Recent advances in digital technologies offer teachers today an array of innovative tools and resources that can help them respond to students' diverse learning needs. For Environmental Studies, Social Studies and Science teachers, the genre of interactive multimedia presents exciting opportunities for the development of the students' understanding of critical issues in environment conservation. In particular, the simulation form of interactive multimedia enables students to gain instant feedback on the effects of their decisions and actions on the environment.
In the Philippines, such simulation programs are not readily available to environmental studies teachers. Programs that are situated in the real life experiences of communities faced with the challenges of sustainable development are even more difficult to obtain. In response to this need of providing locally-contextualized learning materials, an interactive multimedia CD-ROM simulation program called "The Last Resort" was designed to help students in secondary level and tourism majors at the tertiary level examine the inter-relationship of environmental protection, ecotourism and sustainable development.
The problem of designing a pedagogically rich interactive multimedia program on sustainable development was addressed by integrating a goal-based scenario design framework with the interface design. The constructivist orientation of such a framework enabled the interface and instructional designer to provide a technology-supported learning environment where students learned key aspects of sustainable development by direct manipulation of different program functions and simulation and investigation of alternative scenarios.
