The Erasmus+ programme Outdoor Education for Museums and Cultural Organizations has compiled a comprehensive Handbook, available in four languages – English, Greek, Italian, and Spanish – to provide a holistic understanding of this enriching approach to learning. Delve into the theoretical foundations of outdoor education in Greece, Italy, and Spain, and uncover practical educational activities from each partner organization that exemplify the principles of experiential learning in the outdoors. This valuable resource serves as an essential guide for educators, trainers, and anyone aspiring to incorporate outdoor education into their curriculum or practice.
