How To Encourage a Young Teen To Learn Programming? 1095
Anonymous Hacker writes "I'm in a bit of a bind. My young teenage son is starting to get curious about computers, and in particular, programming. Now, I'm a long time kernel hacker (Linux, BSD and UNIX). I have no trouble handling some of the more obscure things in the
kernel. But teaching is not something that I'm good at, by any means. Heck, I can't even write useful documentation for non-techies. So my question is: what's the best way to encourage his curiosity and enable him to learn? Now, I know there are folks out there with far better experience in this area than myself. I'd really appreciate any wisdom you can offer. I'd also be especially interested in what younger people think, in particular those who are currently in college or high school. I've shown my son some of the basics of the shell, the filesystem, and even how to do a 'Hello World' program in C. Yet, I have to wonder if this is the really the right approach. This was great when I was first learning things. And it still is for kernel hacking, and other things. But I'm concerned whether this will bore him, now that there's so much more available and much of this world is oriented towards point-n-click. What's the best way to for a young teen to get started in exploring this wonderful world of computers and learning how to program? In a *NIX environment, preferably."
Whether or not you have suggestions for generating interest or teaching methods, there was probably something that first piqued your curiosity. It seems like a lot of people get into programming by just wondering how something works or what they can make it do. So, what caught your eye?
No, it is still correct. (Score:2, Insightful)
Your approach is still correct. The point and click gives results fast, but doesn't actually teach you anything. If he find the basics, boring, don't even bother anymore. Programming isn't for him.
Heck, I can say that programming for me became boring the day I started doing it professionally. I would rather direct my son in a completely orthogonal direction.

Write a game, perhaps based on a favourite book. Or something that involves a subject he's already interested. Doesn't matter if it's a simple text game. Let him write it on his own. Then when he's finished suggest a few improvements. Repeat. Once he's bored with that, start a new project.
That's how I learnt.

Perhaps, but there are many elements to programming some of which are perhaps easier to learn than others. Teaching his son to program may benefit from being able to distinguish these elements. My initial suggestion would be to give him Python because this will let him learn the critical elements of program structure and algorithms without getting bogged down in learning the idiosyncracies of a language like C++ (which I do love). For similar reasons, Python will also offer fast return on investment. He'll be churning out programs that do what he wants them to in half the time he would be in C++ or Java.
Of course the most important thing is probably to let him drive the learning for the most part. If he's a bright and technically minded lad, he may appreciate the power and intricacies of C++. He'll need the language sooner or later if he gets involved in many of the big open source projects which would also be a great way to get involved. Things are usually more fun when done as part of a group.

If he gets the hang of it, you could even teach him how to write a raytracer. That would also be good for his math, and be a nice project where more advanced programming techniques (e.g. data structures, recursion) and more advanced math (calculus, 3D geometry) have practical uses.

First off, I think you should start with a language such as Python or Ruby. I started with BASIC which was easy to grasp, and more modern languages are easy yet more powerful.
Second, when I started programming I was first looking at my brother, writing really simple BASIC programs on the C64. Later, I was interested in fractals and wrote algorithms for drawing fractals. I had a book with code examples for different fractals, but in some other language (I don't remember which). The process of interpreting the algorithm in the first language and translating it to BASIC was very good for learning. Tweaking and extending the algorithms and seeing the changes visually was very encouraging.
Today, if I were to teach a kid programming, I think I would look into Lego Mindstorms [lego.com]. It helps if the kid is into Lego or robotics, of course. That's a contained environment with a powerful and easy language, which is also part of something else, with immediate feedback on the changes. You can program it in either the Lego-supplied RCX Code (BASIC-like) or ROBOLAB (LabView-based), or any of a number of languages supplied by the community (C, C++, C#, Java, Lua etc).

