Although the notion of Three-Dimensional (3-D) Textbook promises a lot of potential benefits to the teaching and learning in environmental education (EE), research on this subject is relatively scarce in the literature. There is limited information on how to transform physical settings into pedagogical tools for EE. In this article, the authors address this need by developing a design model for 3-D Textbook based on a qualitative case analysis conducted in Green School, Bali. Data were collected through a series of interview and on-site observation. These qualitative findings contribute to the development of themes and a design model that can be adopted by practitioners and future researchers in this direction. Additionally, this research brings to the practitioners' attention, the issues and criteria that need to be addressed in designing 3-D Textbook. Thus, this study is a significant attempt to reunite architecture and EE with a potential contribution to a field of knowledge that embraces design and science education. Designers and environmental educators interested in tapping the potential of physical environment as an instrument for knowledge transmission in schools will find this article useful.
