“…The outdoor environment of primary schools, although a sizeable element of the primary school premises, is often ignored in school-design, as it is not typically used for formal instruction (Armitage & Burke, 2005;Kasali & Dogan, 2010). Indeed, the design of school grounds and its potential impact on children's learning has not attracted the same level of interest as the design and space within classrooms (Armitage & Burke, 2005;Barrett, Davies, Zhang, & Barrett, 2015;Kellock & Sexton, 2017). Despite this, a growing body of research has associated spending time in the outdoor environment with attention restoration, recovery from stress, informal learning through play, improved physical activity and improved academic attainment (Chawla, Keena, Pevec, & Stanley, 2014;Mårtensson et al, 2014;O'Brien, 2009;O'Brien, Murray, Liz, & Richard, 2007;Ward Thompson & Aspinall, 2011).…”
