If you find this essay compelling, you might be interested in the game I'm working on, Codemancer ( http://codemancergame.com/ ). A game that teaches programming, with a compelling story about a girl on a journey to rescue her Father. Coming this Fall to Mac, PC and Tablets.

I tried to hew closely to the principles of Constructionism which were pioneered by Papert, and to make the game accessible to kids who wouldn't normally be interested in programming.

Love the look. And female protagonist is a huge plus - I've two daughters and it amazes me just how much they really want female characters. As a boy I didn't care but perhaps I was unusual.

My first question is how will this teach the use of variables and conditional logic? My daughter has been playing around with programming using Scratch and things like that. But she is stuck with just linear "programs", basically just creating animated stories.

There's other games that seem to have the same mechanics as yours: get the robot from A to B by entering sequential instructions. How do you differentiate? (I mean this as a positive question not a bad criticism.)

I've tried sitting down with her and doing some basics of functions, but it doesn't seem to go over well (she's 10). She _did_ love DragonBox, the algebra-instruction game. Even at 6 she was able to "solve for x" for simple equations. So I think it's possible to sneak stuff in, somehow.

Yes, I find that to be the case more often than not: boys don't care about the gender of their avatar. Girls do.

Codemancer has variables and conditionals, and uses them for various things. Some of the game is very tactical, so conditionals are used to deal with enemies who have semi-random behaviour. There are also levels that take place "in the dark" (with a limited field of view).

Yes, "code your way to the target" games have become somewhat of a genre. I think the story is one source of differentiation, as is the programming interface -- Codemancer has no numbers greater than 5 (arithmetic is mod 6), to keep the game from getting math-heavy. All the functions are symbolic, so there's no reading required.

In Codemancer user-defined functions are "pages" in your spell book. Players can call other pages, and even the page they're on (this is much later in the game). You can also Cast a page onto an enemy who has been weakened. We've seen that kids are pretty comfortable with the idiom of "Pages."

Hey man! Yes, the pages are a really good idea. Among other things, it seems like a great way of sowing the seeds of structured programming.

Can't wait for the game to be released!

Interesting. Do 'pages' support being called with arguments? That was the place I found things like LightBot to be lacking.

[bobbylox]

Yes, in a roundabout way -- feeding arguments sets the variables on that page.

[MichaelGG]

Excellent, thank you! Looking forward to it.

Can I recommend SonicPi. Many of the kids in my local Coderdojo pick this up after Scratch

[cpher]

Wow, this looks great! My older 9 and 8 year-old girls will love this. I agree with the comments below about variables and conditional logic, which might be tough for kids in the 3-4th grade range. Anyway, good luck. Looking forward to the release.
