academia, more likely through gaming than through history.

    Given the opportunity to teach Informatics to Diagnostic Radiology Imaging students, almost all in their 20s, I decided to start with a first lesson about history of computing, and I started from the ancient times when the most sophistcated calculator was the abacus.

    The reason kids find it difficult to learn programming is because it is taught in a drab uninteresting manner.

    Well at least there are no false expectations of fun for when (if) they get a job coding ..

    Sorry, this article presumes a falsehood.

    What poor teaching in Comp Sci is going on where exactly?

    The reason people are leaving IT is because the job opportunities aren't there. I'll say it- outsourcing and H1Bs in the US and similar measures in other countries. .

    How long does it for word from the older brother / friend to the younger brother / friend that the career choices aren't there and they should major in something else?

    How rampant is age discrimination in IT?

    When the boom hit in 1990s , people poured into IT because of the job opportunities. If this thesis is to believed , it was because the teaching was somehow better back then and today it's gone downhill, so people are leaving.

    Nice try. It's all about the economics of being a software engineer. The two things that have changed those economics are
    1) oversupply of labor through the devices of outsourcing and false claims made by corporations of desperate IT labor shortages coupled with lobbying Congress to increase, or make unlimited, the number of visas available for IT workers.
    Software patents which stifle innovation and curtail opportunities for programming entrepreneurs.

    The fact that both of these policies give unnatural leverage over marketplace dynamics to large corporations who in turn fund the re-election campaigns of the lawmakers who pass these laws means means ... everything.

    The free market is a great thing until it works to drive up wages for workers. Then it's a tragedy of epic propositions and someone somewhere has to do something!! That someone is generally your senator.

  7. RCA 1802 by Kupfernigk · · Score: 4, Interesting
    In ancient history, if you needed a really low power microprocessor based system, there was a processor made by RCA called the 1802. It was CMOS, and I once demonstrated a development board running off two lemon halves with a copper and a zinc rod in each one. It was very slow but, and here is the point, it could be clocked down to zero. You could single step, not just instructions, but the entire cpu fetch/execute cycle, see the memory address go out on the bus, see the data. Although it had a stack pointer you had to manipulate it programmatically, and write subroutines to handle subroutines, nesting and returns.

    It stuck me then it would be the most perfect teaching tool, because you could do anything with it from teaching the von Neumann architecture to running BASIC on a terminal. The processor and its support chips are long dead (I'm writing about the late 70s), and there doesn't seem to be any modern equivalent.
