The Blueroom is a community site for educators using BlueJ. Its purpose is to share resources and have discussions with other educators and the BlueJ development team. The BlueJ environment was developed as part of a university research project about teaching object-orientation to beginners. The system is being developed and maintained by a joint research group at La Trobe University, Melbourne, Australia, and the University of Kent in Canterbury, UK. The aim of BlueJ is to provide an easy-to-use teaching environment for the Java language that facilitates the teaching of Java to first year students. Special emphasis has been placed on visualisation and interaction techniques to create a highly interactive environment that encourages experimentation and exploration.