The problem is that you can't foster curiosity, which is the main driver here. Nothing will make you sit down and learn a programming language more than curiosity for what you can make the computer do, whether you can do something better than Microsoft, etc. You can try very hard to keep interest, though, and there practical results tend to have greater effect - this is why most basic ICT in schools is based around roaming turtles, Lego RCX, "traffic-light" kits etc. Computer-controlled with visible, physical effect.
Personally, I think the best way to foster the right computer skills isn't to use a computer much at all (this is a philosophy I've held for most of my life - the best way to program is in your head, not a machine - the best way to write a story is on paper, not a word-processor, etc.). The best things to use to learn are simple gadgets. I'm not a gadget person. I'm not even very good at electronics but I struggle along and get a lot done.
Wire your house for a burglar alarm, controlled by a computer, and involve your children in every step. If your practical skills aren't up to scratch (good, you can "learn" by your mistakes together and your child can try to "out-think" you when you both hit the same problem), you can get X10/DMX-style equipment that makes it a cinch. But there's nothing like a bug that'll scare the crap out of you when the alarm goes off because you didn't cater for a niche-case (opening the back-door while the power was out etc.). It only needs an ancient "sacrifical" computer that doesn't matter if you blow its parallel port, and it introduces every single reason behind having computers - automate tasks that a human could do using simple, cheap components.
You can learn programming, you can learn embedded programming, you learn about the importance of bug-checking and clean code, you learn about interfacing, buses, serial/parallel data transfer, physical and real-world effects and how to counter them in software (e.g. switch debouncing). You even get to learn how the damn computer does its job so that it's no longer a magic box that does stuff. You get to interface with all types of cool gear. You get to bring practical, real-life skills into the learning environment which can help immensely if your child learns better that way. (And I don't count "how to write a letter in Office", I mean REAL life skills, like practical problems, electricity and electronics, wiring, why the bloody ladder won't stay still and why Daddy put his foot through the roof).

The "reward" of having the whole family laugh at a a doorbell that plays a WAV when someone presses it is very rewarding especially when "it was all my son's work". My particular favourite is a doorbell that goes "knock knock" when you ring it. I also bought an old-fashioned door knocker which has an integrated switch in it and want it to set off a "ding-dong" sound, just to see the postman's face. I'm doing it with simple electronics and one of those recorable greetings-card chips but you can do it with a PC easily. Ten minutes of very basic wiring to an old-fashioned joystick port (ancient laptops are great for this sort of thing), a WAV file off a free website and a twenty line program.

I could throw together a game as good as Psion and the gang made for the ZX 81 and later ZX Spectrum, and show it to my classmates and get some serious appreciation. The first game I wrote, when I invited a couple of classmates to see it, they ended up playing it all afternoon. Mind you, it was uber-simplistic by today's standards, but it was as good as anyone could possibly do on a 1K ZX-81.
It was motivating enough to get me started on assembly and converting it by hand to hex.
Nowadays I wouldn't advise anyone to write a game from scratch at home, but there's a _lot_ you can achieve as a mod. And mod-friendly games are getting rather common these days. I can think of a few where most of the game logic (i.e., minus the graphics and such) was Python, one even TCL, and one was scripted in Java.

Show him a prototyping language. Something he can dev in quickly before diving into the deep and mucky bowels of pointers, references, mixed languages, and memory management. These things are not obvious to a novice programmer, and program flow is far more important to pick up early on than that.
I KNOW I'm going to get flack for this, but many people I know who are excellent programmers cut their teeth on QBasic. This language was simple enough to pick up that you could really get coding some complex stuff in under an hour. I would recommend text parsing stuff as a first thing. "Can you pull the hours out of the time?" or "Can you print in words what the date is from the seconds since...". This can be extended to stuff like "calculate Fibonacci numbers" and then teaching how to clean that code up. This is a good time to teach stuff like "code first, optimize second" and how to time code for optimization.
It's also a good time to get him into commenting the code. The way I usually get newbies started on that is to have them write pseudo code or explanatory text before coding, using the comments as a guideline to keep them on task.
If I were to suggest an order of action, try variables & output, input, conditionals, loops, complex conditionals (switch/select statements), objects, collections (sorting searching and maybe memory management here). It's hard to do GUI stuff off the bat because for c/c++ there are so many different flavors available that you can't say "This is how this is done" and be done with it. What might be a good approach is to have him build a game. Start with a MUX and evolve it to a side scrolling platformer, and then to one with 3D graphics (can still be side scrolling, but this way it at least gets flashy).
It's really important to show how to make a responsive program early on. It's a lot more interesting to work with something that can give you feedback in some way. Even a lexical parser could be fun. Find the verb in the input sentence.
When you've done all that, try implementing low level c/c++ code like the String class or Vector class.

So I think writing web apps is not a bad place to start. The main problem is that web apps aren't video games, and all teenagers want to write video games. If our kernel hacker isn't too hung up on Freedom, I'd strongly recommend getting an Xbox360 and setting him up with the XNA framework.

There is also a full, free 3D engine available (TorqueX) which can help him get started with writing simple 3D games without needing to master trigonometry and Direct3D. Back when I was doing this stuff, you had raw OpenGL or Crystal Space if you used C++ and were feeling brave.

