Teaching lessons outside the classroom is not yet a widespread practice in France, although it has recently grown in popularity as a result of the COVID-19 health crisis. At a primary school in Mancenans (Doubs), several teachers spend one half-day a week giving lessons in the nearby forest, even in winter. According to the teachers and the parents questioned, this provides countless benefits for the children: improvements in well-being at school, self-esteem, independence, and in their ability to create and communicate. The teachers also benefit: they feel that their job has a new meaning.
