Classrooms Need Cooling, Park Says

Assistant Professor of Public Policy R. Jisung Park was featured in a Marketplace report about the impact of air conditioning on student performance. Park has conducted several studies investigating how heat affects student performance in the classroom, and his research shows that students learn less overall when they experience more hot days. “It’s a slow, hidden burn,” Park explained. “These little disruptions to learning, maybe we don’t notice them on a day-to-day basis, but over time they appear to add up to something meaningful.” Many of America’s school buildings do not have air conditioning, and some have no cooling at all. “The Goldilocks zone seems to be somewhere in the mid-60s” to achieve optimal learning outcomes, Park said. Now, many public schools are choosing to use some of their federal COVID relief funds to upgrade air conditioning, which improves air quality and should also improve student academic and health outcomes.
