In ARI@ITALES the microworlds are environments in which it is possible to build solving processes for the problems.

The microworlds of ARI@ITALES provide the user some basics (objects and functions) that can be arranged to produce some effects (computational, graphic,...).

The microworlds incorporate a sphere of knowledge described in a model. They supply many ways to reach a fixed objective and they allow, among other things, the direct manipulation of objects.