It's really easy to do graphics in without having to setup windows and rendering contexts or getting to know huge APIs. It will introduce him to object oriented programming, but won't involve pointers or memory management or any of the more esoteric aspects of something like C++. Another thing is he can easily share whatever he produces with most anyone else who has a browser. If he is at all into social networking online (all that myspace bullshit) he can make some pretty interesting stuff for his friends' pages. Using Actionscript could also lead him to branching out into other web technologies, something probably more important in today's world than ever. It also has a similar syntax to Java or C++ if he wants to go in that direction. And as far as help and tutorials, there's really one of the richest communities around Flash, being a technology that was practically born in the middle of the blogging phenomenon.
The best thing about Actionscript is how quickly you can put something visual together and how little setup it requires. Graphics is definitely the way to go, and nothing in programming has a more immediate "wow" factor than throwing something pretty up on the screen.

driving a truck, or waiting on tables, or shuffling paper, or laying bricks [...] they're not exactly riveting
Laying bricks is close (both construction), but nothing is as riveting as... riveting.

I've had many conversations with various peers around the question, "What do you think is a good first-language?"
When I was first exploring computers, I was using Basic, Pascal and Logo. I don't remember Pascal, and I can't forget Basic or Logo. My first big passion-driven project was developing a Choose-Your-Own-Adventure engine in Basic. It got me into abstraction, simple databases, and eventually graphics.
I think JavaScript is a GREAT learning tool. You can simulate writing to files using text areas or new windows and Firebug is an excellent debugging tool. The language is very approachable and forgiving. Maybe using a strongly-typed language as a first language encourages disciplines that are missing in new programmers, but inference-typed languages offer tremendous power and can lower frustration levels.

There's a lot of very good advice here, but the most important of all is to listen to your son closely to see what interests him. For me, prodding away, I had a fascination with memory storage. Arrays in particular stunned me with their beauty and the first programs that I really applied myself to writing were strategy games that were at heart nothing more than 2D arrays that stored types of units, resources etc. Of course the units themselves were arrays. I might have been an odd child, but the thought of all those numbers lined up and structured absolutely thrilled me. Who knows what will really grab your son's attention? Well, actually, only your son does, which is why he most of all, is the one you should listen to.
You don't have to be a great teacher when the pupil is interested. Just try to learn to answer questions at the right sort of level of detail. That's 90% of it when you think about it, it really is.

By all means, what the previous poster said. Spending time with your son is the most valuable gift you can give him, regardless of the language you think he should learn. Pick a language, buy a For Dummies book, and spend quality time with your progeny. Even if he decides that he hates programming after a year, he will still take away the time spent you as well-spent.

Dudes, don't bite my head off. Nobody ever said teenagers couldn't do kernel hacking, they said that shouldn't be how they are introduced to it. And that's totally right!
Here are some aspects of kernel hacking from a beginners perspective (and really this is what it's about - being a beginner, not being a teenager):
Here are some attributes of video game programming:
Nobody is trying to insult you by saying teenagers should start with video game programming instead of kernel programming. Believe me, I'm 24 so it wasn't that long ago I was a teenager. After I finished with that video game I moved on and by 18 I was debugging race conditions in Wine. But doing that video game was some of the best experience I ever had - it let me practice object oriented design, high performance coding, memory management on a large scale, user interface design, OpenGL, and implementing complex algorithms like A* pathfinding.

When I was a wee lad, I came across and read "Peter Norton Programmer's Guide to the IBM-PC". That book hooked me on all things PC.
It detailed the intricate workings of the PC and the "revolutionary" concept of BIOS interrupts.
Years later, when interviewing candidates for programming positions, I would ask them "When you press the letter 'A' on the keyboard, what happens ?". Their answer would usually be along the lines of "An 'A' shows up on the screen". I would then ask "Why?". If they were able to articulate anything better than "because", they would usually get the job.
I'm now an old person, and I know my views of what programmers should and shouldn't be are probably dated, but I think the worst part about his latest crop of programmers is the total disregard for what actually happens at the machine level. This is what contributes to the crappy, inefficient and unintelligible code that we see being produced today.
Imbue in your son the basics about what a computer is and how it does what it does, and you will be doing him a great favor if this is the profession he chooses to pursue.
I am not advocating that every programmer needs to know how to write a BIOS and put it on an EPROM and replace the one they have in their computer, but at least know what the BIOS is and why it is so important in the grand scheme of things. Nowadays, people learn VB.NET and think they are gurus because they can make a form pop up on the screen. I'd like to see them dive into Microsoft DOS technical documentation and make heads or tails out of Microsoft's "List of Lists" to be able to recover data from an accidentally formatted hard drive.
I'm ranting... just my two cents...
