What if what is outside a school’s windows is as critical to learning as what’s inside the building? A fascinating new study of high school students in central Illinois found that students with a view of trees were able to recover their ability to pay attention and bounce back from stress more rapidly than those who looked out on a parking lot or had no windows. The researchers, William Sullivan, ASLA, professor of landscape architecture at University of Illinois at Urbana-Champaign, and Dongying Li, a PhD student there, reported their findings in the journalLandscape and Urban Planning.
