A Cross-Cultural Study on the Impact of Social Media Usage on High School Students’ Learning

This cross-cultural study investigates the impact of social media usage on attention span, working memory, and focus among high school students in China and the United States, framed by Cognitive Load Theory (CLT). The research explores how multitasking and social media engagement influence learning processes by analyzing intrinsic, extraneous, and germane cognitive loads. Data were collected via a questionnaire survey from 153 high school students (105 Chinese, 48 American) in December 2024, with validated scales measuring cognitive load dimensions. Results revealed significant cross-cultural differences: U.S. students reported higher extraneous load, reflecting greater susceptibility to distractions from notifications and rapid content shifts, while Chinese students exhibited lower germane load, indicating challenges in leveraging social media for educational integration. Grade-level variations emerged, with seniors (Grade 12) experiencing elevated intrinsic load due to academic pressures and multitasking demands. Students from both nations acknowledged social media ’ s dual role — distracting through entertainment yet beneficial for resource-sharing and peer collaboration. Self-management strategies, such as device separation and app restrictions, were commonly employed to mitigate disruptions. The findings underscore the complex interplay between social media design, cultural contexts, and cognitive demands, highlighting the need for tailored educational strategies. Recommendations include integrating digital literacy programs, fostering balanced usage habits, and designing platform interventions to reduce extraneous load. This study contributes empirical insights into optimizing social media’s role in education while addressing its cognitive challenges.
