Schools Should have Enough Green Spaces

Education Information

Children today spend less time outdoors than ever before - and it is a concern not only affecting their physical health, but also their cognitive development.

A study, recently published in the Proceedings of the National Academy of Sciences, found that elementary school children who were exposed to more green spaces within or directly outside their school showed improved learning and memory.

The findings reinforce that of a recent six-year study on 905 Massachusetts public elementary schools, which found that students in schools that had more "greenness" in their surroundings reported higher scores on standardized testing in English and math.

The new study was conducted on more than 2,500 children in second, third and fourth grade at 36 primary schools in Barcelona, Spain. At the outset of the study and again 12 months later, the children were given computerized tests measuring cognitive functions, including working memory (a measurement of short-term memory) and attentiveness. The researchers also measured the green spaces within and surrounding each school.


They found that the students who attended schools with more green spaces showed a 5 percent improvement in working memory, a type of short-term memory that's critical for reasoning, learning and comprehension. Their inattentiveness also decreased slightly.

The study reveals the possible reasons too. Being in green spaces increases physical activity, which is known to improve children's cognitive performance. Playing outside itself allows children to exercise important cognitive functions.

Protection from pollution is another factor. The researchers estimated that reductions in exposure to traffic-related air pollution might account for anywhere from 20 to 65 percent of the improvements in cognitive development.

Spending time outside could have a number of benefits for children beyond improved memory and attention. Another recent study found that adventurous outdoor play -such as climbing, rough and tumble play, and exploring alone -improves children's physical health while also helping them develop creativity, social skills and resilience.


"Natural environments including green spaces provide children with unique opportunities such as inciting engagement, risk taking, discovery, creativity, mastery and control, strengthening sense of self, inspiring basic emotional states including sense of wonder, and enhancing psychological restoration," the study's authors write.

Fortunately, some schools are starting to take notice, creating more spaces for children to enjoy being in nature, including community gardens, outdoor playgrounds and small parks.
