A virtual journey within the rock-cycle: A software kit for the development of systems-thinking in the context of the Earth's crust

Developments in the last few years in earth science education can be characterized by a shift towards a systems approach to teaching and curriculum development. The software "A Virtual Journey within the Rock Cycle", a microworld game, was developed in order to assist junior and senior high school students, who have already learned about the rock-cycle's processes and products, in developing a dynamic and cyclic understanding of the earth's crust system. Preliminary observations indicated that the software induced great enthusiasm, fostered collaborative group work and brought students to recall and reflect upon knowledge previously learned. Additionally, it was found that the teacher's role as a mediator was critical for enabling students to maximally benefit from the software.
