A while back I read on Ted and Julie Leung's respective blogs I read about Squeak: Learn Programming with Robots. I was amazed how impenetrable this system, ostensibly designed for children, was to me. I have tried in the past to understand the Squeak environment, and to grasp eToys. One more tool we've begun to explore is Squeak/eToys. There is a steeper learning curve to literacy with Quartz Composer. While my seven-year-old can create some effects by playing around with the patches and randomly wiring them up, the system as a whole has been too abstract for him and he doesn't get it the way he gets Scratch. A composition can be saved and used in various Cocoa programs that take *.qtz files as plugins, such as the Screen Saver or iChat. This is a popular tool with VJs, and there is a community around it for sharing custom patches and compositions. Different patches have different numbers of connectors and there are a wide variety of patches to choose from, along with template starter projects for screen savers, audio visualizers, and more.

Rather than snap-together blocks, as in Scratch, it is a patch-based environment (there are many of these for working with audio): You drag patches onto a workspace, then wire them up by dragging from the output of one patch to the input of another.

This is a program that comes with Apple's free Developer Tools. Scratch runs on both Windows and OS X, with a port to Linux being worked on, but as a Windows-free household, GameMaker is right out.Īnother interesting system we've been playing around with lately is Quartz Composer. Besides being commercial, it is also Windows-only, which makes it a non-starter in my household. One option that is often suggested as a step up from Scratch is GameMaker, which apparently is a very nice commercial system that lets kids build games. It is a great environment for learning to think creatively within its constraints, but my kids also bump up against its limits pretty quickly. It also has some pretty severe limitations: no user-defined blocks, no return values, no file interaction (so no high scores), no network interaction, no dynamic object creation, the program cannot draw on sprites (only on the background), no string variables or any real string handling.

My seven-year-old can download someone else's project and generally is able to read it to see what is going on, so it is good for building basic programming literacy. Scratch is great for learning and for sharing. They can also share their creations on the web, projects get automatically converted to Java applets when shared on the Scratch website, and the kids can vote for and comment on each others projects. Scratch allows kids to program without worrying about the syntax, so they can drag blocks together, use the built-in drawing program to create sprites or import images from the library that comes with the environment. The best language for getting kids interested and up to speed quickly that I've found is Scratch, which is a visual, drag-and-drop programming language for games and animations based on Squeak Smalltalk. Let's look at both of these.įor languages other than Python, there are some really good choices. Two, find (or make) ways for Python to be more approachable. One, let them use other languages than Python.
So I see two approaches to this problem, if it is a problem.
Lately my kids have been very interested in programming, and I've found that Python doesn't come as easily to 6-11 year olds as it does to adult programmers.
Python has a well-earned reputation for being easy to use and to learn, at least for people who have learned programming in other languages first.
