ScratchEd – Community site for educators using Scratch

Alfred Thompson shares, "The people at the Lifelong Kindergarten Research group at MIT recently unveiled ScratchEd a new community site for educators who are using Scratch." Scratch was designed at MIT and, as described by Wikipedia, "has the goal of teaching programming concepts to children and teens and letting them create games, videos, and music." Unlike Squeak, on which it is based, Scratch is dynamic, allowing code to be changed while running, and hence, users to interact with it and see what happens.

"Unlike Squeak, on which it is based, Scratch is dynamic, allowing code to be changed while running..."

Hmmm...I thought Smalltalk (and Squeak) were known for pioneering dynamic code translation. I always assumed this was one reason that the MIT group decided on Squeak as their base.

Ah - yes, that's an interpretation I brought into the article, and as you suggest, an incorrect one. [Comment] [Permalink] [Previous][Next]

Yes, Squeak is dynamic. Scratch is more polished graphically, and my 6th grade students prefer it because of that. But Squeak also allows you to update the code and watch its effects dynamically. Which is a powerful learning tool, btw. [Comment] [Permalink] [Previous][Next]
