More Screen Time Linked To Lower Test Scores For Elementary Students

A study followed more than 3,000 kids in Ontario over a 15 year span from 2008 to 2023, tracking how much time they spent watching TV or DVDs, playing video games, using the computer or playing on handheld devices like iPads, as reported by their parents. That data was compared to their EQAO standardized test scores, which are used to assess the reading and math skills of kids across Ontario in grades 3 and 6. The findings point to a “significant association,” between screen use and lower test scores, according to Dr. Catherine Birken, a pediatrician and senior scientist at Sick Kids and lead author of the study.

“For each additional hour of screen use, there was approximately a 10 percent lower odds of meeting standards in both reading and mathematics … in Grade 3 and mathematics in Grade 6,” said Dr. Catherine Birken, a pediatrician and senior scientist at Sick Kids and lead author of the study, in an interview with CBC News. The study didn’t differentiate between different types of screen time — for example, whether a child was playing a game on their iPad versus FaceTiming a relative in another city, or watching an educational video. It was also an observational study that relied on parents answering questionnaires about how much time their kids spent in front of screens. The study authors note that this means the research can’t be taken as definitive proof that screen time causes lower grades, just that the two things tend to go hand in hand.
