Ask Slashdot: Best Strategies For Teaching Kids CS Skills With Basic?
beaverdownunder writes We're currently working on developing a teaching platform based around our BASIC interpreter DiscoRunner, and we would love to hear from Slashdot readers as to what methods they've used in the past to teach kids computer science concepts — which worked, what didn't, and why? This will obviously be invaluable to us when it comes to working out the lessons that will be taught in our fight-to-save-the-world-from-evil learning environment, and we would be eternally grateful for any scraps of wisdom you could toss our way.
That, and give them a problem to solve. Better yet, let them find a problem to solve.
So much this. Programming is a practical skill, not unlike juggling. There's ultimately very little beginners need to learn, the bulk is merely practice and experience.
Good beginner problems, unfortunately, are really difficult to find. My go-to problems are "math quiz", "triangle", "pyramid and diamond", "NIM two-players" and "NIM one-player". "Math quiz" and "NIM" are self explanatory. "triangle" and "pyramid and diamond" need a bit of explanation. Essentially the student is challenged to accept a height as input and output a right-triangle (made of asterisks) to the console. The pyramid is a more advanced variation of that, where they output a pyramid instead of a triangle. As a second part of the pyramid puzzle, they're tasked with outputting a diamond (essentially two pyramids with one inverted, forming a diamond.)
Required reading for internet skeptics
1. Drop the Applesoft BASIC clone.
2. Create a programming language that natively interfaces with Facebook API, Minecraft API or whatever other software project they actually care about.
3. Show them a "Hello world" example.
4. Wait five minutes.
5. Classroom full of programmers.

It's Melody Ayres-Griffiths.
I wasn't sure if it was Melody, or her partner April. I know 'of' them (I have a voluntary position on a community funding body, so I've seen previous "software" by them) - so I chose my words carefully when describing the "market", the nature of some (many?) of those trying to, um, mine it - and what I'd want to see before I'd vote in favour of funding it. Melody(?) has previously promoted this latest 'project' on /. celebrating 1000 downloads (by who?).
Whois showed the current registration was recent , hence my comment about, um, young code.
DiscoRunner is different because:-
Yes, I'm a jaded cynic (and Australian).
You haven't identified the problem you're trying to solve. At least you made a huge mistake of asking here since you're asking for opinions from an extremely opinionated community without taking the time to actually identify what it is that you're actually having problems with. It seems you just haven't even bothered thinking about it.
1) Are you trying to teach CS to children? Is this the goal? Have you considered asking whether people with legitimate pedagogical sciences experience and studies have identified methods of teaching children topics of this type?
2) Are you asking if there are other tested methods of teaching children computer science which have proven effective that can be adapted to the tool you want to use?
3) Are you in love with a certain tool and while it has almost no practical value to anyone else, you considered it might be a great way to teach kids and now you want to see how you can justify the existence of such a tool (which should simple be, it was fun to make) by trying to use it in CS education of children because "Hey back in the 80's I used AppleSoft Basic and learned from that!"
4) Have you stopped for a minute to decide whether you're narrowing your scope so much by choosing a specific tool and language that your first goal should have been "How do I teach kids CS?" and then "Are there any learning platforms already available for this?" and then "What are the benefits of making a new learning platform using a language like BASIC when the rest of the world, using well funded pedagogical studies have chosen alternative approaches?"
5) Why are you trying to choose a language as a tool. You want to teach principles and things like linked lists and design patterns just are damn near impossible to implement in your language. Any form of real math is also shit in BASIC. Yes, we managed to do these things back when a PASCAL compiler cost $400 and a cheese burger cost $2 and BASIC was free. We have moved on.
6) What are you actually hoping to teach with BASIC? Are you trying to teach them how to draw a line on a screen? Are you trying to teach them to do math? Teach them to do something more applied? What kind of tasks do you actually plan on teaching them? Did you honestly put any thought into this at all.
I know I'm tearing you up here, but I hope you'll consider it tough love. You're trying to mess with children's minds. This is more than just a fun toy... you need to consider the implications of things like "If I teach them BASIC today, will it actually assist in building interest in kids that otherwise would have never programmed or will it chase off the kids who thought it might be fun but were scared to try and now will never try again because it was too nerdy."
There are people who spend decades researching how to introduce topics like this into schools. They don't just say "Hey wouldn't it be great if we made them play with this for a bit!". These people instead are educated not only as engineers but as school teachers. Most of them have at least one masters and one bachelors and they think in terms of "How can we most productively introduce a topic like programming and CS to children" and then they research it with teachers, parents and children.
I think you are very cool for being interested in getting involved.... I hope I gave you some food for thought and I really hope you take your ambitions further and accomplish your goals... once you figure out what they are.
