BlueJ is in fact so simple to use that it is possible to bring the teaching of Java even, further down in the curriculum-into high schools. The plan for the immediate future is now for the developers at Monash to work with IT teachers of secondary schools to start using BlueJ at Victorian high schools. BlueJ is free, an attribute which provides a major benefit for all of the institutions teaching with it.
Students can install a copy at home at no cost.
