Information literacy is the ability to use information purposefully and effectively. It is a holistic, interactive learning process encompassing the skills-based phases of defining, locating, selecting, organizing, presenting, and evaluating information from sources that include books and other media, experiences, and people; being able to consider information in light of knowledge; adding information to current knowledge; and applying this knowledge to solve information needs. An approach for promoting information literacy and establishing an integrated information skills program in a school is described. At Marist Sisters' College, a secondary school in Sydney (Australia), an action research project has attempted to place information literacy at the center of the curriculum. Using R. G. Havelock's model of the change agent, a range of change agent activities has been used. Qualitative evaluation through interviews with 8 teachers and 110 students in grades 7, 9, and 11 has demonstrated the positive impacts of the approach on student self-concept, the learning process, the view of information, learning outcomes, and the learning environment. Three appendixes contain a summary of the information process, change agent activities, and a diagram of the planning model. (Contains 12 references.) (SLD)
