In addition to the positive results, the academics discuss what it is about lessons in nature that may make the difference, highlighting previous research findings on: the benefits
of physical activity (in this study the class walked 200 metres to get to the grassy area); exposure to nature being good for stress and attention; having a break from the classroom and
change of scenery (a similar effect to going for recess); and the fact the teachers would also too feel less stressed and benefit from the same
change of scenery and a «bit
of a breather».
