Middle-school aged children should limit their recreational screen time to no more than one hour daily on school days and four hours a day on weekends, researchers say.

A new study shows that kids who use the internet, social media, or video games recreationally for longer have significantly lower grades and test scores.

“Interactive technology is widely used to promote children’s educational access and achievement,” says lead author Vivien (Wen Li) Anthony, an assistant professor at the Rutgers University School of Social Work and research associate at the Rutgers Center for Gambling Studies.

“During the COVID-19 pandemic, technology has been essential to facilitating remote learning. At the same time, there is a growing concern that excessive technology use, particularly for entertainment, may adversely affect children’s educational development by facilitating undesirable study habits and detracting from time spent on learning activities.”

The researchers analyzed the China Education Panel Survey data, a national survey of educational needs and outcomes of children in China. They surveyed and followed approximately 10,000 first-year middle school students. Their average age was 13.5 years.

The results show that children who used the internet, social media, or video games for entertainment four or more hours daily were four times more likely to skip school than those who did not. Boys used interactive technology for entertainment significantly more than girls. Boys also performed worse and showed lower school engagement levels than girls.

“Such findings are critical, particularly in light of the recent movement toward online learning in countries throughout the world,” says Anthony. “In a learning environment that integrates the internet, it is easy for children to move across educational and entertainment platforms during learning without alerting teachers or adults to alternate activities.”
