Abstract
This paper describes the Environmental Challenges Project which will culminate in the production of a CD-ROM for use in environmental education in secondary schools. Disk contents include case studies of environmental problems and programs to facilitate learners' discussion of the issues raised. The constructivist pedagogy that informs the project is outlined with emphasis placed on two concepts: (1) scaffolding, which involves the provision of a conceptual framework within which learners can build their own understanding; and (2) a concept which involves the transformation of raw data into information using Stafford Beer's definition of information. A description of the functionality of the programs on the disk, 'Making Choices' and 'Bubble Dialogs', and the way in which these support the pedagogical approach of the project is provided.
