Multiple international education reports have identified excessive electronic device use as the top obstacle to student achievement worldwide. Prolonged screen time is causing reduced concentration, academic burnout, and a serious decline in educational quality across all levels.

In countries and regions that have already introduced smart devices into schools, research shows that students spend an average of over three hours per day on screens for non-educational purposes. Time devoted to social media, short-form videos, and gaming far exceeds that spent on studying.

Education experts attribute this trend to "attention fragmentation," which directly impairs students' ability to read long-form texts, weakens their capacity for deep thinking, and exacerbates issues such as sleep deprivation and anxiety. Data from the Programme for International Student Assessment (PISA) further indicates that each additional hour of non-learning screen time per day is linked to an average decline of approximately nine points in mathematics scores.

In response, educational institutions in multiple countries have begun implementing countermeasures. Some schools are adopting "phone-free classroom" policies and introducing courses designed to enhance student focus. At the same time, digital wellness tools, such as Apple's "Screen Time" feature, are being increasingly used by families to monitor and limit device usage, as well as to schedule periods away from screens. These efforts aim to help students regain control over their time and attention.
