Title: The Impact of Social Media on Students' Academic Performance: A Meta-Analysis

Abstract: 
Social media use among students has become increasingly prevalent, but concerns have been raised about its impact on academic performance. This meta-analysis synthesizes findings from 32 studies (N = 18,388) examining the association between social media use and academic performance. Results indicate a small but significant negative relationship between social media use and academic performance (r = -.17, 95% CI [-.20, -.13]). The negative impact was greater for higher levels of social media use and for specific platforms, such as Snapchat and Instagram. The moderating effects of age, gender, and academic level were also examined. Implications for future research and interventions are discussed. 

Keywords: social media, academic performance, meta-analysis.
