This study investigates the advantages and disadvantages of outdoor pedagogy for years F-3. By spending time outdoors, the pupils take part in activities they are unable to experience in the classroom. Outdoors, the pupils get the opportunity to investigate, discover and explore with all their senses. This makes the learning experience more profound. Children are currently spending more time than ever inside and infront of different types of screens, which is yet another reason why it is of great importance to allow the children to spend more time outside and in nature. Teaching outdoors enables the children to move around more freely and get fresh air, which promotes good health and an increased ability to concentrate. We have decided to investigate the advantages and difficulties with outdoor pedagogy. This study has been conducted through systematically searching for reports about outdoor pedagogy and its advantages and difficulties. The method used is based on searches in different data bases, using relevant terminology. The results of this study have shown several advantages such as increased knowledge, mental and physical health benefits, and a positive attitude towards caring for the environment among the children. The difficulties that have appeared are lack of time and the restrictions placed on the teachers due to the curriculum, but mainly the teacher's own lack of knowledge and confidence regarding outdoor pedagogy.
