Since the key to success of the nature-centered ecological program depends so heavily on direct personal experiences with living organ- isms and their habitats and on doing studies outdoors, it is important that ample time be allowed for the program, especially at the primary and middle school levels when children are at a formative stage. This can be fully justified because later on, in addition to the scientific and attitudinal goals, the program can make important contributions to virtually all other disciplines, including writing and art. It can be made highly interdisciplinary. In this chapter, the author discusses how to establish and maintain a Nature-Centered educational program.
