This article focuses primarily on our research group's year of preparation before the opening of a new K-7 publicly funded ecological "school" for students aged 5-12. The article begins with a discussion of the reasons for seeking ways to change the values of a culture which fails to confront the consequences of its destructive practices, and for looking for a new approach to ecological education which sees the more-than-human world as an integral part of the learning situation. Five principles are introduced and explained--principles that have grown out of the evolving experience of the research group, and then four "slogans," which have served to guide the ongoing work of development, are described and illustrated. As part of the purpose of this project to change social and cultural values, the change of values within the research group during its ongoing work is also explored. (Contains 21 notes.)
