Splash - Teaching kids to program with what they already know
|
||||
----------------------------------------------------------------------------------
|
||||
About a year or two ago, I set out to teach one of my younger brothers the basics
|
||||
of programming. I found myself somewhat astounded at a few things, though:
|
||||
|
||||
1) The kid was so beaten down by the public school system that he expected everything
|
||||
to be explained and done for him
|
||||
|
||||
2) He had no interest in trying something out until it was 100% shown to him.
|
||||
|
||||
Some people might think this is fine, but I find it horrifying. Kids should be able
|
||||
to try out programming with a clear mind. See, while programming can be a lot of
|
||||
mathematics and hard logic, it's also an exercise in free thinking. Answers don't
|
||||
(at least, rarely do they ever) just come to you in this field, you're required to
|
||||
think.
|
||||
|
||||
I looked at a few of the available options/languages aimed at kids: there's
|
||||
Scratch (http://scratch.mit.edu/), a really graphical (almost lego-ish) approach to
|
||||
programming. The idea is to get kids thinking about logic without worrying about
|
||||
programming, but I've witnessed first hand that this approach doesn't work. For some
|
||||
reason, kids don't get things like branching logic up front, and Scratch does nothing
|
||||
to explain the core concepts, it just dumps kids into a playground. Alice (http://www.alice.org/)
|
||||
is very much in the same boat (if not worse).
|
||||
|
||||
Shoes (http://shoes.heroku.com/) was a novel approach that had potential, but then someone
|
||||
decided to throw a fit and give up on a great concept. Go figure.
|
||||
|
||||
How is Splash different?
|
||||
------------------------------------------------------------------------------------
|
||||
One avenue where kids can still get creative and let their brains flow is creative writing.
|
||||
The act of coding can be very much likened to that of writing a story. When a child writes
|
||||
a story, they're programming without realizing it. The logic and thought that goes into a simple
|
||||
tale can easily make up an entire program.
|
||||
|
||||
Splash is an attempt to capitalize on that capability. Splash programs are literally a story -
|
||||
the trick is that, like any grade school vocabulary exercise, you "define" the terms and words in
|
||||
your story. Check out this example:
|
||||
|
||||
noun daniel:
|
||||
color: #307ace
|
||||
picture: box
|
||||
position: 50 50
|
||||
end
|
||||
|
||||
noun store:
|
||||
position: 100 100
|
||||
end
|
||||
|
||||
verb ran:
|
||||
who: daniel
|
||||
position: store
|
||||
end
|
||||
|
||||
daniel ran to the store.
|
||||
|
||||
The final sentence is the program itself. Before that, we've just defined the terms used. It's pretty cool - verbs
|
||||
all relate to an object, etc (e.g, who ran? Daniel ran).
|
||||
|
||||
This is all very early stage, mind you. I've written a basic parser that translates things down...
|
||||
|
||||
Wait, where does this run?
|
||||
----------------------------------------------------------------------------------------------------------
|
||||
Oh yeah, that's the best part.
|
||||
|
||||
Splash programs "compile" down to Javascript, and can (will) run in any browser. The core of Splash will always be free
|
||||
and open source - kids shouldn't be denied access to a great learning experience.
|
||||
|
||||
There's nothing else out there where a kid can write a program in a format they already know, and be able to run it anywhere
|
||||
(Desktop, Laptop, emerging devices (iPhone/iPad/Android). Rock on.
|
||||
|
||||
Currently, to compile a splash program, you'll need Node.js and a Unix system. For portability purposes, this may be rewritten
|
||||
in the near future, we'll see how it goes.
