Screen Time and Academic Performance in Elementary Students
Negative Association Between Screen Time and Academic Performance
Multiple studies consistently show that higher screen time is linked to lower academic performance in elementary and early adolescent students. Children who spend more hours watching television, playing video games, or using computers and the internet tend to have lower grades in subjects like mathematics, reading, and physical education, as well as lower overall grade point averages and reduced learning abilities Gupta2023Adelantado‐Renau2019Zapata-Lamana2021+7 MORE. This negative association is observed across different countries and age groups, and it applies to both boys and girls Zapata-Lamana2021Khan2022.
Type and Timing of Screen Use Matter
Not all screen activities have the same impact. Watching television and playing video games are particularly associated with poorer academic outcomes, including lower composite scores, language, and mathematics performance Adelantado‐Renau2019Zapata-Lamana2021Khan2022. The timing of screen use also plays a role: using screens immediately before bedtime is linked to even greater reductions in academic performance, as well as other health issues like dry eyes and obesity .
Duration of Screen Time
The amount of time spent on screens is important. Students who limit their recreational screen time to less than one hour per day or do not use screens daily tend to have higher academic scores Gupta2023Mineshita2020Marciano2021+1 MORE. In contrast, those who exceed two hours per day of screen use are less likely to report high academic performance Khan2022Marciano2021Howie2020.
Screen Time, Cognitive and Behavioral Effects
Excessive screen time is not only associated with lower grades but also with cognitive and behavioral problems. Students with higher screen use report more difficulties with memory, attention, and problem-solving in class Zapata-Lamana2021Sidiq2025Cerniglia2020+1 MORE. Increased screen time is also linked to higher levels of anxiety and behavioral issues, which can further impact academic success Sidiq2025Cerniglia2020Paulich2021.
Meeting Screen Time Guidelines Improves Outcomes
Meeting international recommendations for screen time (less than two hours per day) is associated with better academic achievement. When students also meet guidelines for physical activity and sleep, their academic performance improves even more Marciano2021Howie2020. Media multitasking—using multiple devices at once—has an additional negative effect on academic achievement .
Socioeconomic Factors and Screen Time
While screen time has a measurable effect on academic performance, socioeconomic status (SES) is often a stronger predictor of academic outcomes. However, the negative impact of excessive screen time remains significant even after accounting for SES .
Conclusion
In summary, excessive screen time—especially television viewing and video gaming—is consistently associated with lower academic performance in elementary students. Limiting recreational screen use to less than two hours per day, avoiding screens before bedtime, and reducing media multitasking can help support better academic outcomes. While other factors like socioeconomic status also play a role, managing screen time remains an important strategy for improving school performance in children.
