„Data from PISA 2022 indicate that while a short amount of time spent on digital devices for learning in school per day can enhance student performance, additional time beyond the first hour is typically associated with a decline in performance. According to students’ reports, the average time spent learning via digital devices per school day exceeds one hour in all OECD education systems, with an average of two hours.“
