Introduction
There is an increasing tendency among Danish teachers to introduce outdoor learning for children aged 6–16 on a weekly or biweekly ‘Outdoor School’ day, often called udeskole in Danish. This is happening in both private and public schools and at grade levels from 0 to 10. Outdoor School is characterised by compulsory educational activities outside the school buildings on a regular basis and can take place in various settings, such as forests, parks, local communities and farms (Jordet, 2007). Outdoor School comprises a range of activities, and there is often a focus on practical and direct experiences while specific subjects and themes within the written curriculum are being covered, for example, mathematics, language and history (Jordet, 2007).
