Ted Leung reports on what he's using to teach his girls about programming:
The new regimen involved another Windows shortcut to pop up Notepad. The girls then had to learn to save a file, switch windows (on purpose, not by accident) to the Python interpreter window, reload the module, and look at the Tk output window. I found myself barraged by questions that had nothing to do with turtle geometry or programming. All the questions were about the environment -- forgetting to save a file, getting windows out of focus or behind each other, forgetting to reload the module, etc. I suppose they were learning computer "literacy", but it really reminded me as to how much stuff you need to know in order to do some simple programming. In a way, it was easier when I was doing AppleSoft Basic on the Apple II -- no separate editor, no windows to lose or have out of focus.
At Mind Camp, Todd Blanchard brought by a copy of "Squeak: Learn Programming with Robots", and the girls got excited by paging through it. It looked pretty good, and Squeak/Smalltalk certainly has the programming constructs that I want my kids to be exposed to straight off (at least if they are going to be programmers). Also, one of the original motivations for Smalltalk was for allowing kids to do programming and simulations, and that heritage seems to have carried through into the Squeak community. For a great/depressing look at some of the learning applications, you can check out this video from ETech 2003.
For teaching software neophytes, nothing stays out of the way and lets you learn like Smalltalk. Which makes you consider the impediments that most people have just gotten used to :)
