The microworld is build of the book and a number of Logo projects. Each of these project is a kind of learning micro-microworld which provides the student with an opportunity to observe and examine various facets of randomness (like important characteristics of random variables) without - and long before - introducing any formal definitions. This attempt is not against formalism. On the contrary. The main goal is to help the student in harnessing formalism, making it understandable and handy. And to develop the need for formalism.
The book starts with a number of relatively easy examples and problems. The main goal is to give a student the feeling of randomness. Gradually the proportion of abstract models grows. Apart from traditional representations like mathematical equations we introduce other new tools of expressing ideas: the formal definitions of procedures in Logo. These definitions are usually very short and simple, but this doesn't mean easy.
