Squeakfest 2013 in Uruguay

There will be a Squeakfest again in Uruguay at June, 7th - 9th, this time in Atlantida. Etoys will cover the major part of the event, but there will also be workshops in Python, turtle art and robotics. After all, Uruguay is the country with XO-laptops in every elementary school and teachers are using the software which comes with Sugar.


From our education team, Randall Caton and myself are going to present Etoys workshops. This year, I'll introduce Kedama. I'm looking forward to an inspiring event!

If you want to help or know someone who would like to, I created a crowdfunding page to collect money to help to cover our travel cost. Please share as you like!

Ask him: how did the invention of agriculture influence "civilization"?

Or: what is ultimately more powerful, competition or cooperation?

Cheers,

Thank you Bert for the link.

I am not sure to understand this metaphor with agriculture.

"One way to think of all of these organizations is to realize that if
they require a charismatic leader who will shoot people in the knees
when needed, then the corporate organization and process is a failure.
It means no group can come up with a good decision and make it stick
just because it is a good idea. All the companies I’ve worked for have
this deep problem of devolving to something like the hunting and
gathering cultures of 100,000 years ago. If businesses could find a
way to invent “agriculture” we could put the world back together and
all would prosper."

If someone could explain me what it means.

Thanks,
Benoit.

How can I color one character of text?

I am working on a word recognition/typing program in Etoys for Haiti. (and anyone else who needs it).


I need to be able to change the color of the character at cursor.

How can I do this?  (squeak code is fine)

Thanks,
Stephen

Uruguay en NYT Video Juegos


: Uruguay's Video Game Start-Ups Garner Attention
By SIMON ROMERO
The country may be better known for its flocks of sheep and
herds of cattle, but attention is shifting to its growing
start-ups that are engineering video games.

Re: a little help for my master ;)

Bruno,


Excellent question.  I have run into the same problem where a child will draw a complete scene with many objects (for example two fish, some plants and bubbles) to create a fish tank all in one "Etoys object".   Then they want to make the fish move, but the script moves the whole "fish tank." So in this case the "Etoys object" is the drawing of the tank or the tanks "costume" to use the Etoys specific term.  But in the child's mind they are separate objects, that she simply drew all at once.

Let me try and give some definitions from an Etoys perspective (hopefully folks will chime in and make corrections as necessary):
So from an "Etoys perspective" an Object is "Costume" and optionally a set of scripts and variables to manipulate that object.  The "Costume" is the what is displayed on the screen.  So when you "Paint" an Object using the "Paint tool" you are creating the "Costume" of a single "Etoys Object.  

How an Etoys object maps to the mental models inside the child's mind is a good question.  So lets say a child paints a single Costume for an Etoys object that has two fish. To the child there are two fish (and a tank, plants, etc.) but they experience Cognitive Dissonance if they try to make the fish move.  I say if, because they may not care to make the fish move.  Now if they try to make the fish move, but can't figure out how or better yet, try the <forward b> tile and the whole tank moves, they get frustrated.  Frustration is a good thing (in my opiniion) and to be celebrated in class, because it means something doesn't match between the child's mental model and the way things work (which in this case is the way they work in the world of Etoys).  I am always interested in how to create Cognitive Dissonance and try to design a lesson to increase the likely hood of this happening.  I will also try to understand children's mental models and then find a situation where their mental model will break and present it to them as a problem.  The challenge is creating an environment where this is celebrated and the child congratulated for finding a situation where their mental model doesn't match the "world" whether that be our physical world or the Etoys world. Unfortunately most children are taught to avoid situations where they are wrong, rather than to search them out and see them as opportunities to learn.

Now in regards to your central question "create things that work separatly and program them, step-by-step."
One way to think about this is to think about the "ladder of abstraction" (see Brian Harvey's explanation of this here).  Brian explains the different levels of abstraction in discussing driving a car. This is good for thinking about the different level of thinking about things and what are the useful abstractions depending on whether you are driving the car or perhaps designing a part of the car and what level of abstraction is appropriate and useful.

Bret Victor's Up and Down the Ladder of Abstraction is another excellent resource.  It could be used with and to expand upon the Etoy's Challenge.  Brett (to me at least,
talks not just about "The Ladder of Abstraction" but how do use wonderful visualizations and techniques (such as small multiples and graphing the time dimenstion) 
allowing the user to step through the algorithm visually at their own pace and ways to see the effects of changes in variables on the algorithm.

I seem to recall some things from Society of the Mind that could apply, but can't find my copy at the moment.

Hope this helps,
Stephen

P.S. As per an email from Alan Kay here:
I thought of objects being like biological cells and/or individual
computers on a network, only able to communicate with messages (so
messaging came at the very beginning
While "object only able to communicate with messages" does happen in Etoys this is a bit "under the covers" and not as visible as it is in the Scratch model where they use broadcast and receive tiles to allow objects to communicate.  Although I would think using Tests is also a way that objects "communicate" using <color sees> and <overlaps> tiles and then interacting with the mouse using other tiles.

Hi all,

as studying for my master degree, Im trying to explain as accuratly as I can the ideas that are behind Etoys. Its funny how hard it is to explain something when you are working with it involved with it...
As a psychologist (doing a master degree in psychology department ;)), what im trying to do is to show the theory behind Etoys to people who dont know almost nothing about it.
It could sound a strange task, but what Im trying now is to explain to people the notion of "object". Then, I wonder:
What is an object in Etoys, how could we define an object?
Maybe I should better explain this. For example: while working with  8,9,10 years old children here, a curious thing im seeing is that the notion of an object (as an independent thing, that belongs to a world - wich is also an object- but works independently from it, that has its features, handles, functions, etc) is not a given thing for them. For example, even many times later then Ive shown it and explained it, children could still be drawing many things together, just to "keep" them and realize (frustrated, sometimes) they come as the same object. Of course it depends on the kid, but it could take some time after they start realizing it and creating them separatly... And even after that, I think this is a central question working on Etoys: create things that work separatly and program them, step-by-step.
Children (and this goes to many adults as well) start thinking all together, like a big idea, and to realize that programming require thinking in levels, or steps, is a major idea of the thing...
Maybe (hope not!) im being a bit confusing, but i was just wondering if you guys have some ideas of papers, researches, etc that explain or talk about these ideas, or how Etoys was thought (if was) related to the notion of object. 

all the best,

Bruno

Dear educators,

I'm sorry but I'm stuck in the office with a print job that might take another hour and I'll not make it for our meeting in time. I'll try to start a hangout at 1 pm EDT / 10 am PDT, I hope to see you then!

Greetings,

arabic Etoys?

Hi everyone,

today I have been asked if there is an arabic version of Etoys. There is one on the pootle server, so I assume it is possible to use Etoys with it. Am I right that you just need the correct font on your computer? Or is there something else that needs to be installed?

Greetings,
Rita
