Greenfoot is an interactive environment based around Java that enables two-dimensional graphical games and simulations to be set-up relatively simply. Currently maintained by the University of Kent, UK and La Trobe University, Australia, it provides a piece of free software (under a GPL licence), multiplatform and is multiplatform.
In this paper its use within the teaching of problem-solving and artificial intelligence will be considered. Three case studies of it use will be considered:
· Exercises in developing problem solving within a problem-solving and programming module.
· Greenfoot for a problem solving assignment within a problem-solving and programming module.
· Use of greenfoot within a module on artificial intelligence.
