Presbyterian Ladies College (PLC) is a 130-year-old independent girls' school in the eastern suburbs of Melbourne. Teaching students from ages 4 to 18, PLC has a reputation for academic excellence. Geography is a separate subject taught as a part of the core curriculum in the secondary school. The College, which uses principally Macintosh computers, seeks to integrate ICT (information and communication technology) within the curriculum. The introduction of GIS (Geographical Information Systems) is one example of this. After spending seven years exploring how best to integrate this new technology into the Geography classroom, the school has identified eleven key factors considered necessary for a successful integration process.
