This digest provides a framework for professional development of outdoor educators. Outdoor and environmental educators share similar principles of outdoor learning. Thus, the performance standards recently drafted by the North American Association for Environmental Education (NAAEE) can serve as a useful guide for outdoor education generally. NAAEE-recommended competencies fall into seven categories. First, knowledge and skills are needed in such areas as safety, group management, problem solving, technical equipment, environmental protection, and expedition planning. Second, teacher understanding of basic education foundations, current educational theories, and children's physical and intellectual development is as important for outdoor learning as in the classroom. Third, educators interested in conducting outdoor education experiences regularly would benefit from a grounding in the history and evolution of outdoor education and its methodology. Fourth, outdoor educators should have the knowledge and skills needed to awaken in students an environmental sensitivity or appreciation. Fifth, use of a variety of teaching methods to directly involve students in exploring the world around them fosters creativity and critical thinking. Sixth, capable outdoor educators create a safe place for learning that encourages exploration and discovery and provides an open and stimulating environment. Finally, outdoor teachers need skills in assessment practices. (SV)
