I will present botsInc an environment to teach programming to novices of all ages. http://smallwiki.unibe.ch/botsinc/
Here is an extract from my book" My goal is to explain key elementary programming concepts (such as loops, abstraction, composition, and conditionals) to novices of all ages. I believe that learning by experimenting and solving problems with fun is central to human knowledge acquisition. Therefore, I have presented programming concepts through simple but not trivial problems such as drawing golden rectangles or simulating animal behavior. The ideal reader I have in mind is an individual who wants to have fun programming. This person may be a teenager or an adult, a schoolteacher, or somebody teaching programming to children in some other organization. Such an individual does not have to be fluent in programming in any language. As a father of two young boys I also wrote this book for all the parents that want to have fun programming with their kids in a powerful interactive environment. Programming in Smalltalk is an interactive, fun but deep experience.
The environment that I developed is totally free and under the MIT open-source license following the open-source philosophy of Squeak."
