Environmental education

Environmental education (EE) is a learning process about how natural environments function and, particularly, how human beings can manage their behaviour and ecosystems in order to live sustainably. [It] increases people's knowledge and awareness about the environment and associated challenges, develops the necessary skills and expertise to address the challenges, and fosters attitudes, motivations, and commitments to make informed decisions and take responsible action. Outdoor education and experiential education complement environmental education.

Outdoor education means learning "in" and "for" the outdoors. It is a means of curriculum extension and enrichment through outdoor experiences."
Experiential education is a process through which a learner constructs knowledge, skill, and value from direct experiences" Experiential education can be viewed as both a process and method to deliver the ideas and skills associated with environmental education.
In psychosocial terms, outdoor education may be defined as the use of experiences in the outdoors for the education and development of the whole person. In this sense, Outdoor education offers informal educational opportunities addressing the personal and social development of both communities and individuals. In environmental terms, outdoor education may be defined as education in, for, and about the outdoors. The emphasis is then placed on relationships concerning human and natural resources.

More broadly, outdoor education may be defined as an emphasis on direct experience of the outdoors for personal, social, educational, therapeutic and environmental goals.  In that case, outdoor education includes environmental education, conservation education, adventure education, school camping, wilderness therapy, and some aspects of outdoor recreation. The Scout Movement for example, use outdoor education for both psychosocial and environmental objectives. It is an experiential method of learning by doing involving small groups of people in organised adventurous activities in natural settings and primarily using themselves as the resource for solving problems.
