Park on New Research on Heat, Learning and the Racial Gap

The New York Times spoke to R. Jisung Park,, associate director of economic research at the UCLA Luskin Center for Innovation, about new research showing that hotter temperatures widen the racial achievement gap in U.S. schools. Park’s study found that students performed worse on standardized tests for every additional day of 80 degrees Fahrenheit or higher, suggesting a fundamental link between heat exposure and reduced learning. While those detrimental effects were observed across 58 countries, the U.S. data revealed a surprisingly pronounced effect on Black and Hispanic students, the study found. Park, an assistant professor of public policy, said the gap seemed to reflect the fact that minority students are less likely to have air-conditioning at school and at home. Being exposed to higher temperatures throughout the school year appears to take a cumulative toll, he said. “It’s like a thousand little cuts to your ability to focus and concentrate and learn,” Park said.
