[OLPC Bolivia] [IAEP] How can we help kids get into the habits of looking for all possible causes and counter examples to problems?

Excelente mensaje Paolo: siempre recuerdo que en mi infancia en Uruguay me explicaban que la luna crece cuando tiene forma de "C" y decrece cuando tiene forma de "D".

Deseo agregar un punto a tu mensaje:

Hay un porcentaje considerable de uruguayos que tenemos familiares y amigos viviendo en el extranjero. 

No sé si ya se está haciendo,  pero pienso que en muchas aulas sería posible realizar experimentos como el que describes de que un niño tome una foto de la luna y la envíe por correo electrónico a otro niño en el hemisferio norte. 

El niño lejos de Uruguay no tiene por qué ser necesariamente un familiar o un amigo.  Podrían ser familiares de los muchos visitantes que recibimos en Uruguay.  Podrían ser grupos que ya han demostrado interés en corresponder con niños de otros países.  

Tal vez algunos recuerdan a Randy Caton;  muchos uruguayos lo conocieron en ocasión de Squeakfest 2011 en Mayo último.  Randy trabaja como voluntario con los niños de una reservación indígena en EEUU que desean comunicarse con niños en lugares lejanos.  

En Alemania está Radio JoJo que pone en contacto a los niños de Berlín con los del resto del mundo.

Hay escuelas para niños uruguayos en varios lugares del mundo.

English translation:

Excellent message Paolo;  I always remember,  from my childhood in Uruguay,  being told the moon is growing in size when it has the shape of a "C", as in "crecer" or "to grow" and reducing its size when it looks like a "D" as in "decrecer".

I want to add one point to your message:

There is a considerable percentage of uruguayans who have family members or friends leaving overseas.

I don´t know if they are already doing it but I believe in many schoolrooms it would be possible to perform experiments like the one you describe of one kid taking a picture of the moon and emailing it to another kid in the northern hemisphere.

The child far from Uruguay doesn´t necessarily have to be a relative or a friend.  They could be the relatives of the many visitors we receive in Uruguay.  They could be groups who have already shown their interest in corresponding with children overseas.

Maybe some of you remember Randy Caton:  many uruguayans met him at Squeakfest 2011 last May.   Randy works as a volunteer with the children in an indian reservation in the U.S.A. who want to communicate with far away children.

Radio JoJo in Germany puts Berlin children in touch with children all over the world.

There are schools for uruguayan children in several locations around the world.

(the people that designs calendar on the south repeat like parrots the things that northern people designs, so they draw the moon in the opposite way....)
