In the past decade, an increasing number of Danish public, private and independent schools have introduced regular compulsory education outside the classroom for children aged 7-16 as a weekly or biweekly "outdoor school" day--known in Danish as "udeskole." An analysis of this form of outdoor education, its impacts and provision has been undertaken. Findings suggest that "udeskole" can add value to normal classroom teaching especially with regards to health, social and well-being perspectives. Future recommendations include collaborative strategies between researchers, local government sectors, and educational and landscape planners and managers to improve the impact and provision of "udeskole" in the Danish school system. Further, it is important to understand this grassroots movement of devoted teachers from both an educational and green management perspective. (Contains 2 figures and 1 note.)
