[1] High schооl students perfоrm better on tests if they аre in а clаssroom with a view of a green landscape, rather than a windowless room or a room with a view of built space, according to research from the University of Illinois Department of Landscape Architecture. [2] The research found that students with a green view outside a classroom window performed better on tests requiring focused attention and recovered better from stress. It is the first study to establish a causal relationship between exposure to a green view and students’ performance, said William Sullivan, head of the landscape architecture department. [3] “It’s a significant finding, that if you have a green view outside your window, you’ll do better on tests,” said Dongying Li, a doctoral student who conducted the research with Sullivan. Students’ capacity to pay attention increased 13 percent if they had a green view outside their classroom window, the study found. [4] The research involved 94 students at five central Illinois high schools. Students were randomly assigned to one of three types of classrooms – windowless, with a window looking out onto built space (such as another building front or a parking lot), or with a window looking out onto green space. Each type of classroom had a similar size, layout and furniture. [5] The findings: Students did better on the attention tests given after the break if they were in a classroom with a green view, Li said. Those students showed a 13 percent increase in performance following the break. There was no statistical difference in performance for the students in the windowless room or the room with a view onto a built space. Similarly, the students in the room with the green view showed a greater physiological recovery from stress after the break than the other students. Views of nature enhance recovery from stress, and the students with a view of a green landscape showed a greater recovery from stress. [6]The researchers suggest their findings can help designers, planners and policymakers enhance students’ well-being and learning. For example, planners can identify sites for new schools that already have trees and other vegetation, or they can plant many trees on the site; architects can locate classroom, cafeteria and hallway windows so they look onto green spaces; and school schedules can allow short breaks to restore students’ attention and help them recover from stressful tasks.
